Mercedes-Benz AMG-GT ECU remapping
71 files available
About remapping
The Mercedes-AMG GT accounts for 71 files in our catalogue, with the 4.0 V8 biturbo as the core engine, alongside the 3.0T of the 43 AMG versions. It is the brand's dedicated sports car, engineered by AMG from the ground up.
The split is striking: 35 Stage 1 files against 33 Stage 2 — practically even, reflecting how many of these cars arrive with hardware already fitted. The ECUs are MED17.7.5, MED17.7 and MG1CP002.

How much does the 4.0 V8 biturbo take?
It has genuine headroom thanks to twin turbocharging, even from very high factory figures. We still apply conservative margins on an engine like this.
Why is Stage 2 almost as common as Stage 1?
Because a large share of these cars arrive with exhaust or intake modifications already fitted. If your car is standard, Stage 1 applies.
Is the work reversible?
Yes. We always keep the original ECU file, which matters particularly on a vehicle of this value.
