Missing parameters in tuning tool?

[QUICKSILVER2002]

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.

Have you downloaded the latest calibration files (version 7.62 - August 23rd)?

Those parameters are in my tune file.

I had a nagging, persistent problem with Idle. 2001 Vette. 239/251 cam. 90 mm TB, Fast intake and headers.
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.

What operating system?

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.

Duh, I did not read the instructions very well. I did not realize that you had to download the calibration separately.

I did that and I’m good now.

You guys rock!!!!

What are you guys setting your A/C airflow ramp in and out? (Grams per second) B4354

Mine looks like this:
Ramp in
nm Value
0 1.0
5 2.0
11 3.0
16 4.0
22 5.0
27 5.0
33 5.0
38 5.0
43 5.0
40 5.0
.
.

And Ramp out:
All values read 0.00

Also related to G0108 A/C Torque loss and G0109 A/C Torque loss-IAT

Trying to keep my engine from dying and surging when I turn on the AC compressor. It kicks on and off and wont blow cold unless I give it a couple hundred more rpm. If I am in park it will almost always kill the engine or surge up and down really bad as the AC compressor comes on and off. I added rpm to the B4603 desired idle speeds in the "In-Gear A/C On and In P/N A/C on" columns. Gonna go see if that helps.
