Missing parameters in tuning tool?
I see this in the "more info" in the scan tool.
Short term IAC airflow correction in drive with AC on.
The short term idle corrections are controlled by the following Tuning Tool calibrations:
{B4512} Filtered RPM Airflow Correction
{B4514} Learned Airflow Correction
{B4515} Direct Airflow Correction
But these don't seem to exist in the tuning tool. What am I missing. Do I need to do another read to see them?
Also, I'm looking for a way to control the base airflow added when the AC is on. I thought I saw something once, but I can't find anything now. Any ideas. I think it was a TQ number to drive the AC.

The electronic throttle idle would periodically learn downward 4-5 g/sec and 4-5 % TPS. It would drop the TPS from 11-13% to 6-7% and Desired airflow from 11-12 g/sec to 6-7g/sec. It was driving me nuts!!
Added air for the fans -B4301, B4302 (.75/1.50 g/sec).
Added air to the "Idle Learn AC Limit High Table"- B4326 (4.00 g/sec)
I had already increased my "Idle Learn Drive Limit High"- B4324 (3.00 g/sec).
Problem is cured!!
FWIW.
I don't think AC Compressor and Compressor TQ tables are in FlashScan - yet.
Hope this helps.
Cheers,

Ross just sent me the details for ramp in/out airflow compensation for A/C clutch. I added them about 30 minutes ago, so they'll be available soon.
