Hi guys,
Long time listener, first time caller.
This site rocks, Flashscan rocks, and my car... rocks at WOT, but not so much at idle
2003 Z06, TTiX twin turbo, forged motor with mildly lower compression, 72cc ported LS1 heads (don't ask), and a baby turbo cam. I wish I had the specs, but I was given the cam # and Cammotion's phone #, not a grind spec (since I guess the grind was supposed to be a secret). For the purposes of this post, let's assume it has more exhaust duration to help the turbos and maybe a little more lift than a Z06 cam, but not much.
I did 2 passes with AutoVE today on the road. Most cells wanted anywhere between 4% and 8% added, a few cells under high vacuum wanted 10%ish, but for the most part it looked like my heads/cam were mild enough that the PCM could have LTFTd its way through the changes without issue.
Now, first question - I am using an LC1 - how much variance between passes is normal? For example, on pass 1 EFILive told me to scale a cell by 1.09. The next pass it told me to scall it by .97. I am kind of inclined to just leave well enough alone if I can get all the cells to want to go slightly negative (.95 to .99). Is this acceptable practice or do you guys always get yours nailed right down to .99 or 1.00?
