Are there any differences in the software required to read a 07' PCM vs. 09' PCM. I have no problem reading and writing tunes on my 07' 6.2, just can't seem to read my buddies 09' 6.2L. I keep getting security related errors when tyring to read the newer motor's PCM.
I am running version 2.22.3152.18236
You'll likely need the newest beta to read out MOST 09 applications since 2.223152.18236 was released before virtually any 2009 applications were released.
Bill, Do you have a download link to a Beta release that would work? The only download link I can find is for the official 2.22 release...
contact support.
I just sent a requst in as well. Just purchased a 09 Tahoe 6.2L.
Go figure after driving home. I get a engine code. Unplugged the batt. It reset for one drive then came on again.
Looking to link to it just to see the code before the trip to the dealer.
