I would use KFKHFM for the tweaking from now on...
Maybe I don't know what I'm doing but when I underscale the MAF I go down with MLHFM and up with KRKTE the same amount.
So for example I'd multiply MLHFM by 0.8 and then multiply KRKTE by 1.25 to get it back up where it was as far as fuel / g... It seems to work for me *shrugs*
Hows your STFT loking at idle after being warmed up fully?
Well, yeah. Shifting MLHFM was "OK". My Fuel curve FOLLOWED the requested when boost was reasonable, under 22psi. With tweaks to KRKTE I was able to get them to line up pretty good. After 22psi, the only way I been able to get fueling to go proper again was by underscaling the load in the areas needed. KFKHFM was the only table I saw that was able to do it this way. It took me a while to figure it out though. I would add to kfkhfm thinking it would add fuel, and it was actually making things worse. I really couldn't tell until I had a bunch of logs to look at. I even used KFLF alone to add fuel and it didn't do it as well as just by underscaling the areas needed. I found that when I underscaled the MAF via MLHFM, I needed to do a lot of other changes to the maps that dealt with load.
I guess we are technically doing the same thing. Its just that you are doing it to the entire MAF/fueling, and I am doing just the offending areas.
I haven't been watching my STFT at idle much lately. Last I saw, and I am pretty sure it still holds true, they were around +5-8%. I just left them alone since My focus has been the WOT/high boost part. I didn't want to dial in the idle while I was making all those changes elsewhere, which would probably in one way or another re-screw up my trims.
