My thought. How does it sense and control idle? The EFI on my '88 Carrera had a microswitch that sensed when the throttle returned to idle position and activated the ICV. Very simple, just a microswitch that was pushed in by the throttle linkage. If yours has a similar switch, you could tap it. Otherwise you could just rig up a microswitch that was pushed by your throttle linkage when at idle.

Edit: here's the microswitch used on the Carrera, you can look at the diagrams to give an idea of what I'm trying to explain.
