Any Idea how to hook up the GM solenoid?

 

I used to have a vacuum line diagram from Hondata which should the recommend setup from a vacuum hose perspective but I cannot find it at this time. You can't really see my setup from this pic (solenoid is mounted just behind the intake and on the passenger side inner fenderwell area):



but you have one vacuum port (towards the radiator) that is basically venting to atmosphere, one port (towards the firewall) that goes to the intake manifold and a third port (towards the firewall as well) which goes to the turbo. As far as the power wire goes, you run the single power wire to the Hondata unit and it goes to ??? pin. I don't know which pin it is off the top of my head, but if you search Hondata's website I am sure you will find the info.

 

Yeah I am looking to find out exactly which pin it goes too I think inthe program it says B21 I was trying to make sure that its the right one. and I thaught that the vacum line that went to the vented side of the solenoid went to the top part of the wastegate?

 

You are correct about the wastegate vacuum hose.

 

Don't bother with the GM solenoid,for the same price or cheaper you can get the far superior AEM/Mac solenoid.

I picked one up a few days ago for less than $30.

 

 

That's some bogus information. Many boosted members on this board use the GM boost control solenoid and love it.

 

I'm currently running a K-pro. Swapped over from an AEM EMS. I wouldn't go back for a second.

 

A friend of mine had his GM solenoid fail on him last week,he would have popped his motor if it were not for his boost cut he had set on his standalone ECU.

So instead of replacing it with the same part that might fail again,he replaced it with something alot better at a cheaper price.I currently have the GM solenoid hooked up,but it's coming out pretty quick and being replaced with the Mac valve I recently purchased,even though there's nothing wrong with the GM part at the moment.

Which solenoid are you using?

 

Hondata just released a higher quality solenoid in order to correct the failure that sometimes occurs with the GM product.
