Designed to Fit
- 2025 - Present Porsche 911 Carrera Base / T (992.2)
- 2025 - Present Porsche 911 Carrera S (992.2)
Product Description
M-Engineering has been at the forefront of Porsche ECU tuning, and has spent countless hours of research and development to provide reliable performance improvements for the 992.2 Carrera.
M-Flash for the 992.2 requires mailing in your ECU to M-Engineering's Pompano Beach, Florida facility for processing and unlocking the ECU. Expected turnaround time is 7 to 14 business days. This is due to the extensive security protocols within these ECUs which are labor intensive to get around. The ECU will be returned to you with the tune already installed and map switching active! Please note that the tune can be overwritten if the dealer flashes the ECU. We recommend not having any updates done at the dealer to avoid the potential of this. If this does happen, the process needs to happen again with the unlock and the cost to reflash is $2000.
ECU Removal instructions are located here.
Adjustments are made to improve the throttle response, remove top speed limiters, adjust air/fuel ratios, increase boost, and modify ignition timing and much more to improve the overall driving performance of the 3.0L twin-turbocharged engine. M-Engineering still utilizes all OEM ECU engine safety strategies as well as our own custom engine safeties written with our unique code. M-Tuner and dongle flashing support will be released at a later date.
What's Included?
- M-Flash Calibration with On-The-Fly Live Map Switching
- M-Tuner V1 Dongle for clearing faults and datalogging
Maps are available in Stage 1 or Stage 2 (upgraded link pipes) calibrations. Please specify your specific hardware upgrades when you mail in your ECU.
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 5)
M-Engineering has written custom code for additional engine safeties beyond what is provided from the factory. Their engine tuning strategy has always been for engine safety first, and power second. This has allowed them 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.
The custom code has allowed them 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.
M-Engineering also has unique custom features for your Porsche which we include at the time of purchase. These are designed from custom code and are not available from other tuning solutions. These come standard on our OTS maps and are not configurable for change at the moment.
