problem autotuning

[CurtD]

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

[TAQuickness]

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?

[CurtD]

Ok thanks.

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
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.
