HOW TO - Control boost using ECUFLash and 3 port GM boost solenoid
yeah, as long as the NO (normally open, IE you can blow through it with no power applied to the solonoid) port is connected to the WGA you are good. Obviously the other hole you are connecting to boost source should be the other NO whole, and the NC hole should be connected to a filter, your intake, or open air.
Normally there are diagrams somewhere that say something like "NC Port 1-3 NO port 2-3" or something along those lines

ok basically it looks like
AI = Air intake, WG = wastegate
to work out which way, blow into the metal (turbo compressor) thingy and the air will come out of one of the plastic thingies, that goes to the AI.
Code:
to WG ------|------|
| GM |----- to turbo compressor
to AI ------|------|

The thicker line on the bottom is coming from a nipple I put on my LICP.
The top, thinner line goes to the WGA.
I mounted mine to the side of the radiator, so it was a little more hidden.
Awesome, thanks for the pic.
Has anyone noticed a difference with recirculating the vent outlet and just letting it VTA? I had mine recirc'd at first (Perrin solenoid) but removed the line during some troubleshooting. I plan to put the line back on but I wanted to see if anyone had experience ...
when i blow into the metal barb...air comes out of the nipple that does not have the filter thing. According to tephras diagram the one with the air comming out goes to air intake and the other goes to the wastegate. but in schiedes pic its reversed.
The metal port goes to a pressure source (compressor outlet pipe for the stock/variant turbo guys), the port that does not have the foam filter on it goes to the wastegate actuator and the port with the foam on it goes to the underside nipple on the induction tube (take off the foam).
If you vent the foam port to air, keep in mind that is air that has been read by the MAF that you are venting to the air.

If you still have a nipple on the induction tube, you might as well use it.





Its all good
