    Fuel Source - TQ Req. Lean

    Not sure how to interpret this. Does it mean that it went lean or, is it due to a referenced torque table and trying to lean out the fuel? I see that the lambda both commanded and actual are a bit off but what I would expect at WOT (.77) I think I'm missing something here.

    Log file attached.

    That was a crappy example as it had a ton of IPC Wheel torque errors that have been corrected. The issue still remains. I am doing more research. Thanks for looking.

    What did you do? I get this source too. And all I have done to the car is a CAI and my tune.

    It amounts to nothing as the commanded fuel and actual are right in-line with what I expect. It's not pulling timing or throttle so, I'm not going to chase stuff that in the end doesn't have any effect.
