BMW has always done so on the 1.6i engines – limiting the engine’s performance through software. It started by limiting the first generation Minis throttle angle, even when the driver was pushing the throttle pedal all the way. And it affects this generation too.
The naturally aspirated Mini One always gained around 30hp from a remap. This version however is the exception to the rule. Because it is equipped with a valvetronic system on the cylinder head, it is possible to have fantastic gains over the stock power without replacing a single bolt on the engine itself.
Why? Because BMW has limited the engine’s power output by limiting valve lift at high rpm. So even if you are going full throttle, the valves will not open fully any more. This is done very smoothly so the driver will never know it could make more power.
On the dyno however, things are slightly different!
How to get more power
By removing torque limitations, adjusting valve lift and improving the AFR and ignition timing of course! Through our Stage 1 ECU remap, we increase the valve lift and throttle opening to increase power. The gains are amazing. The engine sounds different too, as it delivers an amazing 45hp over stock.
