About the remap

Stage 1 optimization for the BMW X5 3.0i 231hp increases power from 231 to 249 hp (+18 hp, +8%). 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 Siemens MS43 ECU (engine code 306S3) via the OBD2 diagnostic port – no ECU removal required. We use Alientech KESSv2, CMD CMDFlash, Dimsport New Genius. Results are verified with a dynamometer measurement.

In addition to Stage 1, we offer the following services for the BMW X5 3.0i 231hp: XHP gearbox tuning. All work is performed using professional equipment.

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.
