About the remap

Stage 1 chip tuning for the BMW 1 serie M140i 340hp increases power from 340 to 402 hp (+62 hp, +18%) 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 MG1CS003 ECU (engine code B58B30M0) via the OBD2 diagnostic port – no ECU removal required. We use Alientech KESSv2, Autotuner Autotuner, 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 1 serie M140i 340hp: 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.
