    O2's dipping to 35mv and timing killed?

    Have a look a the log. 6 litre V8 Gen4.

    O2's have been having an issue for sometime, been messing with Intake Charge Temp Bias tables mostly...... but I just noticed when they have this issue the timing dies as the same time......

    Jump to frame 6417 for an example.... timing dies, o2's flatline and it shoots lean.

    TTT- Anything ever happen with this? I have an issue where when I come to a stop at idle my O2's go to Zero, and my LTFT and STFT's also stop reporting, the car idles rough, timing dies and then they all of a sudden come back and everything is fine.

    Try a Write Entire, or flash the car back to stock, then copy over your changes into the new stock file. After so many writes with the new beta, PCM's are going whacko.
