How remapping works on a petrol BMW 1 Series
With a petrol engine the remap works through the ECU's ignition, fuelling and turbo boost tables. Re-calibrating them within safe limits releases power that is already there, rather than adding anything to the engine.
How the BMW 120i 150 compares
Among the 9 petrol 1 Series engines we have figures for, the 120i 150 ranks 3rd for power gain, 5 bhp below the 1 Series petrol average of 25 bhp.
Across our whole catalogue the average petrol remap adds 27 bhp and 51 Nm, so this engine's 20 bhp and 35 Nm sits below that benchmark.
