Here is my calc pid file for idle tuning. with this file and a map you should be able to dial your idle in to a tea on the first try from a cold start to operating temps.
The correction is directly applied to the Airflow idle table for both PN/in gear and ac on and off. To use these pids with a map set either a row/colum to rpm =8000 and use the respective ECT values to build your tables. Happy idle tuning
