  3. @joeker12, we'll be sending out the first kits by or before the end of March, with a firm release date to follow. @mallenjackson, we won't be doing pre-orders, but we do have an internal "wait list" going, which we can add you to if you like. 👍
  4. Factory size s 45.9mm. We will be sending out the first 58mm kits by the end of Q1 2019. 👍 We're still working on this one, so wheel size hasn't been finalized, but it is most definitely in the works!
  5. Hi @joe1278, The EZ Flash User Guide contains step by step instructions, as well as screen-captured videos of the EZ Flash installation and flashing process recorded in real time: https://www.trifectaperformance.com/ezflash
  6. 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?
  7. 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:
  8. This will delay the launch of our turbo just a bit longer, we need to calibrate with the larger compressor, but we're expecting better gains over the 55mm turbo! Stay tuned!
  9. The 2019 model year for the Chevrolet Colorado and GMC Canyon is largely a “carryover” from 2017 and 2018 model year, with the 2017 model year introducing the “next generation” 3.6L V6 (RPO: LGZ) engine as an update of the previous 3.6L V6 (RPO: LFX) and the 8L45 8 speed automatic transmission. The TRIFECTA performance calibration for the 2019 Chevrolet Colorado and 2019 GMC Canyon is unchanged versus the 2017 and 2018 Chevrolet Colorado / GMC Canyon product. Below is a list of feature highlights (V6): Gains of up to +41 ft-lbs and +28 WHP under the curve (and +18 ft-lbs and +10 WHP peak on 91 octane) Full 8 speed transmission recalibration WITHOUT TCM removal and/or unlocking Three way Driver Selectable Vehicle Modes (DSVM): Sport, Eco, and Tow/Haul Support for aftermarket modifications and hardware Performance Active Fuel Management (PAFM) – no V4 transitions in Sport Mode (Ad+, Elite) Full restore-to-stock functionality included Product updates provided at no charge (includes support for OE software updates) To order your TRIFECTA performance recalibration for your 2019 Chevrolet Colorado or 2019 GMC Canyon, please visit our store: https://www.trifectaperformance.com/store/category/66-colorado/ https://www.trifectaperformance.com/store/category/150-canyon/
  10. The 2019 model year for the Chevrolet Sonic is largely a “carryover” since the 2017 exterior and interior update, with one key change: the 1.8L I4 (RPO: LUW/LWE) engine is no longer available. The TRIFECTA performance calibration for the 2019 Chevrolet Sonic and 2019 GMC Canyon is unchanged versus the 2012 through 2018 Chevrolet Sonic product. Below is a list of feature highlights: Gains of up to +51 ft-lbs and +44 WHP Full transmission recalibration (automatic transmission vehicles) “No Lift Shift” feature retains boost through performance shifts (manual transmission vehicles) Two way Driver Selectable Vehicle Modes (DSVM): Sport, and Eco Support for aftermarket modifications and hardware Full restore-to-stock functionality included Product updates provided at no charge (includes support for OE software updates) To order your TRIFECTA performance recalibration for your 2019 Chevrolet Sonic, please visit our store: https://www.trifectaperformance.com/store/category/125-14l-turbo/
  11. The manual transmission is the hard one to find, most dealerships won't carry them, and we couldn't find any new ones with the 1.4T and also a manual transmission.
  12. Hi @Michael Plummer, The units shown in the article were created for testing, but did not contribute any appreciable gain to power, nor did the packing in the resonators hold up to the heat after extended abuse on the dyno. We are looking into testing a unit with a different design.
  13. 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!
