M-Engineering M-Flash ECU Tune w/Live Map Switching Porsche 992.2 Turbo S (2026+)

Unlock the performance potential of your Porsche 992.2 Turbo S T-Hybrid with the M-Engineering M-Flash ECU Tune. Developed specifically for Porsche's advanced 3.6L twin-turbocharged hybrid powertrain, this ECU calibration optimizes boost control, ignition timing, fueling, and throttle response to deliver increased horsepower, stronger torque, and improved acceleration while retaining critical factory engine protection strategies.

Unlike conventional ECU tunes, M-Engineering has developed proprietary calibration software specifically for the 992.2 Turbo S and its electrically assisted turbochargers. The system incorporates advanced turbo shaft-speed management, custom PID control, and boost-by-gear strategies designed to improve performance without exceeding the intended operating limits of the electric turbochargers.

Development included more than 800 dyno pulls, extensive road testing, and validation under demanding driving conditions. The result is a comprehensive tuning solution engineered to balance increased performance with smooth power delivery, drivability, and drivetrain protection.

M-Flash includes on-the-fly Live Map Switching, allowing drivers to select between different fuel-octane calibrations using the factory cruise-control stalk. Five map slots are provided, including dedicated 91, 93, and 100-octane calibrations, an ACN91 map, and an automatic engine safety map.

For additional protection, M-Engineering incorporates its proprietary Detonation Defense system. When excessive engine knock is detected, the ECU automatically activates a reduced-power safety calibration within approximately 20 milliseconds. This protective mode remains active for approximately 10 seconds before normal power delivery can resume when conditions permit.

The calibration also includes enhanced Porsche Sport Exhaust valve control, a 200 RPM increase in the rev limiter, automatic start/stop elimination, and additional driving enhancements. Stage 2 calibrations include loud cold-start elimination for vehicles equipped with upgraded exhaust systems.

Available in Stage 1 for vehicles with factory exhaust hardware and Stage 2 for vehicles with upgraded exhaust systems, M-Flash is an excellent performance solution for both stock and modified 992.2 Turbo S models.

Each purchase includes an M-Tuner V3 wireless dongle for diagnostic fault clearing and data logging. Due to the security architecture of the 992.2 ECU, the engine control unit must be removed and shipped to M-Engineering for professional unlocking and calibration.
