Hello, I pulled the chip from my 1994 E36 M3. I'm currently working on a XDF for it so I can extend the MAF fault table and remove the sensor. Can anyone give me some input on what these identified maps might be? Image

The table at 7750 that is full of the value 128, I'd suspect it could be a low load lambda table. I have a similarly populated table in my wholly unrelated but still Bosch xdf. Values higher than 128 would be richer and below 128 leaner. If you have a wideband and / or an emulator it would be fairly easy to test.
