Technical Information
About the remap
Stage 1 chip tuning for the MERCEDES BENZ C 250 CGI 204hp increases power from 204 to 253 hp (+49 hp, +24%) and torque from 310 to 357 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 ME9.7 ECU (engine code M271) via the OBD2 diagnostic port – no ECU removal required. We use Autotuner Autotuner, ByteShooter Toolbox, MagicMotorsport Flex. Results are verified with a dynamometer measurement.
Stage 2 is also available for the MERCEDES BENZ C 250 CGI 204hp – 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.
