fast idle valve Control

Post by toon3 »

MS1, Extra V-3

The canister purge valve I am using is normally open. when the engine is cold it wants to close the valve and then open it when warm.

How do I change it so it applies voltage and closes the valve when warm?

I've looked in the Manual but can't seem to find the answer.

If the purge valve is an on/off valve, use a generic on/off output instead of the IAC.

Thanks Matt,

I have it selected in TS as B&G on off. I think this is correct.

I need it to open the valve when cold, close when warm. Right now it does the opposite.

Use one of the programmable on/off output circuits for this valve instead of FIDLE.
