I`m not an expert either, but that tune is not good for tracking IMO. Maybe a maf re scale will fix it or the lesser octane/fuel tune.
Some one will come along that can help.

wrong idea of LTFT
if LTFY is positive it means it runs lean and the exu corrects
in this case the trims learning is a bit erratic, but anyway we do not have the afr target in the log, we dont really know yet
yes need a maf scaling and definitely a timing reduction
PM for help if you want
