    Consistent Boost Levels on the 1.4T LUJ/LUV Engine

    Control your Boost Turbocharged engines rely one of a few different methods of controlling the boost level. Most modern-day gasoline engines rely on a “wastegate”, while diesel engines generally rely on Variable Geometry Turbochargers (VGT). In both cases, boost pressure and airflow is the result of engine exhaust gasses passing through the turbine of the turbocharger, of which the compressor shares a common shaft. Hence, turbine acceleration causes compressor acceleration which causes boost pressure and airflow to rise. With a wastegated turbocharger, the turbine and compressor speed are controlled by allowing a variable amount of engine exhaust gasses to bypass the turbine. With a VGT, the angle and shape of the turbine vanes can be changed on the fly, which affects the speed of both the turbine and compressor. VGTs are considered to be more efficient as the turbocharger's mechanical characteristics can effectively be changed, on the fly. (As an aside, the reason VGTs aren't prevalent on gasoline engines is because the exhaust temperatures tend to be much higher, although materials technology has caught up and VGTs are slowly making their way into high end gasoline engined vehicles like the Koenigsegg One:1) Wastegated Turbochargers The remainder of this article will focus on wastegated turbochargers (specifically internally wastegated turbochargers), since that is the type that is used in on the 1.4L turbocharged engine. In the age before Electronic Control Unit (ECU) controlled engines, the original wastegated turbochargers used a purely mechanical approach to controlling the boost. A calibrated “wastegate actuator” (WGA) would use spring pressure to hold the wastegate “default-closed”. Exhaust pressure levels “pre-turbine” (in other words, the exhaust pressure between the exhaust port and the “front side” of the turbine) rise in accordance with boost levels, and once there is sufficient pressure on the wastegate to overcome the spring weight in the WGA (sometimes called the cracking pressure), the wastegate will start to open and allow exhaust to bypass the turbine. This regulates boost pressure and airflow. LUJ/LUV Turbocharger turbine and internal wastegate (wastegate closed) LUJ/LUV Turbocharger turbine and internal wastegate (wastegate open) In the age of purely mechanical wastegates, it was relatively easy to increase boost levels beyond OE design specifications – all one had to do is install a heavier spring in the WGA, and the cracking pressure would increase, which would cause the turbine to spin faster, which in turn would cause the compressor to spin faster and compress more air. Of course, fueling and ignition advance curves would have to be modified, not to mention charge cooling systems as increasing the boost would also increase the amount of heat generated from compressing the incoming air. ECU Control – A Twist on Mechanical Wastegates When ECUs started managing engine operation, engineers had to come up with a method that would allow the boost to be regulated electronically, and, additionally through a closed-loop feedback system that would allow the ECU to compensate for changes in environment (air temperature, altitude, fuel quality) as well as changes to the engine operation as it wore mechanically. The earliest turbocharged engines from General Motors utilized a similar WGA as was from the mechanical days, with a twist: the addition of a pressure reference port which could effectively lower the WGA cracking pressure by applying pressurized air. LUJ/LUV Wastegate Actuator (WGA) In this system, there is also a boost control solenoid (BCS) which is essentially like an electronic diverter valve. By providing a Pulse Width Modulated (PWM) signal from the ECU, the ECU can control how much of the boost pressure coming from the compressor is allowed to be directed to the WGA. On General Motors vehicles, the usable PWM duty cycle range is 5% to 95%, where 5% causes the maximum amount of boost pressure to be directed to WGA, and 95% causes minimal amount of the boost pressure to be directed to the WGA. In other words, when the BCS command is 5%, the lowest amount of boost will be produced, and when it is 95%, the highest amount of boost will be produced. The following pictures show the BCS on the LUJ/LUV engine: LUJ/LUV Boost Control Solenoid (BCS) The ECU determines the “desired boost” level based on myriad decision inputs, including calibrated power limits, calibrated powertrain component limits (e.g. maximum turbocharger compressor speed), driver power demand, altitude, incoming air temperature, amount of historical knock, just to name a few. Once the ECU makes a decision on the boost level, it references a calibrated table to decide how much duty cycle should be output to the BCS, and drives (commands) the BCS to that duty cycle. The ECU then monitors incoming air mass via the Mass Air Flow (MAF) sensor, the intake Manifold Absolute Pressure (MAP) sensor, the Throttle Inlet Absolute Pressure (TIAP, or “boost”) sensor, and several Intake Air Temperature (IAT) sensors to determine if the turbocharger is operating as desired. If the actual boost level is lower than the desired boost level, this is considered an “underboost” condition and the ECU will make some dynamic increases to the BCS signal to try to correct the condition. If the actual boost level is higher than the desired boost level, this is considered an “overboost” condition and the ECU will dynamically reduce the BCS signal to try to correct the condition. In an overboost condition, it may take further, more drastic measures depending on the severity of the condition such as shutting down boost entirely, closing the throttle blade, or opening the bypass valve. This is done to