Correct! I rewrote the entire air Fuel portion of the code to correctly handle the MAF. My fuel tables are no longer trim maps they are target Lambda maps done just like modern day EFI systems do. Also the code handles the super fast response times of the MAF. The MAF has 10ms or better response times while the AFM is at above 100ms, the door in the AFM is heavy and takes time to react to a sudden air flow change. You can't just make a MAF pretend to be a AFM they are not the same devices.

Two very knowledgeable tuners taught me the basics for tuning and how the formulas work I then combined this with what I learned about the Motronic and I then re-wrote the parts of the code that needed to be changed. Here's the setup in the car, next post
