TRIFECTA presents: GMC Terrain (1.5L Turbo) MY2018--Present 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) 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.
TRIFECTA's 2018--2019 Terrain recalibration is complimented by a fully developed 9-speed automatic transmission calibration to support the increased power delivery profile and to offer dramatically improved driving characteristics from everyday driving maneuvers. The complete powertrain calibration also includes ESC (Stabilitrak) program enhancements.
 
Specifications of the TRIFECTA Performance 2018--2019 Terrain ECM software reprogramming:
-Fuel economy is improved (up to 39.5MPG 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 flash loader
-Tested on all available grades of fuel (87, 89, 91, 92, and 93 octane).
 
Specifications of the TRIFECTA Performance 2018--2019 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 2018--2019 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
 
Additional information and availability:
- This powertrain calibration includes a TRIFECTA powertrain calibration file specific to your vehicle and includes a flash loader device
- Powertrain calibrations currently exist for North American vehicles only, with more regions to follow
 
The TRIFECTA Elite Powertrain Calibration with Individualization (Custom Profiling) for the MY2018--2019 GMC Terrain includes calibration individualization, remote diagnostics, and comprehensive aftermarket hardware software integration support. Includes a TRIFECTA flash loader..
