BMW 320d (G20) Remapping
Independent Stage 1 ECU remapping for the BMW 320d (G20) (2019–2023), fitted with the B47 2.0-litre four-cylinder diesel. Subject to a suitability check. Workshop or mobile, same price either way, from £135.
The BMW 320d (G20) is an executive diesel platform commonly covering higher motorway mileage, where smoother torque delivery is often the main appeal.
Newer executive car owners covering long motorway commutes who want the latest B47 revision's torque delivery smoothed further.
Remapping the BMW 320d (G20)
A Stage 1 remap recalibrates the factory ECU software to improve throttle response and smooth out power delivery, within limits appropriate for a standard, unmodified BMW 320d (G20).
As a turbo diesel, this platform is also commonly approached for economy-focused tuning, which can improve drivability and reduce gear changes on longer journeys. We don't publish generic bhp or torque figures, since actual results depend on the specific vehicle's condition, mileage, and history, confirmed properly during a suitability check.