protect the engine and its components (more on these conditions later). The ECU employs a Proportional-Integral-Derivative controller (PID controller) strategy to both immediately correct boost control errors, and also correct predicted future boost control errors. This is the “closed loop” portion of the system. The parameters of this system are part of the ECU calibration and can be modified as needed. This article won't go into depth regarding how a PID controller works, but there's a great reference on Wikipedia (https://en.wikipedia.org/wiki/PID_controller) that describes both the method and the mathematics behind it. Advancements in ECU Turbocharger Controls Since the original boost control system design on General Motor vehicles, two variants have come along. The first is used on the twin turbo V6 engines (RPO: LF3, LF4 and LGW). The system works very similarly to the “default closed” systems originally used, but in this case, the wastegates are “default open”. Mechanical spring pressure holds the wastegate open until boost is required. The advantage with this system is it allows for more efficient engine operation. If you consider the “default closed” system design, one drawback is the exhaust gasses are ALWAYS flowing through the turbine. Even under light duty, even where no boost is requested by the ECU, the exhaust still flows through the turbine, and the turbine still acts as an exhaust restriction, which reduces efficiency. The only way the wastegate can be opened is for the mechanical spring pressure to be exceeded, which can only happen when there's sufficient boost. The “default open” design aims to resolve this shortcoming. Instead of using positive pressure (boost) to control the WGA, negative pressure (vacuum) is used. When the WGA is subjected to atmospheric pressure, the wastegate is fully open. As the pressure supplied to the WGA drops, it starts to pull against a spring inside the WGA to close the wastegate. The negative pressure is generated by a mechanical pump driven by an engine component, and is controlled using a BCS which directs a controlled amount of vacuum to the WGA. It is essentially the inverse of the “default closed” system design. LF3 turbocharger with “default open” wastegate design This system is not without its drawbacks, however. It's significantly more complicated than the “default closed” system design because it relies on a system of vacuum pumps, lines and solenoids to control the turbocharger. Another interesting issue that has arisen on this system is the turbochargers can be noisy. The wastegate valve itself is a floating valve attached to the wastegate actuator arm. When the wastegates are open, they have a tendency to create an annoying rattling sound, and because the aim of the design was to keep the wastegates open under low power levels and at idle, the sound can be easily heard. General Motors even revised the turbocharger assembly several times in order to correct the problem. This cannot be an issue on “default closed” systems because the wastegate valve would be held against the wastegate orifice under these light load and idle conditions. But, on the very newest turbocharged engines General Motors is producing, such as the new 2.0L turbocharged engine (RPO:LSY), its larger 2.7L cousin (RPO: L3B), and the new 4.2L twin turbo V8 engine (RPO: LTA a.k.a. “Blackwing”), there's an exciting new technology being used! Doing away entirely with all of the pressure-based controls, the ECU now simply drives what is essentially the equivalent of a throttle blade actuator which directly drives the wastegate position. It also uses the “default open” design to improve efficiency. The aftermarket has not yet delved into calibrating any of these engines, so little is known about how effective this new solution is. Limitations with the Gen 1 1.4L Turbo Engine Wastegate System Now, we will discuss the specific issues with the LUJ/LUV engine turbocharger's wastegate system. The main issue we have observed is there can be quite a variance in the cracking pressure of the OE WGA assembly. Based on our years of experience in calibrating these vehicles, we can say that on average, a safe assumption is that the highest boost level that can be had on the OE WGA assembly, at sea level is around 20-22psi of boost. However, we've have also seen OE WGA assemblies that will support more than 25-26psi of boost. Our assumption is that because these vehicles, in stock form were never designed to make these kinds of boost levels, perhaps the manufacturing tolerances in the OE WGA is somewhat lax. When calibrating customer vehicles, however, we have to start with the lowest common demoninator or else our customers could end up with boost control diagnostic failures and subsequent “boost limp mode”. Collection of LUJ/LUV WGAs that all have different cracking pressures Adjusting OE WGA “Preload” a.k.a. “Playing With Fire” One of the classic (or perhaps “infamous”) techniques for changing boost levels (particularly before boost levels were managed by an ECU) was to adjust the length of the rod from the WGA to the wastegate arm. The original intent of using an adjustable rod length was to allow calibration of the wastegate but hot-rodders quickly figured out if they shortened the length of the rod, they could either restrict the amount the wastegate could open, or otherwise cause the cracking pressure to go higher (because of the additional preload on the spring). On the LUJ/LUV engine, indeed an adjustable length threaded rod is used between the WGA and the wastegate, but the factory attempts to prevent tampering by using some sort of locking compound on the threads. This isn't enough to stop a dedicated tinkerer, but we wholly recommend AGAINST modifying the length of this arm for the simple reason