Assessment
The BMW X3 1.8D 136hp is a 2.0L turbocharged diesel engine producing 136 BHP and 320 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 220 BHP and 440 Nm — a gain of around 84 BHP (62%) and 120 Nm (38%).
This engine scores highly for remap suitability, with gains weighted towards peak power — the improvement is most noticeable at higher RPM. The tuning headroom is classified as high, based on the percentage gain available from the factory output.
From a technical perspective, the ECU is typically a Bosch EDC17 (likely), and the transmission is many variants use zf 8-speed automatic (where fitted); manuals also exist..
Considerations: High tuned torque: check transmission torque capacity and service history.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.
Fuel economy note: economy gains unlikely at full power; depends on driving style.
All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
