Product Description

 

 

The M-Engineering M-Tuner Suite with Live Map Switching is a sophisticated ECU calibration and performance software package developed specifically for the Porsche 991.2 Carrera (including Carrera Base, T, S, 4/4S, GTS, and 4GTS) platform. This advanced tuning solution unlocks improved throttle response, optimized boost control, refined air/fuel ratios, and enhanced ignition timing — all tailored for each fuel type and driving scenario. Featuring on-the-fly live map switching, you can quickly swap between fuel/octane calibrations while the engine is running without needing to reflash each time. Wireless OBD flashing through the included M-Tuner v3 dongle means you can perform tune updates from your garage without removing the ECU, and easily revert to stock when needed. This suite brings track-worthy performance and everyday drivability together in one complete package.
