Ok went for a log today after changing my VVE slightly from a earlier log. This is the tune after the change and the log I got with it,
Callie VVE setup 01.tun VVE log after 1st change.zip
I then filtered andadjusted my VVE again. I went for another short drive and this is the result,
Callie VVE setup 02.ctd VVE log after 2nd change.efi
I don't know what I did wrong but the last log was going very lean
I checked the WOT and it appeared ok. This is doing my head in to say the least

It doesn't look too bad, Just remember to log for long trips to make sure everything averages out nicely.
It's probably just the VVE co-efficients going a bit off. What you can do it not the values in thos cells, and you know they need to go up a bit. So make your normal changes and after regening, see which way they moved. If they lower, or not sufficiently higher, manually kick them up and regen.

No worries I will look at that next time I change my VVE. How do I get rid of the negative corner on the map??? I tried a few things but it just doesn't look right
I just manually change the values to make them more sensible. Just continue the curves of the VVE and flatten it out up over 6800 RPM, unless of course you have the limiter set higher.... In that case you need to use real data.

Hey Simon just a quick one - does raising the VVE figures richen up the AFR????
Did you see my photo's of the plugs I pulled today. I might just make my whole table rich and work my way leaner. I don't want to fry my engine :(
Cheers

Yes. Higher numbers in the VVE indicate that more air is flowing into the motor. This tells the ECM that more fuel is needed to keep the commanded AFR. so the ECM uses these figure to estimate the required fuel quantity for "stable" engine conditions. Varying load, RPM and throttle position will cause the dynamics to add/remove fuel and will alter the final AFR. This is why you need to run long "stable" periods to get the fueling correct.
