My VE table looks silly... but the AFR is where its suppose to be so i leave it be.
i tried smoothing it and AFR went crazy so i undid that.

Like atomic said,, thats the best way to dial it in..
i always tune when im towing a heavy trailer works great and takes forever to run it thru the RPMs.Slow transistions are the key.

Well starting over really helped. The first round of VE tuning left the table nice and smooth! I am feeling kuch better now.

What did you do? go back to your last known good tune?

Basically i just smoothed my current table so it made sense. No more rockiness, then logged from there. My log from last night looked really good. It was pretty consistent. Also before i was applying the correction via paste multiply. I went back to the way i previously did it by doing groupings or individual cells.

I have also read somewhere that increasing the resolution of the VE table when scanning will yeild a more accurate reading. I think HPT rounds up or down when it moves up a column. Not sure on EFIlive.

Do you use the smoothing function? I will highlight a portion and click it a couple of times.

That's how I like to do it. Paste multiply almost always makes my fueling tables a jagged mess.

^^^Black and Beatdown, can you give a little more detail on this, I've always had the same problem with the ve table...thank you!!

The more professional way to do it is to look for general trends from the scanner, and make changes based on that. A blind "paste-multiply %" will make the table a mess. In general the table should be smooth, because the fueling requirements are fairly linear with respect to manifold pressure and rpm.

The paste multiply he's talking about is based off a ben factor or commanded vs actual and put in a scaled factor. In a perfect world, paste and multiply "should" be spot on but in most cases its not. I have even built ben factor pids for logging ltft and stft, but for some reason if I paste and multiply, it acts like its applying a different percentage. So I normally highlight an area that was about the same ben on the map and scale those cells in the ve, vve, or maf. It just seems to work better that way sometimes.
