AC torque settings Anybody know anything about the ac torque settings and the airflow required from this? It seems that the setting somehow affect the IAC settings during idle functions. Anybody know about this? What are your thoughts/comments.

From what I can gather, its all torque based around g/sec airflow meaurements. So, monitor your AC airflow PID and adjust the AC airflow torque vs IAT and inertia torque up or down to suit.
The AC airflow adds to the base running airflow. Ive seen with big cams the AC can really stuff up the idle and coast to a stop because they draw less vacuum, so less torque. For cammed cars, I would guess if there was a starting point for measurement, take the stock manifold absolute vacuum from the cammed absolute vacuum and modify the above AC airflow tables by that percentage number.
