We have a demon here that we did 2.65 upper, 10% lower, ID1300s, and Fore Triples with E85. At part throttle, about 105 KPA, i keep getting a P012B code with the lightning bolt. What i have noticed is that everytime it does it, is that the bypass valve pos 1 goes to 4 volts, while the MAP is around 105 KPA, so my best guess is that it is not expecting to see boost with the bypass valve at that voltage but it is seeing boost and so its not happy about that.
Everything else seems to be great though. WOT is great, no issues there. I have read the few threads that pertain to that code, and tried a few things, but nothing seems to help. Does anybody have any ideas on what to do to keep this from happening? Any Help would be appreciated! I have spent a couple days now making changes that i feel should help, but no luck yet. Tune is attached.
