How to get PCM back to stock?
 

So I've moved to California, which means I need to ditch my Rotofab and switch my Maggie over to their CARB compliant EO tune.

In order to do this, evidently I need to set the PCM back to stock, purchase a programmer from Magnuson, use this to upload the now stock file from the PCM and e-mail to to Magnuson for modification, and then they send it back to me and the programmer load it into the camaro.

How do you go about the first step of this? Do I need to go to the dealer, or is there some kind of "reset to stock" trick built into the car?

What software was used to tune your car and who did it?

I would keep the RF and then keep the current tune. Then flash the CARB complaint CA tune into the car and put the OEM airbox on the car. Pass CA emission, then swap back over to modded once you are clear of the CA emission process.

Sorry for the long delay... moving sucks... It was done by Leading Edge Performance in Las Vegas using HPTuners. I called him and he doesn't seem to think setting it back to stock before loading the Magnusson tune would matter, but that is what Magnusson's own calibration department is telling me I need to do.

Can the car even be driven with the stock tune and a supercharger?

If not I guess I need to find a chevy dealer that is okay with me hanging around for a bit while I email tunes back and forth with magnusson.

No, I highly doubt the car can be driven on the OEM tune while having a supercharger on it. The GM dealer also cant do anything, you will need to find a performance shop that uses HP Tuners to tune vehicles to get this sorted out. That wont be cheap either, I would figure on at least $500 to go that route.
