not common idle control possible??

[turbojoy]

I have an engine with the following idle control valve:

It is controlled by reversing polarity.
Original it is controlled in this way:
rpm to low: on
rpm to high: on with reversed polarity
rpm at setpoint: off

Can this be controlled by Vems?
If yes, how? (settings in VT)
It should be possible with the stepper outputs but I cannot figure out the setup in VT.

Any help is welcome!

Hello Turbojoy,

An idle control type like this (push-pull) is not supported by any configuration, i would recommend changing to a more common Idle control valve, for instance 3 Wire BOSCH IAC.
If you have some additional information about your idle control valve, brand, part nr, perhaps spec / picture, i could investigate if alternate control methods are possible.

Best regards, Dave

Hi Dave,

Yes, will post pictures only I don't know how to do it on this forum.
Can you tell me how to do it?
Have you read my post in the project section?
I cannot use any other form of idle control valve.
The engine/car needs to stay in original form as much as possible.
It has ITB's so an air bypass controll valve is not possible to use.
The idle controller now simply pushes the throttle open (like an actuator from a cruise control).
But your answer is clear: not possible with Vems for now.
I will build my own controll logic then with a pic/basicstamp with as input a pwm signal from the Vems.

Thanks for the answer!!
