I experimented with it by setting it at 80 across all temps to see what would happen. I found that on a cold start (30F) it would stumble for about half a second until the IAC went up to achieve my idle setting (1500rpm), and the IAC ended up at about 120.
I used Bob Cunningham's procedure from another post by starting the car at various temperatures and then watching where the IAC wanted to go to maintain idle. I used those numbers to set up the IAC Start position. It worked great!
And Bruce, the curve ended up looking almost exactly as you recommended, with about 120 at 0 degrees ramping down to 80 at about 80 degrees.
Thanks guys,
