Can you remap BMW diesel engines?

Yes, BMW diesels like the B47 and N57 respond exceptionally well to remapping. Expect significant torque gains and improved throttle response.

Do you remap BMW ZF gearboxes?

Yes, our ZF automatic gearbox remapping delivers faster shifts, improved sport mode response, and better torque handling for remapped engines.

What gains can I expect from BMW remapping?

Typical gains are 30-50bhp and 60-100Nm depending on the engine. Turbo diesel and turbocharged petrol models see the best results.

Our Services for BMW

BMW's B47 diesel delivers 30-50bhp gains with dramatically improved mid-range torque — transforming the 320d and 520d. The B48 petrol (330i, X3 30i) sees 40-60bhp through optimised boost and ignition timing. N55-powered models (M135i, M235i, M2) unlock 50-70bhp with sharper turbo response. Each engine code receives a bespoke calibration accounting for BMW's MEVD17 or MG1CS ECU architecture and specific injector hardware.

BMW's ZF 8HP automatic is industry-leading, but factory calibrations prioritise comfort over response. Our ZF remap reduces shift times by up to 30% in sport mode, raises the torque limiters to handle Stage 1 engine output safely, improves rev-matched downshifts for spirited driving, and enhances launch control on M-series vehicles. We calibrate for each specific ZF variant — 8HP45, 8HP50, 8HP75, and 8HP76.

BMW's B47 diesel engines in the 320d, 520d, and X3 20d are already efficient, but our economy calibrations unlock 10-15% further improvement by optimising injection timing, common rail pressure, and boost curves for motorway cruising. Particularly effective on the B47 where BMW's factory map leaves considerable efficiency headroom in the mid-range torque band.

BMW diesels — particularly the N47 and B47 in 1, 3, and 5 Series — are well known for DPF issues when used for short journeys. The EGR swirl flaps on older N47 engines are a notorious failure point. We diagnose whether the issue is soot accumulation, ash loading, pressure sensor drift, or swirl flap carbon buildup, and apply BMW-specific software solutions through the ISTA-compatible OBD interface.

BMW's SCR AdBlue system uses Bosch dosing modules prone to crystallisation, particularly on the 520d, 320d, and X3 20d. The NOx sensors upstream and downstream of the SCR catalyst are common failure points on higher-mileage F and G-series vehicles, triggering the dreaded mileage countdown warning. We identify the specific fault through BMW live data and apply the correct software correction.