  14. An HSN** means that the part was installed and tested for correct functionality on a TRIFECTA development vehicle, with the TRIFECTA calibration product, and if any specific calibration changes are necessary to support or optimize it, these changes have been established and finalized. As such, customers wishing to install this part on their vehicle may do so under the Advantage line product and will not require any customization beyond, in some cases, a parts-specific calibration update. The following is the manufacturer's description of the product: (For full info, please see the manufacturer's website here: MPFab Intake System for 2011-2015 Chevy Cruze 1.4L Turbo) During our testing, we found this intake system to deliver accurate airflow metering with the OE mass air flow calibration meaning this intake can be used with our without a performance / custom tuning / calibration. We found the sound and the quality of the kit to surpass most of the other mass market intake systems available for this vehicle. Future or existing TRIFECTA customers interested in purchasing this product may be able to do so through TRIFECTA, please contact our support team for more info! **Please note: A Hardware Support Notification (HSN) from TRIFECTA is a statement that we tested the product with our calibration products, and in some cases may include performance data collected and/or ad-hoc comments on the product by TRIFECTA.

  15. Gen 2 Cruze turbo upgrade currently under development and testing!
  16. Some consumers choose to modify their vehicles, for many reasons. In some cases, it's to add or enhance function (e.g. a truck lift kit to provide better off-road clearance). In other cases, it's to customize the look of the vehicle (e.g. aftermarket wheels and tires, lowering suspension, etc.). And in some cases, it's to enhance the performance of the vehicle (e.g. aftermarket 'tuning', exhaust system upgrades, cold air intake systems). So, the question becomes: Is a vehicle manufacturer obligated to cover “warranty issues” on vehicles that have been modified with parts or software that were not designed by the manufacturer? The short answer is “yes, so long as the warranty claim is for a part which is shown to have a manufacturing defect.” However, given the increasing complexity of vehicle designs and the inter-dependence of cross-vehicle systems and components, it's getting easier for the manufacturer to claim that ANY modification could have wide-reaching consequences and lead to the failure of a part which is, in fact, not defective. We commonly joke about manufacturers denying a warranty claim because of the installation of aftermarket lug nuts, but here's an example of how a manufacturer might rationalize this: Let's say there's a wheel hub bearing failure. The vehicle is towed to an authorized service center, they inspect the vehicle and find there are aftermarket chrome lug nuts installed. At this point they could reasonably claim that the aftermarket lug nuts are not known to be manufactured to the same weight, and balance tolerances that the factory lug nuts use, and as such, their installation lead to unusual forces on the wheel hub bearing which lead to its “unnatural” failure. As such, the warranty claim is denied because there's a plausible theory as to how the bearing failure could in fact be due to the installation of an aftermarket part. It would be in the domain of the vehicle owner to prove the manufacturer's theory is false. The above scenario is assumed to be fictional, but this one appeared in automotive media in 2016: A customer buys a brand new Chevrolet Silverado pick up truck, and as part of the sales contract purchases an aftermarket frame lift kit for the truck, which is installed by the dealership. After he takes delivery of the truck, he drives it for some period of time, then the Service Airbag light comes on. He brings it in for service at the same dealership that he purchased the truck from and to the very service department that had installed the lift kit. The dealership refuses to fix the issue under warranty. The stated cause? The aftermarket lift kit caused changes in the way certain airbag sensors operate (because the suspension and frame geometry were modified), causing a false-positive condition in the airbag sensor diagnostics. In both of these scenarios, it would be difficult (and expensive) to push back on these assertions the manufacturer is making. At the same time, it also leads one to wonder whether the manufacturer ever engages in abuse of this power? At the end of the day, it's murky, because in some cases, vehicle owners are trying to stick the manufacturer with the cost of making warranty repairs to the vehicle that they almost certainly caused via modification, and in others the manufacturer is hiding behind the aftermarket parts argument to avoid making repairs to a legitimately defective part. In some cases, a dealership service department may even have incentive to refuse to honor a warranty claim when they could, by procedure, have it honored. The economics behind a dealership service department are not well known, but it is possible that service departments receive a different compensation rate from a warranty claim than they would from a direct-pay customer. The following scenario may illustrate this: The owner of a new (and warrantied) Chevrolet Cruze buys and installs an aftermarket intake system. He gets the vehicle tuned by an aftermarket company. At some point later, one of the pistons fails and replacement is required. The piston failure issue is a WELL known and WELL documented issue with this engine, and between the dealership and the manufacturer there would be almost no question that this failure is in fact because of whatever defect leads to the failure in the first place (which the manufacturer has made no formal statement on). However, instead of repairing this vehicle under warranty, the dealership instead effectively cancels the rest of the power train warranty and says the modifications to the vehicle