    Default Option to lock the g80 rear end?

    I have the g80 locker in mine, is it possible to lock it through efi live? It would be cool to have that in the dvt thing. I'm still working my way through all this, so maybe it's there somewhere.

    OH PS I'd also like to be able to adjust how this thing operates. I want to change it so that if it's activated, it stays activated for like 3 seconds or so. That way if I spin on ice or snow or something, I don't get the bambambam.

    I know the G80 in my rear end is a mechanical locker so no way to change the settings via EFILive. I think some of the newer fullsize trucks have electronic locking ones though, but not sure how they're controlled.

    The G-80 is all Mechanical... IIRC you can put it in reverse and ease on the throttle to spin the tires ever so slightly. I was told you can make it lock up like that? Never tried it, i replaced mine with a Eaton LSD before it Gernaded..

    Thanks for the clarification man, wish I could replace my G80 with a Eaton. Dang oddball 8" rear end, not an 8.6" like the V8 models get.

    No kidding, the TB platform has 3 different rear end sizes. 5 pass I6 models have an 8" rear, 7 pass I6/5.3 and 5 pass 5.3 have the 8.6, then the SS has the 12 bolt 9.5" LSD.

    It's mechanical? Huh, the first time it did that bambambam to me I asked about it on dieselplace and was told it had an electronic locker. I never actually checked for any wiring back there and just believed what I was told.
