Have you tried the ECMTuning forums that's a great place since not everyone here uses Link.

Yeah actually I ha e ..not much help to me ..I have a question because I seem to be confused to this,the VE that's only for airflow or does it controls air and fuel.i am running lean past .4000rpm and trying to out if its appropriate to add fuel wit the slider.help from anyone would be appreciated.thanks

Looks like a fueling problem to me... I'd check out your fuel system and find out where/why you are dropping pressure.

You should def. watch the tutorial videos on ecmlink, and also search the forums there is an awesome write-up by a member can't remember the name but it's a good 20-25 pages long very in depth. To get you going in the right direction with your lean condition, yes adjust the VE table increase the values to get more fuel, decrease to get less. But there are many determining factors in getting it tuned correct start with the tutorial videos.

i would for sure start here its a lot of reading but you might want to begin reading upon this for a basic start, then you can run down your fuel issue.

Thanks a lot for all your replays guys..also my main reason for posting is also because I wrote em tuning about the VE table and this is the reaponce I got back so that's why I was confused as in to why it adjust (fuel) or (air) or both at the same time


ECM-tuning responce.

When you say "the fuel tab only stop at 127.5", I think you mean the maximum VE value allowed in the SD VE table is 127.5%. Although that is correct, it's irrelevant because the SD VE table should only be used if you need to adjust airflow values. I suspect your airflow values are OK and you need to focus on fuel.