are the cause of the failed piston. This vehicle owner now has no power train warranty left, and is on the hook to pay for piston replacement. Is this treatment justified? Or is it an abuse of power? Again it is murky. Dealership service centers are the “gatekeepers” in many cases to the policy of what gets fixed under warranty and what does not. They are the ones that may make the decision to look deeper (or the manufacturer may request it). When an obviously-modified Cruze comes in with broken pistons, whether its a known issue or not, the very fact the car is visibly and obviously modified may give cause to look into it deeper (or flat out deny the claim on the basis alone). If it's what appears to be a completely stock Cruze with broken pistons in the manner described in the technical bulletin, there's likely to be no question about it. The level of aggression the manufacturers might display in this regard is almost certainly related to the cost of the warranty repair. It's one thing for the manufacturer to be looking at having to replace pistons in a 4 cylinder engine, it's quite another to be looking at having to replace an entire V8 diesel truck engine because there's a connecting rod hanging out of the side of the block. As such, manufacturers have taken up certain countermeasures, some are known publicly, to identify when a vehicle has been tampered with, be it via hardware (parts), software (tuning) or some combination thereof. On top of that, there's been (as far as we know, unsubstantiated) rumors that manufacturers are even turning to social media to identify people who have openly discussed modifying their cars. Unfortunately, nobody in the aftermarket can ever be sure what tampering countermeasures are being taken by the manufacturer at any point in time, nor what countermeasures may be taken in the future. Nobody can be sure what “non official” countermeasures are being taken, either. A good example of this is GM's OnStar. Think of your vehicle as having a communications backbone, for all the ECUs to communicate with one another, as well as diagnostic tools and aftermarket flashing tools. The OnStar module can effectively operate as a bridge between your vehicle's network and GM's OnStar network in any location that the OnStar's connection to the network can be established (it operates over the cellular phone network). This means, on a technical level, at least, anytime an ECU in the vehicle is flashed, as long as the vehicle is active on the OnStar network, the manufacturer may know about it, and/or make a log of it. They may even know the contents of the flash itself. The above scenario is unproven, just a technical analysis of what's possible, but here's another one that shows to what extent countermeasures may be deployed. On the diesel truck engines, massive gains can be made in power with just tuning alone, mainly by changing the fuel rate and increasing the turbocharger boost. With the availability of low-cost commodity tuning software, one could recalibrate their diesel truck for about $500 plus the cost of a laptop computer. No training in diesel tuning is required. The unfortunate reality is that while it's “relatively straightforward” to make more power with tuning in your diesel truck, to do so reliably requires a much higher level of engineering skill, in some cases outside the scope of what the factory ECU software is even capable of. The manufacturer started getting suspicious when they saw all of these diesel truck engines coming in for warranty repair with melted pistons. Suspecting they might be caused by poor quality aftermarket recalibration, they devised a new technique for identifying whether the tuning had been tampered with. They added a new parameter to the transmission control module where it would record and “remember” the highest amount of torque the transmission was subjected to. How does this work? The engine control module has to estimate how much torque it's making mainly for the purpose of having the transmission shift with the correct amount of line pressure and also with regard to the traction control system operation. Every time the engine controller transmitted its estimated torque output to the transmission controller, the transmission controller would compare the value to the previous highest value, and if the new value was higher, it'd remember that one. The new procedure involved scanning this parameter out of the transmission controller if melted pistons in a diesel engine showed up at the service center. This number SHOULD never be higher than the factory specs of the engine, and if it was, it was considered possible evidence of tampering. The bottom line is there are upwards of 70 ECUs in modern day vehicles, and any one of them is capable of reading (and storing) information transmitted by other ECUs. Tampering “counter-countermeasures” of any type may afford some protection against abuse of power by an over-zealous (or morally impure) service center, but ultimately if there's some sort of suspicious vehicle component failure despite the lack of any evidence of modifications, the service center will almost certainly try to use social engineering to find out if the vehicle is or was modified previously: “Have you ever tuned this vehicle?” “Have you ever installed any performance parts on this vehicle?” “Our techs found some anomalous ECU data string widget constructs and say it was tuned.” “Are you Joe Smith on Facebook also?” Questions and statements like these put the vehicle owner in a potentially tricky situation. If it was modified, and they tell the truth, their warranty's probably gone and they're on the hook for repairs. If they lie about it, then they may have just committed fraud. Refusal to answer the questions at all may be construed as suspicious as well. The only true way to be sure the manufacturer power train warranty remains in effect for the full duration with regard to aftermarket modifications, is to not aftermarket-modify the vehicle. Not even the lug nuts. -TRIFECTA Performance, Inc.
