Truck drives fine,logs fine guessing its another on board computer kicking it off. wow not post must be the first one
Remove fuses for OnStar, Radio, BCM.
I am up to 15 fuses still will not flash
make it 20 now,says its rearming then will fail the flash,sounds like vats maybe kicking on?

the flash log
With every fuse I can pull and still have it connect and alt. keys ,unchecked high speed it went though ,I try putting some fuses back that I didn't know what they where and it failed after 5 min flash dam didn't think the bench flash would save me but looks like it took it,so how can I pin point what system is causing the problem besides 10 more hrs and hopefully not a cooked ecm of trying stuff
well looks like the jokes on me 7.5 doesn't work on this truck after 12 hrs, lost mark another one for the lost column
I have done 03 SS trucks before why would that get changed not like I am using beta,had the ecm out 6 times 25 fuses for a software problem ,hptuners reads it V8 works,wait Its me right lol
It looks like something is interrupting the bus...
