    Lean during transient event

    Looking for alittle help. I am going lean when I bump the throttle or before I enter PE, causing knock. My VVE vs LTFT looks pretty close. Any suggestions?

    Under Fuel-General- Desoot Mode - Turn it to disable and re-log

    I have turned off the desoot mode and even added some octane (roughly 97 oct) and still seeing it when I bump the throttle...also weirdly at 3000RPM. Here is my log with the higher octane. Any help is much appreciated.

    disable injector desoot mode
    disable fast torque exit switches and max the torque values

    also try setting your dynamic RPM back to factory
