SS, I have also noticed, but not verified, that even with the TC activated, it will get into an idle mode if the RPMs get into the range of desired idle. Now, I have disabled TC completely because either you would need too little airflow as the rpms hang a lot and on the next day you would need a lot more airflow or it stalls. Then you have a "rolling idle" that varies from time to time from stalling to 1100-1400rpms... It gets annoying.

I disabled TC and let the idle do it's thing... Now, I have only done this with this car as it has been a REAL pain because of the stalling issue. As of now, it doesn't stall... or at least it hasn't in the past couple of days.

The best results where to adjust b4504-6 to make Filtered RPM airflow come on first and then DAC and LASTLY the learned values. I did this because with the filtered RPM airflow, the way I see it... It will control the rate of deceleration of the engine when you dump the clutch or whatever. Then the DAC will have "different" values if you have the A/C and then the learned values will do it's thing to bring the idle nice down and safely...

THus far this is the combination I have used to make it work.
