It would appear I don't have this table as the only IAC related thing in my XDF is "IAC Position vs. Coolant Temp". My understanding (possibly wrong) is the IAC vs. CTS is only used during Open Loop. However, open loop does seem to be where most though not all of my stall issues take place.

Looks like it is in my best interests to go through the IAC procedure anyway and see where I land.

Currently it is mostly the same as the stock BMCB with a couple changes.

Deg C / Deg F / Steps
-40   / -40   / 95
-16   /   3   / 78 (Stock BCMB value is 90)
  8   /  46   / 51 (Stock BCMB value is 32)
 32   /  90   / 24 (Stock BCMB value is 12)
 56   / 133   / 10
 80   / 176   / 10
104   / 219   / 13
128   / 262   / 25
152   / 306   / 45

Is this table read as a base value, or in other words, "no less than this many steps" when the table is being utilized?

While I don't know how the car utilizes the table completely, my car had some modified IAC table and I had a stalling issue, changing the IAC all back to stock fixed the stalling issues I had
