Tuner and PCM

[ryaleon]

So decided to take the diablo tuner off of my C6 as I never drive it and use it on the H2. Restored original tune back to C6 to unlock tuner. Everything is fine.

Take it over to Hummer. Select vehicle type so on and so forth. Then go to tunes. It backs up the original fine. But while flashing the new tune gets an error. Says cant read pcm. Shuts off.

When I turned it back on it says flash unsuccessful restoring original. Ok I guess. Restores fine. Take tuner off. Go to start H2...silence.

PCM fried? Thoughts?

Also how do I remove the PCM for replacement?
