Technical Information
About the remap
Stage 1 optimization for the BMW X3 xDrive30i 252hp increases power from 252 to 288 hp (+36 hp, +14%). 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 MG1CS003 ECU (engine code B46B20B / B48B20B) via the OBD2 diagnostic port – no ECU removal required. We use Autotuner Autotuner, ByteShooter Toolbox, CMD CMDFlash and other professional tools. Results are verified with a dynamometer measurement.
In addition to Stage 1, we offer the following services for the BMW X3 xDrive30i 252hp: XHP gearbox tuning. All work is performed using professional equipment (ZF 8HP50 gearbox).
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.
