Thanks for the responses guys. I set it to 31 and the AFRest is now a lot closer to what the wideband is showing. My problem now is that the car is stuck in open loop. Causes of that? Could I have fouled out my front O2? I can get it to cycle during cruise at some points, but during idle the car shows 0 on all trims and O2 will not cycle. I have adjusted the BISS, played with the MAFcomp settings, and double checked my fuel pressure(with vac line off).
