IAT and idle airflow
Is there a table that controls how IATs interact with idle airflow?
Here's my problem. When I drive in to work in the morning, my hot idle IAC count is around 25. When I get to work and pull into the parking garage, every time i come to a stop, the motor almost stalls until the STITs jump up and the IAC counts hit about 35. Im rather surprised that the cooler temperatures in the shade would have that great an impact on idle airflow. Anyhow, is there a table that will let me scale the efffects of IAT on idle airflow?
Thanks,

The "idle aiflow parked" table is in g/s vs. IAT, while the "idle airflow" table is in g/s vs. ECT.
I'm using EFI live, so the table names may be different in other programs.

yeah i know all i haev read says this does nothing. but why in the world would we need a table to set the iac when at park? i would think once the key turns on it sets it to the right spot so why do we need it? u know. just try and add 20 g/sec and see what it does at idle. i have not done this yet but i wonder what it will change, if anything. all i know is when i set the values from 20 and up to 10g/sec it helped a lot of issues out. i know all the writeups talked about setting it really high and i have no idea why you would need to do that

Anyone else have any information about wether this is used during normal running operation?
