I use a GM type stepper motor (and the Clewett adapter) plus the software to control the cold start. Depending on engine temp, the software adds a shot of extra fuel during cranking and decays per the number of initial engine revolutions. The IAC is open about 200 steps when cold (at operating temp, its open only 18 steps). In addition, the engine warm up table adds a high percentage of fuel and decays up to 60C when it shuts off completely.

You probably already knew most of this, but I thought I would explain how my system works. There's nothing extra hanging off the engine to accomplish cold start.
