I'm confused...looking at a recent XFI log my actual A/F was 11.3-11.4 in some frames...target is set at 11.3 but it's still pulling fuel...O2 correction is at -7 to -9%...shouldn't the O2 correction be close to zero or maybe be adding a little fuel?...I'm just not getting a handle on XFI...doesn't seem to respond the way I think it should...do I need to tweak the VE table some more?...how fast does XFI respond to fuel changes?...as an example if the actual A/F is 11.0 and target is 11.3...should you see a correction in a few frames...1 frame...10 frames?
