*2025+ models of the new 992.2 variant include the newer "locked" H80 MG1 ECU's. These new ECU's have a longer work flow to unlock and flash hence the longer downtime and added costs*

With the M-Engineering ECU flash for the Porsche 992.2 GT3 and GT3 Touring, adjustments are made to improve the throttle response, remove top speed limiters, adjust air/fuel ratios, and modify ignition timing and much more to improve the overall driving performance of the 4.0L flat-six engine. M-Engineering still utilizes all OEM ECU engine safety strategies.

We have base ECU Calibrations supporting the following vehicles:

  • 992.2 GT3
  • 992.2 GT3 Touring

Live Map Switching

On-The-Fly Live Map Switching comes standard on all calibrations (Stage 1 and Stage 2). The purpose of this feature is to quickly change between different power levels relating to the octane you are filling up with. This is all controlled via the cruise control stalk. Information on how to use Live Map Switching can be found here.

Engine Safety Map Slot (Slot 5)

M-Engineering has written custom code for additional engine safeties beyond what is provided from the factory. Our engine tuning strategy has always been for engine safety first, and power second. This has allowed us to maintain vehicle reliability and have the most powerful calibrations on the market proven time and time again in competitive racing series, at the drag strip, and setting world records at Pikes Peak.

Our custom code has allowed us to implement what is called “Detonation Defense” which is an engine safety that detects excessive knock events. When knock events beyond a set threshold are met, within 20 milliseconds, the car will automatically be put into map slot 5 for a brief period of 10 seconds. In map slot 5, the car will have reduced power and engine load to prevent damage. This proactive approach protects your engine and allows power to return once conditions are again safe.





PLEASE NOTE - FOR THIS PRODUCT WE WILL NEED YOUR ECU SHIPPED TO US. EXPECTED TURNAROUND TIME IS NEXT DAY AFTER RECIEVING.