that it can cause the turbocharger to overspin which leads to either a failed turbocharger assembly, or a failed engine. LUJ/LUV WGA showing tamper-resistent compound on actuator arm adjustment Additionally, changing the WGA rod length will have no effect on the boost potential without corresponding tuning changes because the ECU will detect there's more boost than expected and simply respond by either commanding less BCS duty cycle, or closing the throttle. Introducing the Forge Billet WGA for the LUJ/LUV Forge is an aftermarket UK company that specializes in engineering and manufacturing aftermarket WGAs (among many other parts). They have developed a billet aluminum WGA for the LUJ/LUV engine (Forge part number FMACC14T). One of the fascinating features of their part is the mechanical cracking pressure can be adjusted through the use of interchangible springs. Through our testing process, we found their part to be incredibly consistent from unit to unit (unlike the OE WGA) and of high quality. Forge Motorsport FMACC14T w/ “Yellow” spring pre-installed When you purchase this WGA from Forge, off the shelf it includes a “green” spring pre-installed in the WGA. We found this spring to be too “light” - in other words, the cracking pressure was actually LOWER than the OE WGA. We tested the next heavier spring, which is the “yellow” spring, and found it to be a suitable choice for the LUJ/LUV in that it allows boost pressures to reach the potential of the engine and OE turbocharger closely. We could have, of course, chosen an even heavier spring (such as the “red” spring). However, there is a trade-off using a heavier spring that needs to be recognized. Not only does the heavier spring weight raise the cracking pressure of the wastegate (e.g. the MAXIMUM potential boost level), but it also, in effect, raises the MINIMUM pressure that can be made from the turbocharger when 100% of the pressure is being sent to the WGA (e.g. 5% duty cycle). The OE WGA has a minimum of around 5psi of boost, but the Forge WGA with the “yellow” spring is closer to 12psi. We chose the “yellow” spring because it's the lightest spring that can allow the maximum boost potential to be reached which in turn raises the mininum boost by the lowest amount possible. If the minimum boost level is raised too far, it can cause a clunky driving experience, because the ECU will have to manage the torque by closing the throttle blade instead of being able to open the wastegate. Forge Motorsport WGA installed on LUJ/LUV turbocharger So, what about the power? We recently performed a series of tests on one of our development vehicles. It is a 2016 Chevrolet Sonic LT, with the LUV engine, and a manual transmission. It has the following modifications: 60 lb/hr fuel injectors RacerX cold air intake SPEC billet aluminum flywheel WaveTrac Limited Slip Differential (LSD) TRIFECTA calibration Out of the LUJ/LUV vehicles we have at our disposal, this one was closest to stock configuration, and the few modifications it does have would not materially affect the power output, except for perhaps the flywheel. As expected, on the stock calibration (adjusted for the 60 lb/hr fuel injectors), this vehicle baselined at fairly high numbers on our dyno: Peak power output was 135 horsepower (HP) at the wheels (WHP), and 151 lb-ft torque (TQ) at the wheels (WTQ). Considering this vehicle is rated at 139HP / 149TQ at the flywheel from the factory, it would seem indeed the aluminum flywheel had a positive impact on power output for this vehicle. TRIFECTA Calibration with the OE WGA As started above, we consider 22psi (at sea level) to be the highest boost level that can be achieved on the OE WGA. This dyno chart shows what 22psi on this vehicle produced versus the OE calibration: Under these test conditions, PEAK gains went up by approximately 26WHP and 47WTQ. However, particularly with horsepower levels after the curve, gains are much higher than 26WHP – e.g. at 6300 RPM, the gains are closer to 45WHP. High RPM power delivery holds much further into the high RPM range than on the OE calibration. TRIFECTA Calibration with the Forge WGA and “Yellow” Spring Finally, we tested the vehicle and calibrated it to its full potential with the Forge WGA. Observe the following dyno chart: Versus the OE WGA, we gained another 17WHP, and a whopping 33WTQ! The torque gains are so impressive because this engine can really utilize boost levels higher than 22psi at the low to mid RPM range. Choosing some key RPM points, the following table summarizes the gains that were possible with just tuning and the Forge WGA: 3500 RPM 5500 RPM 6000 RPM 6300 RPM OE WGA / Calibration 146WTQ 133WHP 123WHP 115WHP OE WGA / TRIFECTA (22psi) 190WTQ(+44) 155WHP(+22) 143WHP(+20) 141WHP(+26) Forge WGA / TRIFECTA 229WTQ(+39/+83 total) 166WHP(+11/+33 total) 157WHP(+13/+33 total) 156WHP(+15/+41 total) More than just Power Believe it or not, the vast majority of calibration work required to make the Forge WGA work correctly has nothing to do with getting the big power gains. Because the turbocharger response from the BCS was dramatically altered with the installation of this part, we needed to start from scratch in dialing in the BCS table and the other PID controller constructs. We've spent about a week of total time on the dyno with various LUJ/LUV vehicles just getting everything mapped correctly. Without proper calibration work, people installing this sort of part are likely to have sporadic, or even common issues with “boost limp mode”. This is where the ECU detects that there's been an ongoing boost control problem for long enough that it shuts down the boost control system entirely. This results in a maximum boost level of about 12psi (or 5psi on the OE actuator) and a very powerless vehicle! - TRIFECTA Performance

