I am needing to get my fueling upon engine startup just perfect. For this reason, I started VE tuning using speed density mode.

On startup, I am in cells that are way rich: 20, 17, 22
How do you change these VE Cells???

I see that cells 0-15 are mapped out in the Main VE table, but does anyone know where cells 16-22 are and if they can be changed?

Thanks a TON!

Is this even possible? Does anyone know where these ve cells come from?

16 is idle with a/c on
17 is idle
18 is idle with a/c in gear
19 is idle in gear

20 is cold (open loop) idle
21 is decel
22 is open loop for everything but idle

If for some reason you need to lean out the open loop stuff you need to look at the open loop a/f multiplier tables. For the idle tables just worry about the ve for the map and rpm you see at idle.

Ahhh So open loop cells (the ones I am having trouble with: 20 and 22) can be changed in the table that says "Open Loop A/F multiplier" ...gees I feel dumb

Thanks P Mack!!!
