I'm trying to lock in a tune using an E67 from an 08 trailblazer, and the STFT trims just stop after a couple minutes. Anyone know what is going on? All the stock components are used, but they are on another engine (L28) I am only using 1 O2 (B1S1).

To answer my own question: Random misfires are triggering a OL fault and when that happens it stops adjusting STFT and LTFT.