    TRIFECTA: Big Turbo (EFR7670) + 2.0L LTG = 500WHP

    The LTG Engine Introduced in 2013 with the then-new Cadillac ATS, and also in the “Gen 8” Chevrolet Malibu, the “clean sheet” redesign of GM's “large” 4 cylinder turbocharged engine, the LTG engine was one of the most exciting developments to come along from GM! The LTG engine basically shares nothing in common with the outgoing LDK / LHU 2.0L turbocharged engine. It's so radically different, in fact, that the engineers changed the direction of the head flow on the LTG as compared to the LDK/LHU. LNF Engine in Cobalt SS On the LTG engine (in a front-wheel-drive application), the intake ports face the firewall, and the turbocharger faces the radiator. This is “backwards” from the flow of the LDK/LHU. In our opinion, this decision makes sense, because the turbocharger can benefit from airflow from the front of the vehicle in this configuration (ironically though, the LTG's successor, the LSY engine has reversed the head flow back to the same configuration as the LDK / LHU). LTG Engine in Camaro Aftermarket Development The unfortunate part about a “clean sheet” redesign is it frequently antiquates most or all investments the aftermarket might have made in similar engines. For example, by the time the LTG arrived and the LDK / LHU was beginning to be phased out in production vehicles, there was an extensive aftermarket parts market for these earlier engines (particularly the LNF, of which the LDK / LHU derives from). But almost none of those parts could be used to modify an LTG engine. Fastforward six and a half years from the time the LTG vehicles arrived on the market, and now there's quite a variety of parts in the aftermarket! Everything from intercoolers, intake systems, to turbocharger upgrades, and fueling upgrades (injectors, pumps, etc.), and it's shaping up to be a very exciting time for the LTG! Big Turbo TRIFECTA has been working on a Borg Warner EFR 7670 swap for the RWD Alpha chassis vehicles for some time. The most recent official dyno numbers we've seen on a 2017 Camaro with the 8sp automatic transmission is about 470WHP, but unofficially we've seen as high as 490WHP, on 92 octane pump gas. Big Turbo Camaro on the dyno This swap kit includes an integrated exhaust manifold that is one piece, from cylinder head, to turbocharger turbine. The exhaust side is located to OE coordinates, and the exhaust flange is the same as the OE LTG turbo exhaust flange. Existing exhaust components can be used with this swap kit. Factory turbo vs EFR7670 turbo The swap kit retains the electronically controlled bypass valve, and features a high pressure integrated wastegate. At this power level, we are using aftermarket camshafts with a “fuel pump lobe” to stretch the capacity of the OE high pressure DI (direct injection) pump. How about some E85? Any guesses on where the power will go with E85? We've installed upgraded fuel system components to help support the additional volume of fuel we'll need to run E85, maybe we can reach 550WHP, or maybe even 600WHP! Upgraded High Pressure Fuel Pump Stay tuned!

    Tuning Buick Regal's Sport and GS Mode - Beta Calibration

    TRIFECTA Exclusive Driver Selectable Vehicle Modes (DSVM) One of the earliest exclusive TRIFECTA product features is DSVM, formerly known as Select-A-Tune (SAT). Taking root in the days of the first 2.0L turbo DI engine GM built (RPO: LNF), SAT was a feature designed to give the driver dynamic control over the vehicle's power output. This feature was a very popular distinguishing feature of the TRIFECTA calibration. Over time it evolved into DSVM by name, and has been implemented in most vehicles that TRIFECTA offers a calibration for. DSVM and SAT are exclusive because they rely on the specific software that doesn't exist in the OE software. Some vehicles have OE DSVM-like capabilities, such as the 2014-2019 Chevrolet Corvette, but many other vehicles do not. Buick Regal GS and Sport buttons TRIFECTA has always been interested in whether either (or both) the GS and/or Sport buttons found in the Buick Regal could be tapped into to change the engine's dynamics on the fly. After some amount of research we determined that these buttons can in fact be used to select alternate automatic transmission shift profiles, but selecting alternate performance envelopes and pedal response maps seemed to not be possible with the OE software. Bringing DSVM to your Buick Regal GS and Sport button TRIFECTA is proud to announce we are opening a limited beta program for existing and future TRIFECTA customers that would be interested in being able to change the power and drivability dynamic of their Buick Regal on the fly with the GS and/or Sport button! If you have a 2014 Buick Regal, or a 2015 Buick Regal with either (or both) the GS and/or Sport button, and you would like to try this new feature, please contact us via our support system and request the “Buick Regal DSVM Beta test” and let us know which button(s) your vehicle is equipped with! Our engineers will put together a beta test calibration for you, and post it to your download page. After that you can install it, and provide feedback on how you like the drive modes! Contact Us!

