Thread: Step in VE table...

  1. #1

    Step in VE table...

    I have been tuning the VE table for a while now. Lots of smoothing and tweaking over time. Every time I log, the AFR% error tells me to remove feul at 2400rpm at all loads. So what I get is a step. I have tried smoothing and blending numberous times and still get this. Not sure what is going on here. I must have something set in another table that is comanding something else. Attached is the latest VE after logging. I did not do any smoothing or blending on the last two logs to show what my findings are more clearly.

    What mods? If it is wanting to pull fuel, why do you keep trying to smooth it?

    The built-in smoother sucks. Do hand smoothing by following trends only. I'd recommend you leave the 1200rpm and below to exactly what you get by tuning and dont smooth it. That's just my opinion.

    Cam only with typical BOs.

    It just seams odd. I thought it was supposed to be smooth all across, not jagged with peaks and valeys. It just does not make sence to need more fuel at 2000rpm than 2400rpm.

    More stuff I am learning. I have looked at other VEs in the repository and did not see anything. So I should just continue to listen to what the AFR tells me then?
