BMW offers a diverse engine lineup — approximately 45% diesel and 52% petrol across 731 variants in our database. Both fuel types respond well to Stage 1 remapping, with turbocharged diesel engines typically delivering the largest gains in both power and torque.
Around 51% of BMW engines in our database feature forced induction, making them excellent candidates for remapping. Across the range, Stage 1 gains typically fall between 8 and 160 BHP (averaging 48 BHP) and 15 to 280 Nm of additional torque (averaging 81 Nm). These gains come from optimising boost pressure, fuelling, and ignition timing — all within the engine's mechanical tolerances.
BMW engines have an average suitability score of 6/10, indicating good potential for Stage 1 remapping. As always, results vary by engine — check individual suitability scores to find the best candidates in the range.
A Stage 1 ECU remap optimises your BMW's factory software to unlock its full potential — no hardware changes required. Here are the typical gains across the range.
