Overview

M-Engineering's ECU calibration for the naturally aspirated 4.0-liter 992.1 911 GT3 RS is loaded with M-FLASH as a bench procedure: the ECU is removed, sent to M-Engineering HQ and returned with the new software, typically about 24 hours after it arrives. The calibration improves throttle response, removes the top speed limiter and revises air/fuel ratios and ignition timing.

M-Engineering quotes approximately +30whp and +25wtq at Stage 1 and approximately +44whp and +29wtq at Stage 2, measured at the wheels on pump gas; results depend on the quality of the fuel and the modifications on the car. M-Engineering's example dyno chart shows a 992 GT3 RS with a Stage 2 setup on 93 pump gas, run on a Mainline ProHub dyno at its South Florida headquarters.

On-The-Fly Live Map Switching comes standard on both Stage 1 and Stage 2. Map slots are laid out by fuel: slot 1 for ACN91 (the 91 octane sold in Arizona, California and Nevada), slot 2 for 91 octane or 95 RON, slot 3 for 93 octane or 98 RON, plus a 100 octane map, so you can match the map to the fuel in the tank.

Frequently asked questions

Is this a bench flash or an OBD flash?
Bench. M-FLASH on this car requires the ECU to be removed and sent to M-Engineering HQ. It is flashed there and shipped back, usually about 24 hours after it arrives; there is no at-home OBD flashing for this calibration.

How much power will I gain?
M-Engineering quotes approximately +30whp and +25wtq for Stage 1 and approximately +44whp and +29wtq for Stage 2 on 93 pump gas. These are wheel figures, not crank figures, and they vary with fuel quality and modifications. M-Engineering's example chart was recorded on a Mainline ProHub dyno.

Which fuels does it support?
Maps are laid out for ACN91, 91 octane (95 RON), 93 octane (98 RON) and 100 octane, and Live Map Switching lets you change between them on the fly.
