    cammed 6.2 idle in gear issues

    Cammed 6.2 in a jeep jku. Often when shifting from drive to reverse it stalls. Or if you rev it on decel and put it into gear it stalls. Have played with minimum idle airflow for 1st gear and reverse with no luck. adaptive spark up and down, no change. Can't figure out what I'm missing. Log and tune attached Thanks!

    First off you have WAY TOO MUCH idle timing in it. Should be 16-18 degrees even with a larger cam. Next thing is you need to dial in the VVE. You can't just run it in "MAF mode" and expect it to run right.

    Didn't look past that. Could be way more wrong.

    Copy that. Thanks, like I said new to this. Didn't even notice dynamic airflow was disabled. Again, working off of someone else's tune. Runs and drives great otherwise.

    Unfortunately the GEN4 PCMs are incredibly forgiving. They can make crappy tooners look qualified. I see a lot of really bad stuff run half decent.
