    E38 406 Stalling

    I am still battling stalling coming to a stop, or changing gears. For the most part coming to a stop it doesnt stall but definitely isnt happy. Just now I had it stall hard when putting into reverse while rolling. Is there something Im completely missing why the return to idle is so unstable? Only thing that really stands out is the spark relation. Im going to lower the minimum airflow a little and see what happens tomorrow.

    Thanks

    My experience is limited and never have i tuned anything with an automatic, but I would probably have a play with [ECM 12135] Idle Trans Drive Airflow to see if that helps.

    Add to your BRAF. Reducing it will only make the stall condition worse.
