Grant, it does not require you to tell it when to turn off. That type of air valve was designed to work by itself independant of the ecu. It turns off based on the heat it sees on whatever you've bolted it to. when it gets up to temperature it throws a switch internally and turns off.
This is how they worked on all early bosch systems such as motronic. The fast air valve had nothing to do with the ecu. it is given power all the time and it turns itself on and off based on its temperature. try it.
that is why you are getting the situation you describe. ms is never going to have full control of this type of valve. If it were an on-off vacuum switch, temperature of the valve itself never matters, it is only based on water temp and ms can turn it on and off as it likes.. you are always going to have 2 situations where ms can't control the valve (ms cold, valve hot and ms hot, valve cold) as you basically have two on-off switches in your circuit.

Andrew i get what your saying, however on the Relay board not the ms it has a fidle point, when the ms gets out of warmup it flicks the power off it from the relayboard, this may be a bit different than running just ms and the idle valve. I wasn't aware it had an inbuilt switch we have another one running here with a ms and im sure its fine from the ecu.
I'll look into it a bit more

yeah basically what i'm saying is if you want the ms to control the fast idle (relay board or not) you have the wrong type of valve. thats not to say you won't be able to get it to work how you have it, as you say by putting it somewhere hot so effectivly its always on and ms can then switch it on and off.
that type of valve is meant to work independent of any other control ie connect up + and - and put it somewhere that gets engine heat. it will then switch itself on and off based on the heat it sees. try it and see what happens..

Solved the coolant sensor problem, cost me 10 cents to fix .
You just change the resistor in the MS to suit the sensor

Well so far so good, its on the road and driving, have to play with acell enrichments, the ve is basically sorted.
After a 45min long tune yesterday and drive around mountains at all different revs gears it was running fine. Called into pizza hut on way home and forgot to save the file DOH.

Well after a bit of tuning on Sat and some adjustments to the accelleration enrichments its all fine and running well. Nearly done about 200ks in last 2 days, trouble free, copped a bit of traffic today in and around the city managed fine apart from me sheetting bricks the whole time, but runs like a dream.
You can allmost feel the economy when you in 5th gear pulling about 40 -50k -60 and its doing about 1400rpm ( near where the carbs used to idle at) it sounds like your rolling with the clutch in its that quiet. The bonus is i guess you can still plant your foot and it will do the same as the carbs used to.

Looks really good grant.

i think its about time you put up some more pics of your car!!
full engine bay shots and some side on shots and interior from the other pics it looks really well done!!

I'll post some more shortly, of the disc setup.
after all the front end gear goes in and its lowered
