By the reading in the V3.57 introduction I suppose that this Board already has that diode and it also supports high current from the IAC:

"The fuel pump and fast idle solenoid outputs are now driven by a power driver IC (Integrated Circuit) from ST, the VNS3NV04D. This device will drive up to 3.5 ...

It's is from a GM 2.0 16v. Meanwhile I got the electrical sheet of that car and the IAC gets 12V from the main relay. The picture is in attach…
Thanks

Ok... But the problem is that I got one from the damaged car and I didn’t saw it running. And what about the V3.57... what do you think?

Hello,

I found a website that sells the wideband bosh sensor and a controller. I think it is in UK and I also think that as a pretty nice price.
From the specification I think it will work fine with MS. Has anyone ever tested this controller? You can check it out in Trigger-Wheels.com

Thanks

Thanks Matt.

I have another question. I don’t know if my IAC is a fast idle or a PWM idle but I think the wiring is the same isn't it? How should I know what it is? Beyond that, I suppose that stock V3.57 can directly control this two IAC?!

Thanks again.

My VR sensor has 2 wires and the shield. Is it correct to connect the signal wire to pin 24, ground to pin 19 (with the other sensor ground) and the shield to pin 2 of the DB37?

I have a MSII on a V3.57.

Thanks to all,
