Disconnecting battery for 20 minutes Is it true if you disconnect your battery for 20-30 minutes you will loose whatever tune/program you have running on your car and will return it back to factory settings?
Thanks

I am the tuner and I have cleared the codes. I'm starting to wonder if a sensor or some wiring was jerked around under the car by one of the straps. Our software (ie EFI Live or HPT) doesn't have access to the BCM though as far as I know...

If I reset my PCM/Disconnect my Battery/Battery goes dead will I lose my tune?
---Nope... your tune is stored in flash memory... only way to lose it is if you reflash your PCM. It may idle poorly at first while the car is "relearning" how to idle however. This should only last a few minutes.

Does your code show Current or History?

If you connected axle straps for the dyno around the rear axle, check the driver side for the ABS sensor plug pulled loose. On F bodys, the plugs harness hangs down and often the axle strap gets wrapped around that harness and pulls the plug loose.
