Make sure none of your clutch/neutral switches don't stick. There is a an indicator available in TunerStudio, under "Predefined indicators 2", called "Trans Eng".
This should be green whenever your transmission is disenaged, ie either the clutch is depressed or the tranny is in neutral. It should be white when driving.
If you don't have the green "trans eng" indicator on, the ECU won't enter closed loop idle.

I mean that is probably true. Honestly I know you can make your idle better then it is, I just do not know how. My 92 has a shitty idle and I attribute that to it being an old rusting POS, but I am still young and just do not care.

I was thinking the exact same thing. I know I've designed the whole system around my car, maybe the A/C clutch on my car engages slower than on Hustlers? I need to make the system adjustable.

before i started using timing correction at idle, ive been using 450ms delay with 11.5% duty increase.
now im only adding like 7% with a 275ms delay -- because my timing increases along with the duty adder to kick me back up to target.
should be able to easily see if the duty cycle jumps up by X (whatever you have programmed) as soon as you hit the switch to make sure the function is even working.

I'm pretty much ready to "deal with it" by jacking the idle screw to 1100rpm so I can drive this thing in comfort all summer. I'm tired of nursing the car when accelerating from a stop and constantly roll-starting off the clutch in traffic.
