Technical Information
About the remap
Stage 1 chip tuning for the BMW 7 serie 730D 193hp increases power from 193 to 222 hp (+29 hp, +15%) and torque from 410 to 480 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 DDE4.0 ECU (engine code M57D29) via the OBD2 diagnostic port – no ECU removal required. Results are verified with a dynamometer measurement.
Under normal driving conditions, chip tuning a turbocharged diesel can reduce fuel consumption – in Eco mode, savings reach up to 1.1 l/100 km thanks to more efficient turbo operation and optimized injection.
In addition to Stage 1, we offer the following services for the BMW 7 serie 730D 193hp: EGR valve diagnostics. All work is performed using professional equipment.
If desired, the BMW 7 serie 730D 193hp 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.
