Hello ECU-Tuner,
I'm new here and I as many other would like to learn about ECU-Tuning, but only for my car.
I have a BMW E39 525D, and if that one dies I'll buy an 530D.
As I am a DIY-Guy, I would like to do everything myself, because then I kno everything what has been done. :D
Greetings from Germany,
Bobo
