Remapping the BMW X3 xDrive20d
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 X3 xDrive20d.
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.
