Mine is V1, and using V7.5. I´m will reinstall and check again, What is sure is that I´m not confident when I do a reflash, I did change the two cables, So I´m affraid that the divice could be damaged, but those things are not supposed to fail rigt?
Can you post the text that appears during flashing...
Can´t remember all but here is what I recall
Auto detect pcm
PCM Detected
Seed 7$... something
Initializing 1 of 4
Initializing 2 of 4
Initializing 3 of 4
Initializing 4 of 4
Abort
Flash memory can not be errased
This happend after I did a reflash. and every time I try was the same.
After that I try to do full reflash and a recover pcm and always I get the response that PCM was in an unknow state.
As I saw info in the pcm like vin, os, I give a shot to download the file tune, and that did work, after that I have no more problems, So I do not what happen. Next time I will save the messages.
My car is 00 Camaro with 02 OS and my pcm is dead, I have to purchase another one. And this last one Is a 02 Transam
That error can happen when the battery voltage is too low or too high. Make sure you have a good quality battery and that is fully charged before you attempt to flash the PCM.
Reading will still usually work even if the battery voltage is too low/high. Flashing requires the battery voltage to be very close to 12V which is needed to erase the ECM's memory.

Update...
New PCM flashed and working. I didn´t have any problems since last time.
I bought a PCM 12200411 and works good, well to be honest I don´t see any difference.
Thanks for your help
