Constantly Moving Spiky VE Table

[ctuinstra]

I'm fairly new to this but have read and learned a lot. I have recently changed to a boost reference fuel pressure regulator and changed out the injectors to a split pattern (still 60lbs) and I'm trying to get a good tune. I've set up the tune file for VE scanning (disabling MAF, etc.) then run a scan and the errors are all over the place. Really high in one cell and very low in the next cell. So I multiply the data back in by half, I run it again and it still wants more, and run it again and now it's way too much. Back and forth I go chasing my tail. The VE table is has some terrible spikes in it now after starting with a fairly smooth table. I just can't seem to make it happy, especially low RPM/low MAP.

Using a AEM wideband via serial.

Sorry, I just realized I posted this in the V8 section. Trying to remove it....

you need to disable the MAF in order to tune VE correctly

I forgot to set the fail frequency on that set up. I had it set on previous ones. That's a good point. I will have to go back and make sure that's set.
