M-Engineering ECU Tuning for Porsche 992.2 GT3 / GT3 Touring with Live Map Switching
Unleash the Full Potential of Your Porsche GT3
The M-Engineering ECU Tuning Suite for the 2025+ Porsche 992.2 GT3 and GT3 Touring is the most advanced calibration available for Porsche’s naturally-aspirated 4.0 L flat-six engine.
Built from extensive R&D and motorsport testing, this tune refines throttle response, adjusts fueling and ignition, removes top-speed limiters, and optimizes drivability — while retaining full OEM safety logic and introducing new proprietary M-Engineering protection code.
Note: 2025+ models use newer locked H80 MG1 ECUs, requiring additional unlock time and cost (≈ 2 weeks turnaround).

Engine Safety & Detonation Defense
Safety comes first at M-Engineering.
When knock events exceed safe thresholds, the ECU automatically switches to Slot 5 within 20 milliseconds.
This temporary mode reduces power and engine load for 10 seconds, then restores full output once conditions normalize.
This technology is exclusive to M-Engineering and proven through competitive racing, drag passes, and world-record runs at Pikes Peak.
