I have just tried to read it, I want the stock file so I can save it if we ever have to go back to it. How do I do a calibration only flash?
It wasn't tuned. He bought it stock with 25,xxx miles on it, doesn't seem like anyone has ever played with it???

Do I have to read the stock file first to see which OS it is running or are all 06 Trailblazers the same? I will try to flash the tune file right in but I don't want to lose the stock file.

Hmmm , I have not played around with the reading part anymore , I really don't know which of the 5 BCM fuses to pull , I suppose I could pull all 5 and see what happened but not something I really want to do .
There is a stock file on Holdencrazy.com and I have one plus the TIF updated one . Yeah , the PCM should have the same OS in the 06 year 4.2L , unless it is the EXT and has the 5.3L , then it is probably different .
I see your point in wanting to be able to read the current tune off the PCM thought , I have not heard anything more from anyone .
I did pull 2 of the 5 fuses when I tried reading last time but it still failed , so don't know who said to pull the BCM fuse .

Yeah we tried the BCM fuses, there are a few of them we tried all of them and then 1 at a time, still get the same error messages.
