I think i have everything setup right. But..the filter button does not seem to turn on the filtering, and when i copy/paste..paste w/labels&multiply it gets lean.So far i'm just trying to get easy driving straightened out. Any suggestions? Thanks

on the filter, after defining the filter, are you applying the filter (ctrl+alt+f)?
for the leanness, can you post your tune and log?

And a log.

Actually you are running rich not lean. Lean is > 14.6, rich is < 14.6. Also your VE table has alot of weird spikes it should be smoother. Did you start with a base VE and add 15% across it? How many iterations of corrections have you made already?
I don't want to comment too much and send you the wrong direction as I've not messed with a custom OS yet.
Corrected - So no one would believe my previosly BAD info!

Actually, RICH is AFR's < 14.63:1 and LEAN is AFR's > 14.63:1 ;)

Couple of observations...
1) DFCO is still active! That will be where you are seeing the extreme LEAN condition. DFCO shuts off the injectors ;)
2) VE Table is way too erratic :eek:
3) When Speed Density you need to log the GM.DYNCYLAIR_DMA PID to see cyl density for the spark advance tables.
PM me an email address, I'll mod this tune a little and email back to ya.

Doh!, corrected my previous post. Brain fart.
