STFT question Should I wait for my STFT to zero out before tuning my ltft's? I read somewhere, that your stft will zero out and it will give you a more true reading. Is this correct? If so I've been doing it a bit wrong,

Yes. Here is my own method.
Upload new tune
connect scanner, reset fuel trims
drive for 30-40 min in various loads/rpms
turn on scanner again and open histogram and try to hit as many LTFT cells as possible
after I've hit as many ltft cells as possible, flip it over to stft cells and spend as much time in each cell zeroing out stft so that the ltft for the same cell is learned.
I've had alot of sucess doing it this way. On one log my ft's are pretty much in line, then I just spend some time tweaking it.