  17. Figure 1 – Racer X Manifold for the 1.4L Turbo (RPO:LUJ/LUV) Summary We found, with appropriate recalibration, the Racer X Fabrication intake manifold increases power as measured on the dyno, by up to 12 horsepower as measured at the wheel. Torque output peak was unchanged, but did shift up the RPM band by about 200 RPM (e.g. it took 200 RPM more to reach peak torque). Figure 2 – Dyno sheet showing Stock vs Racer X performance Beyond the power gains, it is our opinion this product will be popular in this market because it also permanently and effectively addresses the PCV issues this engine is known for, provides a custom upgrade part (and look) for these vehicles, and also allows for future expansion, as there are several unused ports in the end of the manifold which could be utilized for additional instrumentation, or water, water/methanol, and/or nitrous injection directly into the manifold. Comparison to Ported Intake Manifold (OE) Prior to the arrival of the Racer X manifold, the only other intake manifold modifications that had been widely used were the porting of the intake runners of the stock intake manifold, the so-called ported intake manifold, and the PCV system modification. Figure 3 – Stock Intake Manifold with “air tumblers” The OE intake manifold has a restriction in the runner near the intake port. It is believed these are actually air tumblers and are meant to induce intake charge swirl for more efficient combustion. However, it is also theorized that these air tumblers reduce and restrict airflow when higher levels of airflow are introduced (e.g. turning up the boost, upgraded turbocharger, etc.). We had performed a preliminary test on a ported manifold versus a stock manifold several years back and saw negligible change in power on the dyno, but a possible loss of efficiency (more timing advance was required to maintain similar power levels to unported manifold). Ironically, while the effect is the ECM reports the power output level has increased due to the additional timing advance (despite a wash on the dyno), the loss of efficiency could be attributed to less efficient mixing of the air and fuel charge due to the lack of tumblers, but a more conclusive test is needed. Figure 4 – OE Ported Intake Manifold The PCV system modification addresses PCV system failures that are prevalent on this engine by utilizing an external, and more robust check valve for introducing PCV vapors back into the intake manifold. This is achieved by installing a brass fitting in the bottom of the PCV chamber in the intake manifold, routing the PCV vapors either to a throttle body spacer, or the brake booster fitting. Figure 5 – OE Manifold PCV Modification While both of these modifications are popular in the community, they are also considered do it yourself (DIY) modifications which require special tools and skill. At the time this test was conducted, we did not have a ported intake manifold available, but we plan to do a comparison to it in the future. TRIFECTA Calibration Support We are pleased to announce immediate and full support for the Racer X manifold for the GM 1.4L turbo engine in our full custom calibration tier (Elite). Additionally, we will offer a free update for any TRIFECTA customer of record on or before 05/31/2018, regardless of which product tier they purchased! Test Vehicle The test vehicle is a 2016 Chevrolet Cruze Limited LT, equipped with the 1.4L Turbo engine (RPO: LUV), and the six speed automatic transmission. The vehicle has approximately 18,500 miles on the odometer, and aside from the manifold is also equipped with a catless down pipe, cat less mid pipe, and K&N cold air intake system. There were no other pertinent modifications to the vehicle. “92 octane” fuel, considered premium unleaded in the Seattle, WA area was used for all tests. Figure 6 – Test Vehicle Test Procedure In order to keep the test results as accurate as possible, we tested both manifolds on the same day, on the same vehicle, on the same chassis dyno, back to back. We tested the Racer X manifold first, since we had installed it previously for calibration procedure. After performing several test “pulls” on the dyno, in manual 4th gear, we let the car cool down, installed the stock manifold, warmed it to operating temperature, and performed several test “pulls”. From the beginning of the test procedure, to the end, the ambient air temperature only changed about 2*F. The dyno used was a Dynojet 424xLC all wheel drive dyno equipped with eddy current load cells (but were not used