I spent about a week going back and forth to work and think that my VE table is about as good as I can get it. But now I need help with the EGO Control Settings.

I can't find anywhere where it has a recommended starting point for the
"WB Controller Settings" see pic.

I followed the recommended settings for tuning but now I'm trying to setup up for running and I can only find instructions for the upper part of this dialogue.

I'm using TunerStudio and MS2 Extra

Thanks

Tuning a PID loop is non trivial, you can read about it here.

I would start with the defaults, and if you're getting pretty good tracking between your target AFR and the actual AFR, leave it be.

The defaults made my system oscillate big time. I followed the PID tuning instructions and it is now minimized and is pretty stable but there is still no real instructions on this part. I know the theory but it would be nice to have a starting point and not so much guess work.
