Technical Information
About the remap
Stage 1 chip tuning for the BMW 5 serie 540d 320hp increases power from 320 to 403 hp (+83 hp, +26%) and torque from 680 to 800 Nm. Turbocharged diesel engines offer the greatest chip tuning potential – optimizing boost pressure and injection maps delivers significant gains in both power and torque from low RPM.
The remap is performed on the Bosch MDG1_MD1CP002 ECU (engine code B57D30) via the OBD2 diagnostic port – no ECU removal required. We use Alientech K-TAG, Alientech KESSv2, Autotuner Autotuner and other professional tools. Results are verified with a dynamometer measurement.
In addition to Stage 1, we offer the following services for the BMW 5 serie 540d 320hp: XHP gearbox tuning. All work is performed using professional equipment (ZF 8HP gearbox).
If desired, the BMW 5 serie 540d 320hp can be upgraded to Stage 2 – a deeper optimization delivering even greater power and torque gains. Stage 2 involves advanced ECU calibration taking into account exhaust system and intercooler modifications. Contact us for a free consultation to evaluate Stage 2 potential for your specific vehicle.
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.