for the test). The vehicle was operated in manual 4th gear for all test pulls. After the dyno brake was released, the vehicle was put in manual 3rd gear, run up to 20 MPH, shifted to manual 4th gear, then decelerated to 1100 RPM, and then a wide open throttle maneuver was executed. The vehicle was operated until 6200 RPM, and the dyno “pull” was concluded. Figure 7 – Test Vehicle on the dyno, with Racer X manifold Installation The installation of this manifold is fairly straightforward, but isn't 100% “reversible” (more on this later). The manifold has an optional PCV system “add-on”, but we couldn't see how this manifold could be installed without it, unless one chose to simply vent PCV gases to the atmosphere, or perhaps someone wanted to fabricate their own PCV solution. Installation requires transferring (from the stock manifold): 1. The fuel rail and fuel injectors to the new manifold, 2. The EVAP solenoid, and 3. The Manifold Absolute Pressure (MAP) sensor. The installation instructions also call for retaining the turbo bypass valve (BPV) control solenoid so the Engine Control Module (ECM) won't set the check engine light, but we chose to skip this step and devised a means of installing the manifold without the BPV control solenoid without any negative effect via the ECM calibration. While we say this kit isn't 100% “reversible” (more like 90% “reversible”) it's of little consequence, in our opinion, because it would be unlikely an end customer would want to, or ever go back to their stock intake manifold. It's not fully reversible, because it requires cutting of some of the hard plastic lines that route to the brake booster and the PCV vent to the turbocharger inlet in order to complete installation. Initial Test Drive Our test vehicle was equipped with the production TRIFECTA Advantage calibration. On the first test drive, we noticed two issues with the vehicle, one was a hesitation and “dip” in power, in some cases accompanied by audible spark “knock” in the 5000 RPM range under full acceleration, and what seemed to be a somewhat laggy pedal response. While the manifold manufacturer states the manifold will work without issue on the stock calibration, it was clear to us that some additional calibration work would be needed for vehicles that have a more powerful aftermarket calibration. One net effect of using this intake manifold, which sports a larger intake plenum volume than the factory intake manifold is that actual manifold pressure levels end up lower than stock (while moving a higher amount of airflow due to flow and efficiency improvements). These changes in airflow and pressure dynamics showed us more in depth recalibration would be required. Dyno Calibration Session We spent most of a full day addressing the vehicle performance issues we had noted previously (the most time consuming being the full recalibration of the wastegate duty cycle table). We were able to resolve all of the performance issues and were able to regain the throttle response we experienced with the stock manifold. After completing the dyno calibration session, and resolving some minor calibration issues with street testing, we put approximately 1000 miles on the vehicle as a short term reliability test. No further issues were experienced. Airflow and Pressure Statistics When we performed the final back to back test on the dyno with the Racer X manifold vs the stock manifold, the following airflow and pressure statistics were observed: Airflow (mass air flow sensor) lb/min, 6020 RPM and Manifold Absolute Pressure: Compressor inlet pressure: 98 kPa RacerX: 18.55 lb/min, 211 kPa (113 kPa, 16.385 psi boost) Stock: 18.32 lb/min, 227 kPa (129 kPa, 18.705 psi boost) At 6020 RPM, in both cases, maximum pressure is obtained from the compressor. However, despite the manifold being at almost 2psi less boost pressure RacerX vs stock, the airflow is still higher, which is a more accurate measure of performance. We also sampled the data at 5500 RPM, the airflow differences were more pronounced (with similar manifold pressure): Compressor inlet pressure: 98 kPa RacerX: 18.62 lb/min, 229 kPa (131 kPa, 18.995 psi boost) Stock: 17.52 lb/min, 225 kPa (127 kPa, 18.415 psi boost) Conclusion Our testing has shown this product increases power, addresses several long-term issues with this platform (PCV system issues) all while offering a unique and customized look to the enthusiast's Chevrolet Cruze or Chevrolet Sonic! We believe it will continue to be a popular choice for people seeking the best for their vehicle!
