 Jaycar IEBC and Autronic solenoid

Hey guys,
This one goes out to anyone who can answer the questions, or particularly Teh Witzl 
I've got the Jaycar IEBC wired in, and the turbos plumbed into the Autronic solenoid. The line comes from each compressor cover, to a T-piece and into the "P" or inlet side on the solenoid. From there it goes out the other side, or port "2" (? from memory) on the solenoid, to another T-piece and to the wastegates.
Now, the question I raise particular to the Autronic solenoid is it has the 3rd inlet/outlet on the front of the solenoid which when the solenoid is off is connected to the outlet side, and when switched, is connected to the inlet (once again, from memory). What do I do with this?
There also needs to be a vent to allow air built between the wastegate and the solenoid to be evacuated according to the manual. Where should I locate this given that when the solenoid isn't switched, port 3 is connected to port 2 which is this wastegate line.
I'm thinking put a fitting on port 3 and blocking it off, then placing a vent in the hose between the wastegate and the solenoid. That sound like the right way to do it? I've consulted the Autronic documents, but it's setup is like a "conventional" EBC.
Cheers,
Nathan

Yeh, SiliconChip wants to set it up differently... follow its diagrams of a vent between the solenoid and wastegate.
It does then sound like the 3rd port should be blocked.

Their way makes a whole lot more sense, playing around with the car before the boost controller was properly set up was an experience, kept having to back off because boost would come on a WHOLE lot faster.
I'm going to get a fitting to restrict the flow from port 3 a little, if that doesn't work, I'll block it off entirely and mount some sort of vent in the line between the solenoid and the wastegates.

Theres a few different ways you can hook the extra port up.
1. Straight to atmosphere
2. To atmosphere via a restictor
3. To the intake pre turbo
4. To the intake pre turbo via a restrictor
Most people just leave them running straight to atmosphere.

So you recommend I just leave port 3 unblocked and not install a vent?

If I had a camera i'd grab a pic of my setup as it runs currently... my apexi (if i remember correctly) has three ports, common, normally open, normally closed. Just block off the normally open one, and plumb the normally closed to a T piece. One side of this should go off to another T piece to split the wastegate lines to the turbos, and the other port (say, the middle port) should go to a restrictor of some sorts. I just used a GFB bleed valve insted of that first T piece - works a treat and is adjustable!

nathan - there are a few ways i looked at to make the IEBC work with the Autronic solenoid.
What i did with teh pimpy AE71 was the following:
# boost source from turbo compressor outlet to COMMON of solenoid.
# block off the NORMALLY CLOSED port of solenoid
# NORMALLY OPEN outlet of solenoid to T-piece.
# one side of T-piece to wastegate
# other side of T-piece to small "bleed-off" opening
The idea of the small bleed is so that when you shut the throttle and thus create vacuum in the intake (causing the solenoid to block off the boost source to the wastegate) you dont get pressure built up to the wastegate line - otherwise your turbo would be slower to spin up again for the next gear.. AFAIK.
I would have to read up on the kit again to remember how i set mine up inside the kit..... but of course to program it you want 100% D.C. output at low input levels... and the output D.C. to decrease as you approach the desired boost level.
I remember there being a setting on the circuit to "invert" the output.
THe reason i used the N.O. port on the solenoid was in case it broke or lost power.... cos if it were on NC port, you would have zero boost control....
here's a dodgy diagram.
