V1 cant read/flash CAN controllers, including the E38. Need to get a V2.

I went to V2 I am using V2, I think I seen a BCM fuse, if should I pull it ? I am wondering if anyone here has done a avalanch with the 6.0 engine.
Interesting, you should only need to pull fuses for onstar and audio if you have an aftermarket HU and/or onstar is interfering with the read. have you tried not pulling the fuses? BCM fuse, dont pull it, no reason to and it might mess something up.

I have pulled the onstar and the audio fuses no go. It does have blue tooth added.
That shouldnt make a difference, thats what I was saying. It should only be an issue if you have an aftermarket HU, and Im gathering you dont so you probably dont need to pull the fuses.
That said, since you did pull the fuses it should still read, so I dont know. What build do you have, 7.5.3 build 36 is the latest. Also, hook up the flashscan first to the car, then to the computer, then open the tune tool. I know it can be picky on my TrailBlazer. What firmware are you using on your V2?

Eric thanks for taking the time to reply,I really appreciate it.I have the 7.5.3 what I am now hearing is I need to make sure I have the V70 firmware,I believe I have the 60
That might be it, and no prob. I check here often and although Im still a noob when it comes to tuning anything other than my oddball 4.2L I6 P10, I try.

Hmmm....there was another thread here somewhere that someone was having the same/similar trouble.
I think they pulled the ABS fuse as it was waking up half way through the read/flash process and causing the read/flash to drop out.
I THINK it was the ABS fuse...sorry can't remember 100%.

YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
DUCT TAPE.
IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.