  18. 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.
  19. Initial testing puts this on par with a tuned LE2, and will cost a heck of a lot less than it would cost to trade up to one. Stay tuned as we move forward on this project!
  20. It's common knowledge that the Corvette, going back to the mid 2000s has offered an exhaust valve option (RPO: NPP). In 2014, when the Chevrolet Corvette Stingray (C7) arrived, it included dual mode exhaust valves as standard equipment, as well as a set of "AFM exhaust valves" to help reduce the odd exhaust notes when the engine runs in 4 cylinder mode. When the 6th Gen Chevrolet Camaro came along, the dual mode exhaust valves became standard equipment on the SS and ZL1, and optional equipment on the V6. These exhaust valves are designed to stay closed during normal driving operation to meet federal noise standards, and essentially bypass the mufflers under hard acceleration for maximum performance. In Track mode, on the C7, the valves are designed to stay open all the time. The exhaust valves are controlled by the same ECU that controls the fuel pump pressure on the Chevrolet Cruze and Chevrolet Sonic. In fact, we found that the Camaro SS CCM is connector-compatible with the Cruze CCM! With a bit of wiring, and some software work in the CCM, retro-fitting exhaust valves on the Cruze / Sonic might be possible. Of course, the question is, how would one set up the exhaust valve? One idea we have is to T the single exhaust near the rear of the car into two pipes, one going through a standard muffler, and the other, through an exhaust valve, to a straight pipe out the back (or a cut out). Just one of the innovative projects TRIFECTA has on the horizon for 2018!
  21. Old School Fuel Injectors Ironically, the relatively modern LUJ/LUV uses the relatively old-school “EV1” style fuel injector connector. As such, aftermarket fuel injector choices are somewhat limited unless costly harness adapters are used. Bosch “Green Giants” 42# Fuel Injectors These fuel injectors have been popular in the aftermarket for some time. This a very good, general purpose fuel injector for the 1.4T engine, because they're not so large that they cause injector misfire or over fueling problems at idle. They are available with an “EV1” style connector, so harness adapters are not necessary. They are large enough to support full E85 on the stock turbo, and mild turbo upgrades (e.g. compressor wheel upgraded units). However, there are three problems with them: Fakes / non authentic replicas: When we first started testing these injectors back in the 2011-2012 time frame, the first set we received worked fantastic. Then, our supplier sent us a new set which were “much cheaper”. Despite looking the same, these did not work well, at all. The engine had misfire problems at idle. Upon investigation, we determined that this second “cheaper” set of fuel injectors was in fact a replica and was built using very poor manufacturing tolerances. Price: Why are there replicas / knock offs? The answer is simple: the authentic units are expensive! As of this writing, authentic “green giants” cost anywhere from $200-$250, retail, for a set of 4. Availability: For reasons not yet determined, the availability of the “green giants” has diminished as of late. Most retailers have them back ordered. Bosch 52# Fuel Injectors As of more recently, the Bosch 52# fuel injector has become an option for the 1.4T. They share most of the same benefits that the “green giant” does, however, there are two problems with these fuel injectors: Not “EV1” connector: This one's simple. They won't directly plug in to the engine harness of the 1.4T. As such, to use these, you need to add bulky, costly harness adapters. Price: Looking around at various retailers, a set of these injectors, with the required harness adapters will run you anywhere from $250 - $300 for a set of four. Siemens-Deka 60# (SD-60) Fuel Injectors You can throw a stone and hit five gear heads that know what these injectors are. They were one of the first widely-available “EV1” style aftermarket fuel injector upgrades for the LS1 engine dating back to the end of the last century. These fuel injectors are high performance with enough fuel flow to solve the fueling problems of almost any streetable high performance build. They are readily available, being very easy