I just did a custom fuel system, 96lb injectors, 100mm MAF, and running E85. Anyway my tuner happens to be gone and I can't get it started on the new tune. My MAF table is completely different from stock one. I don't know enough to get it done. It starts and dies. It is rich as I can smell fuel and will get it to backfire through exhaust if I try to start it enough. I can't keep it running no matter what I do. I unplugged the MAF and I also tried going into the DIAG section and failing the MAF at 0HZ. What else can I do?

 

Post up the tune for us to look at.

 

Need to re scale the maf tables i bet... Try running the old one till your tuner can get it changed around...

 

Reduce fueling below 1200 rpms.