    Serving the Community First, and Continuous Improvement

    Background A TRIFECTA Chevrolet Equinox calibration customer of about a year contacted us about his other car, a Chevrolet Cruze which was tuned by another company. He stated he was having issues with it going into “limp mode” under various conditions and setting various diagnostic trouble codes (DTCs). After some discussion, we learned he was within a few hours' drive of one of our R&D centers, so we offered to investigate the issue for him at no charge, as a courtesy. Full Vehicle Inspection One of the concerns we have when challenges like this arise is the breadth of issues that might have arisen on the vehicle. This is a vehicle that's over 5 years old, and has around 100,000 miles on it. It's been modified, and has unusual issues with it. So, we told the gentleman that the first thing we were going to do is perform a full inspection on the car, on a lift to look for anything that might be causing or contributing to the issues and if we had any reservations based on what we discovered whatsoever, we may not be able to proceed. This car turned out to be in excellent condition for its vintage. The only issue we found was a slight oil leak on the oil pan, but overall it was in very good condition and had been well maintained. Data Collection After passing the inspection, we put the car on the chassis dyno to observe how the current tune on it was running and what was going on with it, but before doing so, we checked to see how the wastegate actuator was set up. This aftermarket part is adjustable, and if adjusted incorrectly for how the calibration is written, it can cause boost control errors (overboost or underboost) which generally leads to “limp mode”. After confirming the wastegate actuator required no adjustment, we proceeded with studying the vehicle's operation on the dyno. Here's the full dyno pull: Our general consensus was this is a decent tune – power delivery was smooth, good AFRs, no knocking, etc. However, we discovered that the ECM was closing the throttle blade because the turbo was generating more boost than it was supposed to (overboost). This caused a power drop (see red circle). After further study of the data from the vehicle under various operating conditions, we found it had a general overboosting problem and suspect this was at least a contributing factor to the “limp mode” issues the vehicle owner had experienced. Starting from Scratch Our commitment to the vehicle owner was that, if both, after the vehicle passed inspection, and after reviewing the data we felt it was something we might be able to fix in the calibration, we would start over from scratch with the TRIFECTA production calibration for this vehicle, work to confirm proper boost control with the wastegate actuator, and then see where we could go with it power-wise with our margin of safety and reliability in mind. Here's what the production TRIFECTA calibration vs the tune it came in with (red vs blue) did with the wastegate actuator settings incorporated, but the power level settings set for the stock wastegate actuator: The TRIFECTA production tune carried the power further into the power band at higher RPM, delivering an almost 8 horsepower at the wheel (whp) gain, but had lower torque and horsepower output because it was calibrated for the OE wastegate actuator. Dialing it In Remember, the original issue the vehicle owner had wasn't with the power. It was with the fact it was going into “limp mode”, so our goal wasn't immediately to shoot for the moon on power. Rather, it was to determine if we could get the boost control accurate enough so we could be sure the vehicle would behave correctly if everything is in working order. We had previously spent a solid week on the dyno (and much more testing under regular driving conditions) with our own vehicles to develop TRIFECTA support for the Forge wastegate actuator with the yellow spring (and its derivatives), so we had a proven calibration to start with. There had been some concern that the wastegate flow characteristics on this vehicle weren't entirely the same as some of the other vehicles with the same engine. As such, we did notice some subtle overboosting at 50% pedal, on the dyno, even with our wastegate actuator settings: The green line (actual boost pressure) should always be below, but near the blue line (desired boost pressure). As you can see here, the green line was slightly above the blue (indicating an overboost condition), particularly near the end, just prior to the blue and red (manifold absolute pressure) lines drop off, which is where the pedal was released. The overboost is only about 13kPa here, but given overboosting was a primary concern for the vehicle, we made some adjustments to get the green line below the blue one (this is a full dyno pull): There is still a very slight overboosting on spool up, but that is considered acceptable by the ECM. After that, you can see the green line stays right on or slightly below the blue line now. No more overboost! The Dyno is One Thing, the Street is Another A chassis dyno is an incredibly useful tuning tool, and the dynos that have the eddy current loading system are even more invaluable for simulating various load conditions. However, street testing is crucial, and with an issue like this where the vehicle “limps out” under various conditions, the street testing is, in reality, even more important. So, we took the car for an hour long drive on the street. Residential areas, highways, downhill, uphill, corners, driving lightly, driving aggressively, winding the RPMs out, lugging the engine, everything we could to test out our boost control settings. Not once did we encounter a “limp mode” event. Having declared the wastegate settings correct, we moved on to the next step! Shooting for the Moon Now for the fun part! By now we were convinced the boost control was correct on the car, so we decided to see what we could do power-wise with the setup. By making some power limit adjustments that could take advantage of the upgraded wastegate actuator installed on the car, we made some really nice improvements in power over both the tune it arrived with and the TRIFECTA production calibration! See here: As a refresher, blue line is the tune the car came in with, red was the TRIFECTA production calibration, and green is the TRIFECTA production calibration plus tweaks for the upgraded wastegate actuator (which the tune the car came in with had also). There were improvements in every part of the power band, with the various hightlights: Spool up RPM (2000-3200 RPM): +10 lb/ft torque up to +22 lb/ft torque Peak Torque RPM (3650 RPM): +16 lb/ft torque Peak Horsepower RPM (5700 RPM): +22 horspower Happy Customer, Good Times The vehicle owner was very pleased with not only the power gains, but also that we had simultaneously resolved the “limp mode” issues to a large degree and introduced a new quality of refinement and smoothness to the way the vehicle drives on the street. Time will tell if it's truly resolved, but we will continue to actively follow up with the vehicle owner and collect additional data as needed. This was also a rare opportunity to meet a member of the Cruze car enthusiast community we consider ourselves proud to serve. We ripped around in the car, had lunch, traded ideas for car modding, joked about life in the automotive business, and just plain old had a good time. Continuous Improvement We regard every opportunity we are privileged with to work with customers directly an opportunity to improve our knowledge, experience and calibration techiques. Thanks to the owner of this Cruze, and his familyfor taking the time to be involved in this project, we learned some things that we believe will lead to improvements in our production level products as well. Namely, we believe some (likely not all) of the gains we found as we optimized the torque and horsepower bands for the upgraded wastegate actuator may be possible to a certain extent on the OE wastegate actuator as well. And we learned how some of the wastegate ports can flow differently from one turbo assembly to another. Everything we learn along the way becomes part of the product updates we release in the future, to our customer base.
  9. We started with a 2017 Chevrolet Cruze hatch. We took the original engine and transmission out, and swapped in an engine and transmission from a 2017 Chevrolet Malibu Premier. This is the 2.0L turbocharged engine coupled with the 9T50 front wheel drive 9 speed automatic transmission. With proper calibration work, this engine and transmission in its stock form can deliver about 300HP at the flywheel. This equates to around 240HP at the wheels, which is about 70WHP more than the LE2 can produce with a proper tune. We didn't stop there, though. We also installed aftermarket cams to increase airflow and fuel pump supply. And we added our "T40" turbocharger, which produced darn near 400HP when we tested on a Chevrolet Malibu recently. We have an aftermarket front mount intercooler for tuned up 2.0T engines, a cold air intake, and a custom dual-outlet exhaust system. The challenges were many in building this car. Which axles to use? Which mounts? Where to move the radiator to make room for the turbocharger? The wiring! The engine may fit in this car like it was designed for it, but there couldn't be much more different with the wiring harness on the Cruze vs the Malibu. But, in the end, it all works, as if Chevrolet themselves built the car. You push the start button and the engine roars to life through the custom exhaust system with an aggressive yet tasteful note. It may seem like the little things, but it's the little things that matter: The gauges work. The heater works. The brakes work. Shift it into Drive, and you're off. The 9sp automatic transmission peels through the gears smoothly. Put the pedal down, and hold on. The car is a work in progress, there's still a few things that need to be done with it (like fabbing a bracket for the ECM instead of using zip ties lol), but make no mistake, the Cruze has entered a new age.
  10. Hey @Gun3214, This is an in-house development project designed to showcase what can be done with the Cruze, but also a learning exercise for us as there were many engineering and calibration challenges that needed to be solved along the way. As with any hardware project we undertake, we may always consider bringing a big project to market if there were sufficient demand for it!

