    2020 Jeep SRT getting Codes after Cam install with ANN disabled

    Hey guys, I'm having a couple issues tuning a 2020 Jeep SRT after a cam installation. I'm getting an occasional starting issue when warm which seems to trigger some codes (screenshot of codes below). The codes always seem to pop up after cranking. I tuned it in Speed Density and disabled the Neural Network. I'm wondering if I may have missed a step when I disabled the Neural Network? The file referenced "Base" is the stock tune file and the 2nd "SRT File" is the unlocked map
    Also during a dyno pull the power seems to dip in the midrange and I can't seem to get rid of it. Tune File, Log, and pictures down below. Anybody have any insight with what may be going on?

    Thanks in advance

    Post your stock, unmodified version please.

    And, if you're actually the one doing the tuning you need to take it out of your remote tuning network. It cannot be viewed.

    Oops forgot to unlock the tune file. I added the Base File and the Unlocked tune file, it's the 2nd file in the attachments

    Thanks

    do a fuel reset, I dont know why, but HPTuners isnt able to do this in the scanner...lol.

    then dial in your injectors with ann.

    after this you can set your ve table.

    i miss throttle % in scanner.

    i cant believe your fueling is correct, because the pe table is flat.

    Thanks for the reply;
    This vehicle is running stock injectors, so you are saying I will need to dial in the ann first to where it's running decent then move on to VE?
    This is naturally aspirated so I kept the PE table flat to target 12.6 AFR flat throughout at WOT and dialed in the VE to follow that target.

    The ANN is a big piece of xxxx.

    Always tune injectors first to get the right fueling, otherwise you correct the wrong inj data with VE.

    I'm not understanding... The injectors are stock and it has stock injector data. Your saying I have to change the injector data?

    Try this out this should help with the Dip and might take care of that code as well.

    No matter what…it starts with dialing in injectors…..always.

    Airflow doesn’t fit with performance cams…never, even idle speed….

    If the basics fit you can easily do the rest.
