About the remap

Stage 1 chip tuning for the BMW 3 serie 340i xDrive 326hp increases power from 326 to 383 hp (+57 hp, +17%) and torque from 450 to 520 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 MEVD17.2 ECU (engine code B58B30A) via the OBD2 diagnostic port – no ECU removal required. We use Autotuner Autotuner, CMD CMDFlash, MagicMotorsport Flex and other professional tools. Results are verified with a dynamometer measurement.
