7747 $42 1989 Chevy 4X4 need help tuning...FINALLY!

[Psycho_Daleic]

you need to down load the lates files from this sight for the 7747 ecm to get an accurate data log.

Thanks Ony.
I'm using EagleMarks $42-1227747-V5.2.adx, $42-1227747-V5.9.3.xdf with the original AMUD bin. The latest highway data log(with AMUD) is attached above.
I haven't switched bins to the ASDU (Factory 24pin) yet but I am hopeful it will be a better starting point than the AMUD it's currently running. There is a huge difference (see attached) in the VE1 table between the two. Hope this doesn't destroy the new engine. Your thoughts?
Also, should I disconnect the battery every time I switch ECM/chip, or is key off enough?
