Thanks, I understand all that.
My question was a hypothetical,........ like what if the car doesn't start, you can't reflash it then. or..........
If the wife has it, and there's a problem, she'd be clueless, even if it is in the trunk
More or less, just wondering, if they could, if so... WOULD they flash it back ?

I carry my tuner just for that. If I have a problem and still have power I would load my stock tune back in. I started carring it because a few friends wanted to see it in person and then figured I would just leave it in the car.

I have taken my car into the dealer for service and they always reflash the car back to the stock tune. This doesn't effect your handheld tuner and you can just reflash your car with whatever tune you want.

I could have easily put the stock tune back in before taking the car to the dealer, but I would also have had to replace the aftermarket CAI with the stock airbox, which I could not do because of an injured back at the time.

Well, I have a definite yes, and a definite no and............. A lot of stuff in between.
Anybody else know this ??
THANKS

It looks to me like he said his understanding was no but I told you that I have already done this several times and I have a S/C and a whole bunch of other stuff. No matter how many times the dealer or anyone else flashes you car it doesn't effect the tunes on your tuner. Even if the dealer flashes your computer back to stock it is the same stock program that is already burned into your tuner. When the dealer flashes your car back to stock he uses your vin number to find the correct stock tune for your car, so if they flash it back to stock it would be the same as if you used your tuner to flash the car back to stock. Just load the tune you want just like you did when you first bought your tuner.

Your handheld has your stock tune and your present modified tune. No sweat just reset the fuc8er like you want. End of story.

When you put a tune in from your tuner it doesn't leave your tuner and go into the car. It's not like you have to suck it back out of the car so you have it. Like putting something on CD from your computer. It's still in your computer.
Make sence?

+1 w1ldcat. Once the tune is in the tuner it is there to stay. I often reload my custom dynotune after an adjustment and write it right over the dynotune loaded in the car. I can easily change a couple of parameters in my tune and flash the car. so the changes take effect.
