Just a thought... On my 07 charger, if you put the car in neutral while rolling and then turn the key to the "start" position, (as if your trying to start the already running engine) hold for a few seconds until you here a chime. This will totally disable the traction control until you turn the car off and restart it.
I wonder if this would work on the Crossfire?? I haven't had the chance to try it yet.
No, you will not grind the starter motor. The computer recognizes that the car is running and won't let the starter engage. WARNING, I have only done this on my Charger. If your starter grinds, don't blame me!
