Mercedes-Benz Clase G ECU remapping
242 files available

About remapping
The Mercedes-Benz G-Class accounts for 242 files in our catalogue, with a genuinely split personality: the 3.0 CDI diesel for serious off-road use and the 5.5 AMG V8 biturbo and 4.0T for outright performance. Few vehicles cover such extremes in one model line.
Stage 1 makes up 188 files, with 33 Stage 2, 18 speed limiter removals and 15 pop and bang. The ECUs include EDC16CP31, EDC17CP10, EDC17CP57 and MD1CP001 on the diesels, plus MED17.7.3 and MED17.7.5 on the AMG petrol units.

Do you work on the AMG versions?
Yes, the 5.5 AMG V8 biturbo and the 4.0T are present in our catalogue and account for much of the Stage 2 work.
Does it affect off-road capability?
A well-judged map preserves throttle progressiveness, which is key in technical driving. On a G-Class that matters as much as outright figures.
Is the work reversible?
Yes. We always keep the original ECU file, which matters particularly on a vehicle of this value.
