About the remap

Stage 1 chip tuning for the MERCEDES BENZ CLS 450 (3.0T) 367hp increases power from 367 to 422 hp (+55 hp, +15%) and torque from 500 to 600 Nm. Turbocharged petrol engines respond exceptionally well to ECU optimization – adjusting ignition timing, boost pressure, and fueling maps unlocks the hidden potential built in by the manufacturer.

The remap is performed on the Bosch MG1CP002 ECU (engine code M256) via the OBD2 diagnostic port – no ECU removal required. We use Autotuner Autotuner, CMD CMDFlash, MagicMotorsport Flex and other professional tools. Results are verified with a dynamometer measurement.

Every vehicle undergoes full diagnostics before and after the remap. We keep a backup of the original ECU calibration and guarantee the option to revert to stock settings at any time. JVK PRO is a professional chip tuning service in Riga with 16 years of experience.
