After waiting two or so weeks for it to quit raining and try out the ECU after an upgrade I have a problem. My O2 will not correct to the negative side. It corrects to the positive side just fine.
Example: Set idle VE at 50. O2 corrects at around +10%.
Set idle VE at 65. O2 goes to zero, blips rapidly back and fourth between zero and -10. Stays mostly at zero and my AF is way rich.
It does this across the entire RPM range. I now have my correction limits at the max, checked all other settings and it looks normal. Even changing things like MAP decay, closed loop step and anything else that effects correction limits or correction speed has no effect on this. Any ideas? Tuning this way will be a PITA!
