well im not sure if its common, but i was programming it and just as it was about to finish said Error something something. so i just ordered a madz28 pcm. and i plan on using tunercat again to modify shift points. so hopefully, it doesn't happen.

Sometimes they'll come back. just leave the battery disconnected for about 1/2 hour and it may come back to life.
I've done a whole bunch of em, and about every 10 or so, will have a problem either reading or writing to it. When they have an error during the read, they will almost always come back. If they error during the write, its about 50/50.

Ive never killed a pcm while tuning. Ive done well over 500+ uploads and not one killd pcm. Even had a low battery in a car and the tune still went through. Go ahead and get it.

yea, i tried unplugging the battery for about 30 minutes, and not life is restored. just waiting for my madz28 tuned pcm to come in and send the dead one back it. this will count as a core right? it has no physical damage or anything, just pcm needs to be reset somehow.
