I'm trying to get my car tuned, and something just isn't meshing here. I have a copy of HPTuners and I've been working on some things. My current mods are as follows;
1995 Impala SS
2005 6.0L LQ4
EPS 222/226 .597/.598 112LSA+4
L92 Heads
LS3 Intake Manifold
NW 90mm Throttle Body
Mid-Length Headers
36# GTP Injectors
Yank 3000 stallMAF
I've been using my AEM wideband, and the values im getting for input into the table seems to be remaining the same. I've done the "rinse, wash, repeat" a few times, and it doesn't seem to be changing alot.

Also on a cold start, I'm seeing 16.9-17 on the wideband, then it swings all the way to 13.2-13.0 after about a minute. IDK wtf is going on and it's puzzling the hell outta me. I'm ordering a new wideband sensor today, and going through to check it again once i get it.

Your entire OL fuel table is set to 1.0 (even wayyyy under the temp that you should be tuning at). That's why it's so lean during startup. Set it back to stock for all columns at 158degF and below.

Thanks Steve. I'll change that and see where that puts me. Would that also explain my other issue? Always getting negative numbers when logging MAF, no matter what changes are made?
