Default wanna confirm ve stuff

Ok, I finally decided to load 2.0 on my PC at work well everything is making more and more sense. Here goes:
1. say @ 1600 rpm @ 25kpa my ve value is 55 and my LTFT is +8 and my STFT is -2....should my final learned be 6?

2. Do I change one ve value at a time or am i supposed to do multiple at a time??

by half to avoid overshoot, you can do multiples

i never did that half crap, its alright but if you get enough data int he log then you dont have to do that. shoot to get the whole ve at about -3 or -4 so when you go wide open you wont go rich from + fuel trims. you can make a spread sheet to do this all for you. otherwise you just take that 6% and multiply the cell by it, so multiply by 1.06

Yeah you need to adjust 55 by 6% not 55+6 or even 55+6/2 but 55+6% which is 58.3 total as per Master WS6.

i do 'muliply by %' on first few iterations (when you're way off) and then as i get closer (<7% off) then i use 'multiply by half %' and it works peachy.
don't do it cell by cell, unless you got a serious reason to do so. do the whole thing at the same time, or at least large areas, and make sure to set your 'minimum cell count' to 20.
good luck!

if the ve table is close, i would do each cell by hand. in 2.0 you can increase the precision to 1 decimal place and be mroe accurate. then i would make it 1% richer on top of that. when i was done i went back over the whole table where i was not in PE (under 75 kpa is where i set it to not go in PE) and richened it up about 2-3% depending on how the numbers were. across the board im about 3-4% rich but when i go WOT i dont get the + trims locking in anymore and the car feels hella strong

yeah i left that one out. that will help things out a ton. i usually set mine to 10 or 25 depending how long the log it. plus look at trends in the ve and histogram to filter out bad numbers by hand

i wish we could do _real_ filters, like EFI has, so we could say things like
cellcount>20 AND TPS%change <10% AND openloop=false ...you get the drift.
then we could gather only the clean data, not just any data. another year, another rewrite, another little improvment...maybe

If you're trying to set the minimum number of cell counts, you don't have to choose a sensor, just enter the number you want in the "Cell Hits Required" box.
