Technical Information
About the remap
Stage 1 optimization for the MERCEDES BENZ GLA 45 AMG S - 421hp increases power from 421 to 473 hp (+52 hp, +12%). Naturally aspirated petrol engines have limited scope for power gains, but optimizing ignition and fueling maps delivers a smoother power delivery, more responsive throttle, and a noticeably more pleasant driving experience.
The remap is performed on the Bosch MG1CP002 ECU (engine code M139) via the OBD2 diagnostic port – no ECU removal required. We use Autotuner Autotuner. 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.
