What is the formula to convert HP Tuners airflow to IAC counts? Just as the subject says; what is the formula used to convert HP Tuners airflow into IAC counts? This would be very helpful information for tuning cars that have drilled throttle blades, or adjusted set screws.

I don't think you can get that. IAC is just a servo motor,
opening a hole - the airflow comes from the engine air
sensors / calcs, mostly the speed density part at idle.
The IAC is controlled to get the right airflow, closed loop
fashion, by indexing the count up or down until the right
value is reached.
