Technical Information
About the remap
Stage 1 optimization for the BMW 7 serie 745i 333hp increases power from 333 to 355 hp (+22 hp, +7%). 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 ME9.2 ECU (engine code N62B44A) via the OBD2 diagnostic port – no ECU removal required. We use Alientech K-TAG, Alientech KESSv2, ByteShooter Toolbox and other professional tools. Results are verified with a dynamometer measurement.
In addition to Stage 1, we offer the following services for the BMW 7 serie 745i 333hp: 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.
