Mercedes-Benz is one of the world's most popular ECU tuning platforms. The OM651, OM654 diesel and M260/M177 petrol families are all well-established tuning targets, with extensive real-world data confirming consistent results across the complete model range.
The Mercedes C-Class and E-Class with OM654 2.0D diesel respond to Stage 1 with +40–60 Nm. The M260 2.0T petrol across A200, A250, CLA250 and C300 delivers +35–55 Nm. AMG models with M177 4.0T twin-turbo V8 respond to Stage 1 with +50–80 Nm, pushing A45, C63 and E63 well beyond factory output.
Mercedes ECU tuning covers the complete lineup via OBD port for most modern engines. Older ME/CDI systems may require bench access. All calibrations preserve MBUX, AMG modes and 4MATIC systems. Fully reversible.
