I have read the whole 31 pages of this thread but haven't seen anyone with F30/N55/N20 (Gasoline) cars have tried this. I would like to try this on my F30/N55 (335i). What type code would you use it to try this? Is there any resource that shows the Alpina cars type codes?

Thanks in advance!

If you had read all posts you will get the answer, someone with N20/N55 tried and got lim mode. It is because the Alpina EGS firmware for 8HP70, which some diesel car also uses it, but N20/N55 with 8HP45.
For your car, paid solution is available. (i.e. xhp tool)
