I'm having an issue with AFR at idle also. Target AFR is all the way up to 14.5 at idle but it is usually reading around 12.9-13.0 at idle. I did have the timing at 24 degrees at idle. When I pulled it back to 18 degrees in this new table the AFR at idle started reading closer to 14.0. Still not at the target but it seemed to help.
