    You log too many useless parameters for a WOT run. All three AFR, IAT, Vehicle Speed.

    Datalogging is important to determining the health of the tune and your car. As well as point to potential issues that could cause the tune to not work effectively. Cars do vary sometimes so it’s recommended to do some logs for review.
    Here is a list of items to set up in your data log list. Datalog a 3rd gear pull 2500-6500 rpm, 100% throttle.

    A/F Correction 1(%)
    A/F Learning 1 (%)
    A/F Sensor 1 Ratio (AFR)
    Boost (Psi)
    Calculated Load
    Dynamic Advance Multiplier (DAM)
    Feedback Knock (degrees)
    Fine Knock Learning (degrees)
    Ignition Timing
    Intake Temperature
    Inj. Duty Cycle (%)
    MAF(g/s)
    RPM
    Throttle Pos.(%)
    Vehicle Speed (mph)

    This is sent by Eric from torqued Performance. These are the parameters that he requests. I dont know why he wants certain parameters that other people dont care to look at thats just him.M just lookinf for some simple feed back from you guys before i send off to him.

    Logging rate on the AP is bad enough without wasted bandwidth...

    Without knowing certain things, we're limited in what we can give you as far as insight. There's no knock, boost isn't oscillating, your injectors are maxed, you're logging too many parameters for a WOT pull, and you were doing well above the speed limit.

    The injector part you mentioned. I wonder if that could be a concern being only stage 2?

    It's a concern regardless of what setup you are running. The factory O2 sensor is pegged out at 11.14:1 AFR so who knows what the real AFR is.
