    09 Challenger 6.1 with SRTMAX cam idle issues

    2009 Challenger 6.1 with Inertia SRTMAX cam.

    Only other mods are bored TB entry way, stock butterfly area. Ran perfect before the cam.

    This is one of those 09's with the NN disabled from the factory.

    Having issues dying at idle. After cleaning up the VE table I tried adjusting the Throttle Body Model and it seemed to work but if the car idled for an extended period it would go into throttle limp mode. I then adjusted the Mass Airflow values in the Feedforward Control -> Small and Large Range tables to mirror the changes to the Throttle Body Model. This took care of the limp mode but the car still has issues dying coming down to idle when slowing down in drive. Any insight?

    Give more Driver Demand percent at the low area. Until you slow down to the mph where it transitions to adaptive idle it is going to use Driver Demand. If you pull out nice and slow you probably will find it is smoother transitioning away from adaptive idle and to Driver Demand too if you have them closer to what it wants
