doing autoVE

[nathans1987]

just started doing auto ve wondering on your thoughts i think it looks pretty bad any hints? does it look like i'm doing it correct.

Doesn't look bad to me. Have seen ALOT worse.
I would try giving it a bit of a smooth and then go again.
Something like this.

cool thanks. when i get my ve table done how close to the commanded afr should my real afr be? because now its not very close. and no matter how many times i log the same squares in the AutoVE thing it almost alwasy is different each log. shouldnt i start to see it being 1.00~ or close to not from 1.00 too 1.15 or .93

I usually start with a fairly wide spread of data and then slowly pull the filters in tighter and tighter.
Start with only using data from cells with 20 counts or more...then move to 30, then 40, then 50 etc.
When logging/driving....if you need to back off the throttle....take your foot off completely so you can later filter out decel data.

cool will try to do that.

i was wondering if people could post up there logs for AUTOVE for a standard ls1 so i can see what i should be getting etc and the ve tables to go along with the logs.

Nathan, Im also only new here but i think if u keep logging and making small changes you should get it pretty damn close then if you want to get someone opinion again post anotehr tune file up

[nathans1987]

I think I may have mine set up wrong or a faulty unit because my sensor almost always reads lean. Ill do the auto ve then update the tune and I only usually update cells with over 50+ counts. Then it reads lean still. And the tunes I do feels slow compared to standard. I kind of expected it to feel faster. And at low rpm it dies before it goes. Ill do a couple more logs and post them up maybe someone can interpret them.

Try starting off with less than 50...maybe 10
I know some of the more experienced guys dont exclude any cells....but just look for patterns...which is what I tend to do nowadays.
If you see some cells in the log which look waaaay out compared with the others around them...don't alter them.
Look for patterns. Things like a group of cells with similar BEN's. Then there's a good chance they actually need adjusting.
Post your tune and go for a decent drive (30min's or so) and post the log.
Someone will help you with it.
