Fast idle Solenoid

[chris989]

Hello All,

Does anyone know of, or has ever seen a fast idle solenoid for TBI set ups. Think of a tow/boom truck or ambulance. There are a multitude of industries that need to manually increase the RPM to operate. What did they do in 1989 for this.

I have had enough with my IAC and computer. I am convinced that somewhere within the idle logic my computer adds steps i do not need.
The motor is running perfect, idles perfect all day long, and one variable will click and the IAC wants to idle at 850 warm and 1200 cold. When i gear at a red light, I can watch the IAC add steps trying to reach 850, so much it wants to drag me through the intersection.

Ultimately i would like to disable the IAC parameters and have it only operate steps/coolant and call for AC but i can not figure out how to turn off all of the other layers of garbage.

Until then I have zero'd out my IAC, unplugged it and set the idle to 725 in neutral. I idle at 650 in gear and it is a dream come true. So until i figure out the idle logic or deem my computer defective, I was thinking of adding a Solenoid. setting it to activate for cold start and AC.

Anyone ever see one on a TBI.
