Hey guys, i have a M50b25 BDM read from my project beemer, ecu is Motronic 3.1. I don,t know if anyone is even a tiny bit interested in such ECU's in here, but i want to find map on it and maybe i would be able to push my rev limiter a little further than it is now. Winols do not recognize any maps automaticaly, and i haven't got enough experience to find it with my own two eyes :) thanks in advance!

I'm interested in this kind of files, too. Maybe i will do a tune on this ecu, i will check the file and let you know about maps if you're still looking for it.

Hi all!
Would you be so kind as to clarify the structure of MAF table for motronic 3.1 (403). Why it has three axis? How can I understand, this table defines the dependency of output voltage from mass air flow, but there is third correction parameter. What is it?
Many thanks for any information!