    TRIFECTA: LE2 Engine - Intake Manifold

    Also, note there appears to be an internal PCV system like the Gen1, and also this intake manifold has a LOT of oil in it (this engine has less than 1000 miles on it). It makes us wonder if the oil ingestion has to do with the piston problems the LE2 has? Could a catch can help?

    Is TRIFECTA a "Canned" Tune? Not really...

    “Canned” tuning defined The clearest example of a “canned” tune is the off-the-shelf handheld programmer that you can buy at, say, the local autoparts store. This is a device that contains a pre-written tune for a vehicle (or many vehicles). Basically, you plug it in, the programmer reads out your OE calibration, makes changes to it, then writes (flashes) it back to the vehicle. In some cases, you may have limited options for adjustment, like to adjust the speedometer calibration for different sized tires. This type of tuning is generally designed for stock vehicles, or vehicles that have modifications that are compatible with the OE calibration. Benefits: 1. Easy to use 2. Low cost 3. Able to make limited adjustments 4. Great for “casual” tuning customers that want a performance boost without a bunch of hassle Drawbacks: 1. Can't support major modifications out of the box** 2. Tuning is generally more conservative because of vehicle to vehicle variances 3. The engineers that developed the calibrations may have more generalized tuning expertise 4. Little recourse if the vehicle doesn't operate properly for some reason “Canned” tunes are generally considered “mass market” in that they appeal to a wide variety of customers. They are generally less expensive than “customized” tuning, and easy to install by the end customer. However, they are largely for stock or lightly modified vehicles (e.g. you're unlikely to find an off-the-shelf programmer that has built in support for an aftermarket cam in your Corvette). In designing a “canned” tune, one has to consider the range and condition of vehicles it might be run on, and this means the tuning “aggression” may be lower. Calibration engineers that develop these calibrations may have a more general set of tuning skill as opposed to expertise in a specific vehicle. Lastly, what do you do if the vehicle doesn't run right, or has a problem? About the most you can do is uninstall the programmer and return it for a refund or sell it to someone else. ** - some of the programmers on the market can also receive customized tuning from network tuners “Customized” tuning defined “Customized” tuning, on the other hand, involves the iterative process of making tuning changes, collecting data (via “datalogging”, wideband, dyno, etc.), and then making further adjustments until the calibration is deemed “complete”. This process involves the use of commercially available calibration software to make the iterative changes. The process is executed either by an end customer with tuning expertise or by enlisting the services of a “tuner”. Benefits: 1. Capable of supporting almost any modification the tuner has expertise in 2. Tune can be “individualized”, or “dialed in” for a specific vehicle in a specific locale 3. Higher level of customization is possible (virtually any parameter can be customized) 4. Comprehensive performance data can be available Drawbacks: 1. More expensive (up to 4-5 times), more time consuming, may need “retuning” later 2. No common standard of quality in the end product 3. Limited by the capabilities of the software being used 4. Tuning process may include elements that aren't understood by the tuner The “customized” tuning process generally happens one of a few ways. One way is a customer brings a vehicle to a performance shop for a “dyno tune”. Another way is a customer meets up with someone locally who has the tuning software. The third common scenario is “remote custom tuning” where the customer works with a tuner in a remote location, generally over the internet to go through the iterative tuning process. Most “heavy modifications” like forced induction conversions (e.g. supercharger or turbocharger kits), camshaft changes, or other engine internal changes require extensive recalibration in order for the vehicle to operate properly. Many of the larger forced induction kit manufacturers include some sort of calibration for the kit (and in some cases it may even carry a CARB EO number). A performance shop may install the kit, the calibration, then “dial it in” as needed. In other cases the performance shop may have to tune the kit from scratch, starting with the OE calibration which can be time consuming. In almost every case, with “customized” tuning, the tuner has greater access to tuning customization because in theory any parameter can be modified with the software. With an off-the-shelf programmer, for instance, you might be able increase the transmission shift firmness in a general way, but with a “customized” tune you can be more specific and adjust the shift firmness only on the 2-3 shift at part throttle. And, because the “customized” tuning process relies on iterations of data from the vehicle (which may include chassis dyno results), there's more information available about how the vehicle is performing. However, because this process is iterative, it also means it can be time consuming for both the end customer and the tuner, because the vehicle needs to have data recorded from it as part of the iterative process. In the context of a “dyno tune”, dyno rates are generally assessed by the hour and can be upwards of $300/hr just for the dyno time. On top of that you have software licensing costs. Most of the commercially available calibration packages charge a per-vehicle license fee, which, in extreme cases can exceed $600 / vehicle (e.g. if ECU unlocking services are required). And, tuners don't work for free – in many cases they charge an hourly rate as well. A full “customized” tune can easily cost upwards of 4-5 times what an off-the-shelf programmer might cost. The biggest drawback to the “customized” tuning process is that there's no common standard of quality – in other words, there are some really good tuners and there are some who are tuners simply by virtue of owning a laptop and the tuning software. There's also the issue of tuners being proficient on one type of vehicle, and the opposite on another. Anybody with a laptop and a few hundred dollars can become a “custom tuner”, and some of these tuners associate their competence with the software they are using as a common brand rather than the actual quality of their end product. The companies producing the calibration software don't really take any action to make a distinction here, but at the same time they cannot enforce a common standard of quality, they're just producing a tool that other people use, and in some cases the tool is incomplete. As anybody who deals in knowledge and information as a trade, it's expected that there's some level of 'mysticism' around how a tuner knows what they do and where they learned their techniques from. Aside from their personal experience, this can come from many places including tuning schools, training materials, online discussion boards, discussions with other tuners, reverse engineering of other tuning products or studying tunes from other tuners. Sourcing knowledge this way without fully understanding the “how” or “why” can allow unknown and potentially undesireable artifacts to get into an end customer's tune. The other issue is that a “customized” tune is completed at a specific point in time, under specific conditions (vehicle, environment, etc). For a customer that stays within a specific locale and only drives their vehicle under similar conditions (e.g. seasons), this may not be an issue, but does the tuner know how your vehicle is going to perform in the middle of winter at sea level if they “custom” tuned it in the middle of summer at 4000 feet altitude? The larger kit manufacturers that provide a calibration with, say, their supercharger kit probably do, but a tuner at a dyno shop probably doesn't. If there are problems with it in different environments, it may be necessary to perform follow-up tuning adjustments which is time consuming, and potentially disruptive to the end customer. Finally, there's no guarantee the software tools being used for this process are complete and provide access to all the constructs in the ECU required to properly calibrate the vehicle. In fact, there's no guarantee even the OE software that runs in the ECU has all of the necessary constructs to properly support the calibration of a heavily modified vehicle. E.g. the software engineers that wrote the ECU software for a naturally aspirated Corvette would not have put much consideration into what would happen if the aftermarket installed a supercharger. TRIFECTA tuning, defined Ok, so we have defined “canned” tuning, and “customized” tuning. Where does TRIFECTA fit on the spectrum? It turns out TRIFECTA products borrow from the advantages of each while offering other advantages that don't come with either type of tuning. Advantage: Pricing TRIFECTA products, in most cases, are priced to be competitive with off-the-shelf “canned” programmers. These