is it possible to take the stage 1 out of one car and into a nother

 

Sure, whatever can be done can be undone. The real issue will be whether it's financially sound or not. You will have the labor to put it back to where it was and the cost to have the computer reflashed to OEM default. Now you have to pay to have it wired to the second HHR and the real question will be how much does it cost the dealer to download the reflash for the stage one and how much is the dealer going to charge you in addition. I think you would be close to break even with a new stage one purchase and leave the other car alone. Plus you need to consider warranty concerns.
The only way this should be considered in my opinion if the upgrade was no longer available through GM.

 

ya true i am just trying to see if i could save a buck or two

 

You would not be able to do the programming. Once the authorization number is given to GM and they load it to a VIN, it can't be used again. So no it can't be moved to another vehicle.

 

Removing it yes, reprogramming the new car might be a pain. I've done one on a cobalt and the tune is a one time dump from GM. We call up GM, give them the number supplied with the kit and they dump it into the dealer service computer we then dump that into the car. The way I understand it is it's a one time use.

I guess it might be possible to call GM and ask though.

 

I plan on removing the Stage Kit as well. I got way to much pinging after the stage kit install with the AZ fuel and Heat out here. I want to illiminate all possible future failures and just build up a RWD vehicle.

 

I called and they stated they will not load that program into any other vehicle, no matter what the circumstances are, so there is no way to transfer from one HHR to another.

 

well here goes another 800 dollars

 

The Stage tune can be copied with HP Tuners and applied to another vehicle, AFAIK. You won't get the dealer to do this, and you'll have none of the warranty protections available to those who did it through the proper channels. Moreover, there will be no official record of your vehicle having had the modification, so a dealer ECM reflash for another reason could leave you with a bigger problem than you drove in with. In spite of people's whining about the cost of TMAP sensors, I find the few hundred dollar investment to be very cost effective considering the performance gain and factory blessing. This, of course, is predicated on a reasonable charge for installation labor, which has already been discussed ad nauseum.

 

can you swap ecm's? get a stock one and move the upgraded ecm to the new ss?
