questions

[keving]

Pardon the newbie quest, but:
My ltft range from -2 to a max of -10, got a question, how do stft coem into play? I read that you want to start logging after the stft chill, but underf what circumstances do this start being close to 0?
also, how can I tune wot (fuel) w/o a wide band, I reads you can shoot for .890 or so, but my logs fluctuate so much, this seems like an imposibillity. Any ideas?

STFTs may not sit still, especially on a late F-body where
the fuel trim cells are defined to cover very broad RPM
regions. As long as they're smallish, single digits, they
will be updating the LTFTs pretty slowly in my
observation.

The O2s are only relevant (to power tuning) at WOT.
They bounce all over in closed loop. Look for cell 22.
You need to log FTC, RPM, TPS and the front sensors.
Then sort the log by FTC, grab the FTC=22 bits, and
then sort that batch by RPM. This should show you if
you have enough PE, and if you need to change its
slope relative to RPM (like if O2 output starts to fade).
