Hi
Picking up my 2021 4 m40i next week as my new project car.
My plan is to go full Akrapovic from turbo back, Mst intake and turbo elbow along with ecu and gearbox remap.
However there seems to be a lot of confusion and contradiction around 2021 models forward having locked ecus therefore unmappable.
Can anyone clear this up, especially in the UK.
And I'm not bothered about voiding warranties etc.