programmers are lower cost because the manufacturers of them are not directly subject to the per-vehicle licensing fee like the “customized” tuners are, and there's no tuner looking to monetize the service. They also benefit from economies of scale. TRIFECTA similarly enjoys a low overhead because all of TRIFECTA's flash software was written in-house, is not reliant on any 3rd party, and as such is not subject to expensive licensing fees. Advantage: Ease of Use, little hassle TRIFECTA products are installed using a Windows based laptop combined with a USB cable that interfaces with the vehicle via the OBD-II port. This is also how most “customized” tuning software works as well. The ease of use advantage is that with TRIFECTA, the calibration work is already done. There's no learning curve for how to use a calibration software package, you just install a simple Windows based application, load the calibration, and you're finished. Advantage: Expertise, on your vehicle TRIFECTA doesn't offer tuning products for vehicles they haven't exhaustively calibrated and spent significant amounts of time with. Many other companies in the industry will ask for “R&D vehicles” from the market, or even experiment on customer vehicles as a generally accepted procedure while TRIFECTA makes an enormous investment in having a fleet of vehicles for ongoing campaigns. We share engaging content of these vehicles through the web and social media. Advantage: Support for modifications, small and large TRIFECTA has an aggressive directive to build a knowledge base of support for aftermarket modifications. Again, while retaining an appealing price-point, TRIFECTA can and does also support modifications that, through any other tuning company, would have to be supported through “customized” tuning. Need a tune for that custom aftermarket sheet metal intake for your Chevrolet Cruze? No problem, we've got you covered. Advantage: Tuning products can be “individualized” or “dialed in” if needed Many TRIFECTA products offer an Elite tier. This is a higher priced tier that provides “remote customized” tuning support for parts we may not have an off the shelf calibration for. TRIFECTA's team of calibration engineers has vast experience in virtually every type of modification out there and allows customers to leverage this knowledge through the Elite tier. Advantage: If you do have a problem, we've got you covered TRIFECTA offers products at the price-point of a “canned” tune but provides diagnostic services, knowledge, experience, and capabilities that can rival factory-authorized service centers. In the majority of cases, if there's a vehicle that isn't running correctly, it's because there's a problem with the vehicle (though in some cases software incompatibilities can reveal issues that need to be resolved at the tuning level). That doesn't mean you're out in the cold, though. Regardless of what product tier our customers have, TRIFECTA provides full diagnostic services and support as needed to help track down the issue, whether it's vehicle, software, or tuning related. Advantage: We abuse our cars on the dyno, drive them across the country Can your tuner claim and prove they put several hundred dyno pulls on their Cadillac ATS-V then drove the car across the country through various climates and environments before selling you a product? TRIFECTA can. The aggregation of the data gathered from this type of process makes our products more thorough. Advantage: Common standard of quality Our calibrations are developed by the same engineers, with the same processes and level of experience. When you buy TRIFECTA, you're buying a standard of quality you can't be assured to get from any arbitrary tuner that promotes themselves by saying they use the same tools as other tuners do. Many “customized” tuners learn by tuning other people's vehicles. Is yours the first? Second? TRIFECTA has been in the industry for nearly 15 years (at time of writing). Advantage: Innovation and exclusive features These are some of the exclusive features that TRIFECTA offers that can't be had anywhere else, and in some cases that's because these features don't even exist in the OE software. TRIFECTA approaches performance and reliability from a holistic standpoint and will add exclusive features where it makes sense from a customer demand or reliability standpoint. Driver Selectable Vehicle Modes (“DSVM”) - changes the performance level or drive feel on the fly with the cruise control switch Power-by-Mode (“PBM”) – An extension of DSVM for select platforms with factory drive-mode selectors, we can assign different power levels to each mode, as well as change driving characteristics (pedal feel and shift strategy): e.g. ATS-V Tour: Stock power, stock shifting Sport: Moderate power increase over stock, performance oriented shift strategy Track: Full power, performance oriented shift strategy Advanced Rail Pressure Management (“ARPM”) - Dynamically adjusts airflow limits based on the DI fuel system saturation level 2017+ Transmission Recalibration (“T87A”) – We can recalibrate your “T87A” controlled transmission (8, 9, 10-speed) without removing the TCM, let alone paying for an expensive unlock procedure. Performance AutoStop Mode (“PASM”) – Allows the driver to enable a performance-oriented auto-stop mode which, in most cases, inhibits auto-stop from enabling for improved performance character, when desired (triggered by the cruise control arming button) AutoStop Deletes - A new product line that simply disables the factory “autostop” feature! Introduced as a fuel-savings feature, “autostop” allows the vehicle to shut the engine off when the vehicle is stopped, and quickly restart it when the driver is ready to move the vehicle, but not all vehicle owners feel it works smoothly enough. Advantage: Continuous innovation and improvement “Customized” tuning is largely a one-time deal. You get tuned, that's it. There may be minor adjustments as needed, but there's no real infrastructure in place to give out “mass updates” that make improvements to customers. Because of this, and frankly the lack of a financial aspect, there's little incentive to put a dedicated focus on innovation and improvement. TRIFECTA views continuous innovation and improvement as core tenets of business. The Chevy Cruze launched in late 2010 - at the time of writing that was over 8 years ago. To this day, we still have an active campaign to improve the feature-set of the product and we make these improvements available to every customer. Disadvantage: Can't use commercial tuning software to modify TRIFECTA On the surface, some may feel this is a “vendor lock-in” strategy. That might be the case if we didn't provide a means to uninstall the product and restore the capability of it to be used with other tuning software or OE updates – but we do. At the time of writing, the commercially available tuning software packages require the vehicle to have either completely OE software, or a modified derivative of OE software. A TRIFECTA tuned vehicle is neither, but can easily be restored to OE software using our tools. Disadvantage: TRIFECTA's bar is high for supporting aftermarket modifications While our “remote custom” tuning services give our engineers the tools to tune virtually any build remotely, consideration is given to whether we can do it in a timely manner and smoothly for the end customer. The only thing that's worse than declining to tune a project for a customer is accepting the project (and customer's money), and then not being able to deliver a quality tuning product in a timely manner. We believe expectations need to be set appropriately and being able to deliver quality is more important than selling a calibration to a customer. Disadvantage: TRIFECTA's data logging format is proprietary (like everybody else's) TRIFECTA's flash utility can also generate “data logs” from customer vehicles, but the data is stored in a proprietary format - in the same way other commercial tuning software uses a proprietary format. In fact, it's considered a modern computing security concern to use a proprietary format to protect the authenticity of the information being transmitted. Unlike other software, however, we do not provide a public viewer for this data, and rely on a series of non-public tools to process the log data. Having said that, data logging of a TRIFECTA calibration can still be performed using any tool that supports data logging the vehicle, though, and we can provide recommendations that are compatible with our flash cable for customers that wish to review the data from their vehicle as well. Conclusion We're not here to say that TRIFECTA is a perfect fit for every tuning situation, because we aren't. The goal in this writing is to put some definition around the terms sometimes used to describe our products. On the surface we do look like a “canned tune”. We're priced like one, we provide many of the advantages of one, but we also bring to the table many of the advantages of “customized” tuning. But, in the end, the intersection of these benefits combined with our exclusive features and offerings put TRIFECTA into a class of its own.

