Greetings, thanks to this forum I have been able to learn many things about ecu me7.5 and 7.1, currently I have just purchased a car which has me very enthusiastic which with the help of what I can read here I hope to make a good corduroy to have fun a little like I have done with my 1.8t mk4.

but I come with other doubts far removed from all that, I decided to help a friend with his AGU 1.8t m3.8.3 and the truth is that I have not been able to understand how this ecu manages the turbo boost and before ruling out the upgrade to me7 .1 or 7.5 I would like to know if it is possible to add 2 steps to the ecu m3.8.3

Thank you very much in advance


I'm sorry if I don't express myself correctly, it's just that English is not my native language.
