About the remap

Stage 1 chip tuning for the MERCEDES BENZ E 500 CGi 408hp increases power from 408 to 511 hp (+103 hp, +25%) and torque from 600 to 850 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 MED17.7.3 ECU (engine code M278 DE 48 AL red.) via the OBD2 diagnostic port – no ECU removal required. We use Alientech KESSv2, Autotuner Autotuner, ByteShooter Toolbox and other professional tools. Results are verified with a dynamometer measurement.

Stage 2 is also available for the MERCEDES BENZ E 500 CGi 408hp – the next level of optimization with even more significant power gains. Stage 2 involves ECU calibration tailored to modified intake and exhaust systems. Consult our specialists to evaluate the potential.

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.
