VE still not right!!!???!!!?? WTF
VE still not right!!!???!!!?? WTF how come i cant get my ve table dailed in?? i have values up in the 120-130 range w/ just the mods in my sig, also i live in 4000ft of elevation so i dont think my numbers should be that high. ive done this tuneing process many times but still my afr error histo. shows i need to adjust the ve table.wtf after so much gas being used im getting kinda pissed, any help appreciated i have a log of a long drive and one of a 1/4 pass but i dont know how to attatch them

Sounds to me like maybe you've disabled PE and you have been trying to adjust your VE in ALL of the load cells including the high-load cells where PE would usually be added.
If so, then change your method of tuning. You're probably making your high-load VE values way too high.
set you pe to the values you want. dont do the all one value method while trying to tune. then dial you ve in. what wideband are you using? try the multiply by half after a couple of runs. it will get easy.

leave the enable TPS to stock and the enable MAP to stock?
1.21484 1.20996 1.20508 1.20020 1.19531 1.19043 1.18457 1.17969 1.17480 1.16992 1.16992 1.16992 1.15137 1.13281 1.13281 1.27148 1.27148 1.27148 1.27148 thats what its at
i have it so that i get 12.5 at the TQ and 13.0 at the HP, is this good?
i have set my OLFA to 1.00 for all my operating temps (170^)
how many logs should it take to get my ve dailed in.?
to do the maf i have to set the freq. back to stock, and then use the MAF-AFR error histo.??

Means choose your A/F ratio that you want. PE is a multiplier.
If your VE table is correct, then you're commanding stoich A/F ratio of 14.63.
If you set all PE values to 1.15, then your commanded A/F ratio should be 14.63 divided by 1.15 equals--- 12.72 A/F ratio. (when in PE mode)
Then, you LOG your actual A/F ratio (with a wideband) and compare it to the 12.72 COMMANDED A/F ratio, and adjust the VE table for the differences.
For the guy above, the fact that his PE multiplier is all over the place to make an "actual" A/F of 13.0 shows that the VE table is off.
This is what I've gathered from reading. I'm not 100% on the process (cause I've never done it).

That means don't change the VE table by the exact % difference between commanded and actual A/F.
Multiply by 1/2 the difference. You do this so you don't keep overshooting, and undershooting. You want to be close, you cannot be exact (because conditions constantly change).

Or, you could increase/decrease it by the direct % error. So long as you have collected a good number of samples throughout your histogram, you will find that the relationship b/w % difference in commanded airflow vs what is produced is quite direct. This will get you "closer." You should be right on top of your desired result within 2 good logs.
