Having the usual idle problems with a SD tune and OL with STFT. I have a cam with high overlap and it comes down to an idle perfectly coming to a stop in pure OL reading a higher AFR than stoich. With STFT enabled in OL it runs very rich and dies or hunts coming to a stop. I want to run OL with STFT only above idle. I read the threads where you change tables so from 800-1,200 RPM you command PE with 0 throttle position at idle it is supposed to go into OL. It doesn't though and actually goes very rich. Some table is over-riding it but I have no idea as it does OL PE fine at high RPM. I have a '04 GTO LS1 so it has the "Australian computer" with lean cruise and such so I don't know if there is something different there. I am also running the HPT custom SD programming if that makes any difference. It has me scratching my head.
