TRIFECTA presents: GMC Terrain (1.5L Turbo) MY2020--2024 Powertrain Calibration Reprogramming (flash tune)
TRIFECTA is pleased to announce the immediate availability of the 2018--2019 GMC Terrain vehicle software recalibration (reflash) for vehicles utilizing the 1.5L Turbo (RPO: LYX, LSD) with 9 speed automatic transmission (9T45 / RPO: M3U). Specific gains over factory calibration are up to (uncorrected) 35lb-ft of torque and 48 horsepower with no vehicle modifications beyond the updated software calibration.
 
Specifications of the TRIFECTA Performance 2020--2024 Terrain ECM software reprogramming:
Fuel economy is improved (up to 30MPG highway observed / 1.5L), dependent on fuel grade and driving conditions Retains all GM OE diagnostics and ECM functionality Retains all OE error code reporting and functionality Emissions readiness checks are present; emissions compliant Maintains functionality of ABS and TC systems Knock detection mechanisms and OE engine knock detection sensitivity is retained Return to stock functionality included with EZ Flash cable and software Tested on all available grades of fuel (87, 89, 91, 92, and 93 octane).  
Specifications of the TRIFECTA Performance 2020--2024 Terrain 9-speed TCM calibration software reprogramming:
T87A transmission control module (TCM) DOES NOT need to be removed from the vehicle. -Improved shift times in adverse shift patterns Improved shift logic - shifts are progressive and purposeful Does not shorten transmission life or increase cooling requirements Retains all OE diagnostics and TCM functionality Retains all OE error code reporting and functionality  
Improved driving character:
Vehicle responsiveness is improved: Vehicle responds more aptly to throttle input at low speeds, power delivery is more linear under performance situations Transmission shift strategies improved: Shift strategy is largely “factory” at light pedal positions to provide a familiar driving experience, but downshifts are much more progressive and purposeful at higher throttle conditions  
Supplementary Featureset of the TRIFECTA Performance 2020--2024 GMC Terrain powertrain calibration software reprogramming:
TRIFECTA's Performance Auto Stop 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) Improved knock detection and control strategies: Reduces incidents of knock when 87 octane fuel is used, or vehicle is operated in adverse environments  
Installation Notes:
Estimated installation time of ~20 minutes Premium fuel is recommended for maximum power output, but not required ECM (Engine Control Module) modification is REQUIRED NOTE:  Please DO NOT ship the ECM with the retaining bracket attached.  Any package contents besides the ECM will be discarded, including brackets, harnesses, etc.!  
Additional information and availability:
- This powertrain calibration includes a TRIFECTA powertrain calibration file specific to your vehicle and includes an EZ Flash Cable (TFEZ010U)
- Powertrain calibrations currently exist for North American vehicles only, with more regions to follow
 
TRIFECTA Advantage+:
The TRIFECTA Advantage+ Powertrain Recalibration includes calibration individualization, remote diagnostics, and limited aftermarket hardware software integration support.  If you have certain modifications which require tune customization, or have certain special requests, our Advantage+ tier offers unlimited updates for certain mods/requests for as long as you own the vehicle.
