I have a 325i from 1993 and i wan't to try to tune up a little this old Motronic 3.3.1 ^^
In fact i want to improve the throttle response and make some little bubbles at deceleration ^^
I have found lot of XDF but can someone show me or send me the latest and more complete XDF ?
And also can some of you have already tuned maps ? It's for compare and understand
Thanks in advance and keep old ECU in time
