Is it necessary to omit data less than stoich from the VE afr error histogram?

My PE is set at 35 tps, and anything other than PE is really lean. Like 17.5:1-off the wideband.

I tried to multiply the whole table by 1.15 and it threw a code at idle.

Should I continue to log with this lean condition? Or should I try to multiply by 1.05?

I imagine some more knowledgeable guys would answer if you posted a tune and log but the short answer is no, you're way too lean to be running for any amount of time. Is your KR off the charts while logging?
There has to be either a mechanical or tune issue

I got it figured out with some outside help. I just kept adding to the table where it ran lean. Still working on it. Its crazy how much the VE table needs to be modified from a few modifications.

Yeah it is surprising how much it changes. I have a recent post asking about my VE numbers going into the negative due to a cam change, I'm down 20% in some cells in the lower flow areas.
are you doing the Copy-Paste-Special-Multiply by % for your for your log histo to the VE table?
