1/2 hour straight of pulls to get your WOT fueling? Do you just randomly change things or something? If you at least do an educated guess based on your maps and logs, it should only take a few pulls to get very close.

This is my timing log from 3500rpm

you could do with rescaling your map to make better use of "big maps" too.
sometimes i find if a register knock in a cell its not always that cell timing reduction that gets rid of it. its the cell before . normally the cell but sometimes
