No aftermarket box or tuner. Just the same trick you have been so far affraid to try. I know a Charger owner or two who have used this same trick so I was not affraid to try it on my Challenger.

Get your car moving about 10 mph or over and turn the key to start again. Immediately the radio will turn off. Continue to hold the key there for a few more seconds (not more than one or two seconds) and you will get a chime and the ESP/BAS error light on the dash will come on, then release the key.

The starter is disabled from re-engaging via a solenoid so no harm will come to your flywheel or starter. And if the solenoid fails...ah, who hasn't done it (or had a girlfriend/wife do it) by accident in an older car without such a solenoid and it didn't cause immediate and catostrophic damage.

You'll have to do this every time you start the car and you can not re-engage the ESP/BAS without turning the car off. This trick disables the center dash mounted switch in front of the shifter until the car is turned off and back on so don't use this trick if you expect to be driving on wet or slippery roads when you may want to engage the ESP/BAS.