to source. They are also one of the lowest cost high performance aftermarket fuel injector available, with a set of four pricing in at $150-$200. Because they are available in the “EV1” style connector, they can be used on the 1.4T without harness adapters. If they could be used on the 1.4T, they'd be the perfect choice. However, they are also notoriously finicky in some regards, and based on our early research, were ruled out as feasible. That's changed now, though. First, a discussion about the problems with them. Curse of the SD-60s One of the issues that's plagued tuners since the SD-60s became available is their short pulse width operation. The larger (higher flowing) a fuel injector is, the more fuel it moves for a given amount of “open” time (pulse width). Also, the larger a fuel injector is, the more difficult it is to control at extremely short pulse widths, because the internal parts are larger, and therefore, heavier. If a fuel injector is operated at too short a pulse width, the injector can “misfire”. The ECU tries to open and close the injector so fast, it cannot do so reliably. When it fails to open and close, no fuel is injected, and the cylinder misfires. These two issues confluence to make idle operation with SD-60s extremely problematic and challenging. On larger engines, like the LS1, for instance, which displaces .7125L / cylinder, the SD-60s are relatively close to providing the correct amount of fuel for idle operation. However, on smaller engines, like the 2.0L SC MPFI (LSJ) – which displaces .5L / cylinder – the SD-60s cannot run at a short enough pulse width for proper fueling. So a tuner is left with making a choice between two not-so-good scenarios. Either they can live with the injector misfiring at idle, or they live with pinning down the minimum injector pulse width to avoid misfiring, but which causes the idle mixture to be too rich. The 1.4T is EVEN SMALLER, clocking in at .35L / cylinder. In other words its fuel demand per cylinder is roughly HALF of the LS1 engine. This means the problems seen on the 2.0L are even worse. We figured this out back in 2011-2012 and quickly eliminated the SD-60s as a viable choice for the 1.4T at the time. However, we recently revisited it, and now we think it's the best choice. Here's why... The LUJ/LUV Chassis Control Module Did you know that your Gen 1 Cruze / Gamma II has a variable speed fuel pump? It's true. And it's controlled by a discrete ECU called the Chassis Control Module (CCM). The CCM receives messages from the Engine Control Module (ECM) that dictate what the fuel pressure supplied to the injector rail should be. Why? The answer is that because these vehicles are both MPFI and turbocharged, the fuel pressure supplied to the injector rail needs to be varied based on how much boost there is in the intake manifold. The factory calibration varies the pressure between 300kPa (43.5 psi) and 400kPa (58psi) depending on the operating conditions. In our earlier research, we experimented with SD-60s and a lowered commanded fuel pressure in the ECM calibration. However, at the time, the CCM would not honor requests from the ECM to run the pump at a pressure level that was low enough to work with the SD-60s. Less is More More recently, however, we decided to look into whether we could change the CCM's calibration to honor requests from the ECM to run the fuel pressure at a level that was low enough to support the SD-60s. Here's the deal: Yes, the SD-60s flow way too much fuel (at idle) for the 1.4T – but that's at 43.5psi. If you lower the fuel pressure, the flow rate goes down. And as a result, the pulse width can be increased. With a specific CCM calibration, matched with an ECM calibration, we found we were able to run the SD-60s on the 1.4T with NO problems. No injector misfire. No rich idle. In fact, our engineers thought the 1.4T idled SMOOTHER with the SD-60s than even the stock injectors, or the “green giants”! SD-60s are Looking Like the Best Option The ECM/CCM is simply a reflash (software update) for the vehicle. If you're switching injectors, you're going to be flashing the ECM anyway. We always thought if the SD-60s could be made to work, they'd be the best fuel injector for the 1.4T. They're the cheapest and easily available. With TRIFECTA's ECM/CCM calibration, now the SD-60s are a real option for 1.4T tuners!
