I'm using Motec so I could pretty much run anything.

I guess what's throwing me is the term stepper motor used with valve. If I understand correctly, the stepper motor is just opening the valve in an idle air control valve.

The Clewett IAC looks nice and for $200 with all the parts, it's a bit more affordable than the $300 Bosch unit Motec sells.

I was hoping to avoid adding another bung to the intake, but I guess that's the right way to go.

Do you think it'd be OK to put the bung on the IC outlet tank rather than on the tube from the IC to the TB? I think it would look cleaner and be easier to connect and disconnect the hose.

I notice the Clewett valve has 4 wire inputs. Does it use all 4?
