The only issue I have at the moment is the annoying rolling idle. Never stalls but just sounds like a clunker with the idle slowly up and down. It idles best at 875-885 and the IAC counts are about 120ish as this tune is setup for. I was messing around and I manually set the IAT to 90 counts and its sounds great with the idle around 790. However I can not keep it there. It will start an endless occellation of idle that will eventually die. So the tune posted is a working tune but I feel that if I can get the little slow rolling idle addressed I can move the idle speed down a fuzz and it will idle clean with no corrections or rolling. The RPM's seem to vary with the O2 oscellation at slow engine speed. Drives great above 40mph and 2000 rpm.
I cleaned it up a ton by taking about 50% out of the O2 Error in the Closed loop tables. But I want to focus more on the parameters that are effecting the O2's at idle only.
Any pointers or tips will be great.
Thanks!
