How can I test my Idle Speed Valve?

[ZyBeR]

Hi,

I've just hooked up my M880 to my Evo VIII (4G63) engine. Is it possible to test the ISV like we can with other AUX outputs? I tested to just click start bu nothing happened so I guess I'll have to do it some other way, but U just don't know how?

Is there any settings that I have to configure for the OEM Evo VIII ISV?

You can't test a stepper motor this way, you will need to test it using the parameters in the ECU. AUX5 needs to be set up for Stepper Idle Speed Control.
