ECU tuning & bubbling installation BMW 4 Series F36 420i B48 100 hp increase!

Thanks for your help, ECU tuning and bubbling installation on a BMW F36 420i B48 engine.

The ECU is located on top of the engine compartment and can be easily detached when the B48 is the same F. To write from OBD, you need a bench unlock, but AutoTuner allows you to do that. bm3 and other OBD flashers will also allow you to write.

However, this MG1 type ECU takes an hour to write from OBD. However, AutoTuner can also write on this bench, and that too in two minutes.

ECU tuning was also installed this time. Horsepower is increased by more than 100 hp to 300 hp (published values).