    Changing the injectors on the LTG engine isn't as straightforward as changing injectors on most MPFI engines. As you can see, we had to remove the intake manifold to gain access to the fuel rail. Also note how much more "beefy" the fuel rail and injectors are compared to MPFI fuel rails an injectors. That's because SIDI injectors routinely have to operate in the 2000-3000psi range, sometimes beyond 3000psi even. That's compared to 45-60psi on most MPFI rails!

    Gen 2 Cruze turbo upgrade currently under development and testing!
  22. With roughly 20 minutes to spare, you can reprogram your Cadillac ATS-V to drive and perform even better than it did from the factory. Without changing a single piece of hardware, you can bring your 464HP sport sedan or coupe up to 600HP** (380HP up to 500HP as measured at the wheels on a chassis dyno), and give it a more sport-inspired drive feel. (** Estimated crankshaft horsepower based on calculated drivetrain losses) If you have a 2017 or newer Cadillac ATS-V with an automatic transmission, you do NOT have to remove your transmission control module (“TCM”, T87A) for any unlocking process. All TRIFECTA Cadillac ATS-V calibrations include extensive transmission strategy reworking. (2016 models use the "T87" controller, which also does not require removal from the vehicle) Why TRIFECTA? Why buy a tune from a dyno shop that might run your car on the rollers 10 times when you can buy from a company that's channeled over several hundred dyno pulls' worth of testing into their product? Rather than relying on a “dyno tuner” that may or may not have experience tuning the ATS-V (but almost certainly to their local area only), with TRIFECTA you can rest assured you're purchasing from the company that's been in the GM factory turbo vehicle tuning business longer than anybody else, in many cases pioneering the tuning aftermarket for these vehicles. The TRIFECTA ATS-V calibration has been subjected to over 300 chassis dyno pulls, on dynos across multiple continents, and tens of thousands of test miles have been accumulated in virtually every climate, elevation and season. TRIFECTA's calibration for the Cadillac ATS-V is also packed full of exclusive and innovative features to make your ATS-V experience even better. From reworked knock control logic and zoning, to active fuel rail pressure management, to adding full-boost launch control, TRIFECTA's engineering team delivers exclusive features that Cadillac didn't even consider. Key Features of the TRIFECTA Performance MY2016--2017+ Cadillac ATS-V powertrain calibration software reprogramming: Dyno-proven gains in power Using industry standard chassis dynamometers, TRIFECTA shows proven gains in torque and horsepower for your Cadillac ATS-V, using only the factory hardware: Telemetry-proven gains in acceleration Dyno sheets are great, but they only show power output. Using professional grade telemetry equipment, TRIFECTA has also established proven gains of up to 0.87 seconds in 0-60MPH acceleration profiles versus the factory calibration.** **traction limited by factory tire and pavement condition (generally dry, medium worn asphalt). Faster times achievable with R-compound tires on prepared surface. TRIFECTA Exclusive ATS-V Calibration Features TRIFECTA's Cadillac ATS-V calibration includes many features that are both desired, and exclusive to TRIFECTA's calibration: Standard Tour Mode (STM) The ATS-V offers several different drive modes from the factory such as Tour, Sport, Track and Winter / Snow / Ice modes. TRIFECTA's custom operating system modifications allow us to optionally (but included by default) offer Tour mode which limits horsepower and torque output to levels very similar to the factory levels. This feature is very useful if the vehicle is driven by others who would prefer the vehicle to operate like it does from the factory. Drive modes can be changed on the fly, and as such, the driver may select any mode, at any time. No transmission control module (TCM) “unlock” required General Motors, starting in the 2017 model year, began using a new transmission control module (“TCM”, called the T87A) for the 8 speed automatic transmission used in the Cadillac ATS-V. The T87A employs digitally signed programming segments to prevent transmission calibration reprogramming by parties other than General Motors. While there is an exploit to unlock the T87A to allow reprogramming by other parties, it requires physical access to the TCM (via removal from the vehicle), and an unlock procedure. However, TRIFECTA is pleased to announce this “hands-on” exploit is not needed for the TRIFECTA Cadillac ATS-V calibration product. Extensive transmission strategy reworking is accomplished without “unlocking” the T87A. (2016 models use the "T87" controller, which also does not require removal from the vehicle) Active Rail Pressure Management (ARPM) Worried about DI (direct injection) rail pressure when turning up your boost? TRIFECTA's Active Rail Pressure Management (ARPM) engine control module (ECM) operating system customization allows higher boost levels to be achieved while actively monitoring the DI fuel rail pressure and reducing boost, if a drop in rail pressure is predicted, based on past and present operating conditions. To read more detail about ARPM, see our article: TRIFECTA: Active Rail Pressure Management TRIFECTA Full-Boost Launch Control (8-Speed Auto) Anybody who's tried to launch the automatic transmission Cadillac ATS-V has noticed it's near impossible to both hold the rear wheels from spinning and simultaneously build full boost at launch. TRIFECTA's Full-Boost Launch Control exclusive feature allows the application of the brake, and full accelerator to build up to 18psi of boost while keeping the tires from spinning. After releasing the brake, full power is instantly applied. While this is helpful for little more than a smoke show on the stock tires, with proper tires and track surface, much quicker launches can be achieved (this feature does not interfere with the factory launch control features, and these features continue to work as they did from the factory). TRIFECTA Bi-directional Enhanced Knock Control and Zoning Whether anybody wants to believe it, or not, “knock”, defined as noise detected by the knock sensors, is going to occur from time to time. Generally this occurs when there's a transient change in fuel quality, or operating conditions. While the factory's knock control constructs are advanced, they make certain assumptions about how, and in which direction to adjust knock factor when knock is detected. The factory knock control strategy on the Cadillac ATS-V uses one zone only, encompassing the entire RPM range, and engine load range. TRIFECTA's Cadillac ATS-V calibration utilizes six zones and allows for finer self-adjustment when dynamic timing adjustments are needed. Furthermore, TRIFECTA's enhanced knock control employs an “ongoing” strategy which retains learned knock factors even after the engine is shut down, and continues to use them the next time the engine is started. Bi-directional knock control allows the ECM to begin its knock adaptation in the middle of the timing adjustment map, rather than always assuming it's running “high octane” fuel and potentially exposing the engine to audible knock. Enhanced Engine and Transmission Response Let's face it, Cadillac did a good job making the Cadillac ATS-V fun to drive from the factory. That didn't stop our drivability engineers from making it even better. In Sport and Track modes, accelerator pedal response is improved, while also refining tip-in response. Transmission downshifts are progressive, as opposed to the “all or none” strategy the factory generally goes with. Lower gears are held to a higher RPM, so a downshift is not needed if the driver decides at the last moment to chase down and humiliate a European Exotic. Tour mode and Winter / Snow / Ice modes retain stock pedal response and transmission shift patterns. Support for Aftermarket Parts TRIFECTA was one of the first companies to bring the concept of comprehensive remote tuning to the mass market. If you have aftermarket parts, talk to us about adapting our calibration to support them!

    TRIFECTA: Introducing the big compressor-upgrade turbo available for your Gen1 1.4T. 58mm!

    91 octane is all that is needed, and in fact the car will run on 87 octane if needed. Power will simply scale down accordingly. This turbo will actually be packaged as a kit which will include 60lb injectors, giving you all the headroom you'd need for E85. Our ability to control fuel pressure via reprogramming the Fuel Pump Control Module (FPCM) negates the need for an upgraded pump as well. You can read more about our research into injector options and reprogramming the FPCM here:
