What is M-Tuner?

Available through MSL Performance for all M838T/M840T McLarens and 992 Porsches, M-Tuner is your complete OBD flashing suite. It empowers you to flash M-Engineering's world-class tunes, capture high-speed datalogs, and manage vehicle features like dyno mode and fault codes, all from your own garage or the racetrack!

Stage 1 tunes for 91, 93, & 100 octane
A stock performance file
Anti-Theft Maps

For those pushing the limits, our custom remote tuning service is available as an option. Simply send your datalogs to our experts at MSL Performance, and we'll provide revised maps tailored to your car's exact setup, from stock to 1000+ WHP monsters.

ECU Requirements

For Porsche 992 owners, no ECU removal is needed! The entire process is done through the OBD port.

For McLaren owners, the ECU must be sent to us at MSL Performance for a one-time bench unlock. We handle this with an express 2-day turnaround. Ship it to us overnight, we'll unlock it and ship it back the very next day, ready to go.
