Hello,
I hope I didn't make a mistake by asking a question here. I am interested in where to start learning, because I would like to enter the world of ECU, to learn the basics, how and what it does. When you started, where did your resources come from, how would you start now if you were in my position. My goal is chipptuinig, and that is very difficult I know, so I would start with some DPF OFF, EGR OFF, and other things. :D
