Programmers and Warranty

[ccdies]

As far as your programmer is concerned, that is just an OnStar error. Nothing more.

Same thing will (may) happen with those insurance company monitors and they have no affect on warranty.

Thanks

My understanding is that regardless of what Black Bear, Diablo or any other tune company will tell you, the 2014+ trucks have a flash counter that cannot be reset. The # of flashes will alert the dealer/GM that there was probably a tune done. If there's a problem with the motor or drive train I can see how they might not cover under warranty.

 

Until I can get better info to the contrary about the flash counter, as much as I want a tune to clean up the crappy performance/drivability issues, I'm staying away from a tune.

 

Where is the info of the engine and/or trans being programmed stored? Where is this mystical "flash counter?" If one were to want to tune the transmission, would it possible to buy a spare TCM, tune it, swap it in, and never have a "flash count" stored anywhere. You could then swap the original and tuned TCM if you needed to make a warranty claim.
