For what it is worth: When I disconnect the ICV on my 3.6 the engine stall right away. The 964 ICV is a spring-loaded device. It gets only one signal with varying duty cycle to control its position.

I created my own OBD-1 diagnostics port using a LEMO connector. And I then fabricated a custom cable to connect to the hammer. Works perfect.
