Lo and behold, I haven't found ONE single entry by searching the ECU P# in the search bar, that has a definition made up for the 2.8 30v.... the ECU box in question is [ 3B0 907 551 BP ] and clearly states Bosch ME7.1 beneath it. How does one go about making a definition? Or is there someone here who already has and I missed it? Any relevant help is appreciated. I cant justify the money spent to buy a tune via PES/APR/AWE/GIAC/whoever else when I can learn to do it myself. Especially after talking to local tuners who write custom files (and want considerably MORE monies) who have found certain section of code and places on fuel and timing maps where it's done rather lazily.

Man, i'll be brutally honest... I did read my own ECU with Nefmoto but I don't know where to go from there. Also, I've been told that blindly following the guides leads to bricking your ecu rather quickly. One guy called it jumping into a live fire exercise without knowing its a live fire exercise.

The people telling you things to discourage you from tuning your car are either clueless or want to make money off you and have no actual skill so they want to discourage you from possibly figuring out how little they do for the $.

Certain, dumb tuners will actually try and give you intentionally false tips and tricks to screw you up and help cement the idea they are the only ones who should be touching such magical technologies.

Def read the guides, the forum, the FR and since you are working on an obscure ecu, dig through others and start to learn what maps look like within 7.1 and compare to yours.  Hex is your friend.
