    Specifications of the TRIFECTA Performance Chevrolet Corvette C7 MY2015+ and Corvette C7 Z51 MY2015+ 6.2L LT1 ECM software reprogramming:


    -Gains of +31 ft-lbs @3550 RPM and +24 WHP @5575 RPM, under the curve; (and +26 ft-lbs and +22 WHP peak vs peak on 91 octane)

    -Powertrain calibration has been tested and validated for various environments, such as cold/heat, elevation, and variations in fuel quality

    -Power feels linear and immediately responsive (improved drivability and throttle response/attentiveness)

    -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

    -Extended testing of 100,000 miles with 100 hrs of wide open throttle testing

    -The TRIFECTA flash loader and Transparency featureset does not increment the ECM write counter or increment entries in the flash history

    -Optional: BCM CEL/Code disable

    -Return to stock functionality included with flash loader



    Specifications of the TRIFECTA Performance MY2015 Chevrolet Corvette C7 / Corvette C7 Z51 8L90 8-Speed automatic transmission TCM calibration software reprogramming:


    -Supplementary 8L90 transmission TCM reprogramming compliments the ECM reprogramming and completes the TRIFECTA Powertrain Calibration: designed to work in unison with the ECM reprogramming for optimized performance

    -Improved shift times in adverse shift patterns

    -Improved shift logic (improved drivability)

    -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 fuel economy with improvements made to torque converter slip profiles



    Specifications of the TRIFECTA Performance MY2015 Chevrolet Corvette C7 / Corvette C7 Z51 Chassis Control Module software reprogramming:


    -Optional supplementary CCM (Chassis Control Module) reprogramming compliments provides support for customizing CCM related vehicle systems

    -For TRIFECTA affiliates and TRIFECTA development partners: Full control over the AFM exhaust valves (cylinder deactivation exhaust flow control valve system) with engine RPM, engine load, vehicle speed, and Driver Mode Control setting based Vehicle Exhaust Valve (AFM exhaust valves) duty cycle and position specific actuation triggers

    -For TRIFECTA retail customers (OPTIONAL): Removing the OE Exhaust Valves (AFM/NPP) will no longer effect a CEL / MIL or related error codes (P26C8 and P12F0)

    -For TRIFECTA affiliates and TRIFECTA development partners: NPP (exhaust tailpipe flow control valve system) system controls with triggers based on engine RPM, engine load, and vehicle speed; use the NPP valves to eliminate exhaust drone

    -CCM (Chassis Control Module) diagnostics access: GM exhaust valve actuator relearn procedure and diagnostics support

    -CCM (Chassis Control Module) MIL enable/disable: P12E3, P12E7, P12E8, P12E9, P12EA, P12EB, P12EC, P12ED, P12EF, P12F0, P12F1, P12F2, P12F4, P12F5, P12F6, P12F7, P12F8, P12F9, P12FA, P12FC, P12FD, P12FE, and P12FF related MIL (malfunction indicator) can be disabled by the end user

    -Completes the AFM support both both engine cylinder deactivation profile improvements and corresponding and complimenting exhaust valve controls



    Installation Notes:


    -Estimated installation time of ~20 minutes

    -Premium fuel is recommended, but not required
