About the remap

Stage 1 optimization for the BMW X3 2.5i 214hp increases power from 214 to 233 hp (+19 hp, +9%). 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 MS45 ECU (engine code 256S5) via the OBD2 diagnostic port – no ECU removal required. We use Alientech KESSv2. Results are verified with a dynamometer measurement.

In addition to Stage 1, we offer the following services for the BMW X3 2.5i 214hp: 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.
