Installed Tom's Tune - Pull P1246 Trouble Code
The car was running fine for about a week. Every cold start and short distance driving, the car rpm's will drop to around 500 and through a battery light. P1246 is the alternator. My question is are the 2 related and can I removed Tom's tune to factory, take it to the dealer, then once done put the tune back in the car?

i don't think it's tune related man. yes you can remove tom's tune. go to diagnostics, trouble shooting, then restore original backup. once you do that though, it erases toms tune. you'll have to have tom email you the tune and load it back onto the predator before loading into the ecu

btw, i don't think it is, but to know for sure if the code is related to the tune, just go ahead and restore the factory tune to the ecu and see if you still have the problem

**EDIT: sorry, it's options, then troubleshooting, then restore original backup

Thanks. I did read your other post. I wasn't sure what fourm to post in.

For the record here's what I posted in the other fourm:

I have the Powertrain Warrenty, however the alternator is not covered. I might just leave the tune in. Thats what I was thinking, it would be hard pressed to say if the 2 were related. I've had a flicking problem since day 1. I had the YFR0 installed and made no difference.

The dealer said it would be no charge to have the system tested.