  22. An HSN** means that the part was installed and tested for correct functionality on a TRIFECTA development vehicle, with the TRIFECTA calibration product, and if any specific calibration changes are necessary to support or optimize it, these changes have been established and finalized. As such, customers wishing to install this part on their vehicle may do so under the Advantage line product and will not require any customization beyond, in some cases, a parts-specific calibration update. The following is the manufacturer's description of the product: “The K&N 63-3097 AirCharger air intake system replaces the restrictive factory air filter and air intake housing on specific Chevrolet Malibu models. K&N air intakes are designed to dramatically reduce air intake restriction as well as smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the original air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s turbo inlet for a guaranteed power gain. The tube accommodates the factory mass air sensor and crank case vent hose. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install, usually in 90 minutes or less using your vehicle’s existing factory mounting points. This air intake system can be installed easily with common tools.” (For full info, please see the manufacturer's website here: https://www.knfilters.com/mobile/mProduct.aspx?prod=63-3097) In general, our hardware team found the unit to be easy to install, and easily reversible for dealership visits. It increases “intake noise”, so turbocharger “whine” and “bypass” events are more easily heard. The serviceable filter element reduces long term air filter element replacement costs.

  24. More boost for your turbo Equinox While the all-new Chevrolet Equinox 2.0T performs well out of the box, the TRIFECTA recalibration result is nothing short of amazing. The new 9 speed automatic transmission is geared to take full advantage of the power curve of the LTG engine, and with an extra 50 horsepower at the wheels on tap, with TRIFECTA, the Equinox turns into a tire shredding machine. FUN FACT: The engineering team that developed the all-new Equinox product had just wrapped up the Cadillac ATS-V tuning program. Despite just working with a 600HP Cadillac, by the time they were done with the Equinox, they were giggling everytime they took off from a stop with a heavy pedal! 2.0L Turbo LTG dyno (on 91 octane pump gas) (this vehicle is a 2018 Chevrolet Equinox with the 2.0L Turbo LTG engine) - stock wheels/tires Instilling sport in the Equinox's DNA Raw power is great, but how that power is delivered is almost more important. When you're dealing with a transmission that has so many gears, purposeful, intelligent, and confident shifting is critical, as is pedal response. TRIFECTA's driveability engineers worked tirelessly to instill a sporty driving character without making the vehicle feel busy-shifting, laggy, or twitchy. Milder manners, when needed We also understand there may be times when a milder persona is desired. As is found on most of GM's most expensive vehicles, with TRIFECTA, you can switch back to a more docile pedal response and transmission shifting, on the fly, with TRIFECTA's exclusive Driver Selectable Vehicle Modes ("DSVM") feature, using the cruise control button. A show of hands, how many in this room want to be able to disable "auto stop"? "Auto stop", "start stop", or whatever you want to call it, you know what we're talking about. It's when the engine shuts off entirely (and sometimes disconcertingly) when the vehicle comes to a stop. Its meant to help with fuel economy, but in many cases its more of an annoyance, than anything. Some vehicles have a discrete button to disuade the vehicle from auto stopping, but the all-new Equinox is not one of them. With TRIFECTA's exclusive Performance Auto Stop Mode ("PASM"), now you, too, can say to your Equinox, "No sir, I don't want auto stop right now." No, we won't give you a button to tape to the console for this. PASM, like DSVM, is also controlled by the cruise control button. Calibration customization, for those who need it Need support for a wicked dual-snorkel cold air intake kit? With TRIFECTA's Elite calibration tier, customized calibration support is available** for modifications which are not compatible with the factory calibration. ** Support for modifications is subject to specific terms and conditions TRIFECTA MY2018+ Chevrolet Equinox Performance Calibration Key Features: - Specific power gains of up to +48 ft-lbs of torque, +49 horsepower measured at the wheels - Dramatically improved drivability characteristics for everyday driving maneuvers - Exclusive Driver Selectable Vehicle Modes ("DSVM") for switching performance profiles on-the-fly - Exclusive Performance Auto Stop Mode ("PASM") for disabling Auto Stop when in Sport mode - Installs in about 20 minutes - Flash back to stock functionality included For more info, see here: https://www.trifectaperformance.com/store/product/2401-2018-chevrolet-equinox-20l-turbo-advantage/
