What is your idle (when ported)?
What's the idle you guys are running on, and what type of idle setup do you have?
I'm running 1500 RPM on the 3 first values in the PFC, and 1050 on the 3 secondary values. Used to have 1100, but it runs fine on 1050 also. Can't go any lower than that.
My idle setup includes disabled (removed) airpump O2 Feedback control and Idle Ign function in the PFC. It's using the hidden idle map at the moment, but I'm planning on going with a full manual idle setup that is better tuned towards 14.7 AFR. Current setup runs rich at ~12.6.
Car is streetported with lightened flywheel.

Those values have different functions as detailed in the manual.
"F/C" is fuel cut and is the rpm when the injectors turn back on after lifting off the throttle if you let the revs drop that far before getting back on the throttle. It is not an idle rpm.
The bottom three are your idle settings.
******
Since I do not use the ISC to controll idle rpm and idle timing, my bottom three are at "0". My manual fixed idle with full A/C and electrical load is 900rpm. Without any load, it is 1150 rpm.

have a just thrown in rebuilt engine.
Aggressive streetport, idles between 900-1050, its set up n 1050rpm.
as i started the car, i have done the idle learning process.
well, there is a idle controll function, the manual says, it should only turned off, if checking the ignition timing. but i wonder if i should turn it off because of a ported engine? wrong or right?
like says above, my idle is jumpy, some kind of a mild halfbridge brapbrap
