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
