That diagram just confuses the crap out of me! Why wouldnt you tee everything together and just run one silnoid for simplicity?
From there the 2 ways the eboost diagram reccomends to hook them up is:
port 1: is connected to the gate side port as well as pressure source(recomended non vaccume)
port 2:top port on gate
port 3: vent
OR
port 1:top port of gate
port 2:pressure source
port 3:side port
(this one will increase boost level beyond gate spring pressure)
It looks as if you were going for the first hook-up but I dont understand the tee's you have near the connection of port 2 at the top of the gate....if you had a open port there it would mess things up.....as it tires to apply pressure to the top of the gate comming into boost, then bleeds it off out of the vent after desired boost is achieved.

It allows the gate to vent properly (no pressure against the membrane) when the boost controller is turned off. Normally the top port is open and the bottom/side port has the boost reference when a controller is not used. When an EB2 solenoid is off, no pressure can escape through the solenoid when it's hooked up 1 to 2 .

When the diagram was blank paper it was even more confusing...
Didn't run one solenoid (almost tried it to see) since the EB2 instructions said to run two solenoids with external gates. One solenoid was fine with twin internal gates.
Two things are happening. Some reference is being cut from the bottom/side port when the solenoid is active. A small amount of reference is overcoming the tee at the top port and is applying opposing pressure against the gate to help keep it closed.

Also we used 1 controller for 2 wastegates before.No problems.

The E-boost solenoid has the vent port built into it, by having the "open T" between the top port and the solenoid you are not allowing it wo work properly. When the solenoid is on it connects the top port to the boost pressure, when its off, it vents that line to the built in vent port. The Eboost 2 uses PWM to rapidly cycle the solenoid to mantain the desired boost.
You configuration is most definatly wrong.

It may be wrong, but it's what Tial recs so we'll see. Their guy is adament that its needed to "stabilize" the pressure signal with the controller on. Looks like it would bleed off the signal but he claims it will overcome the tee and still apply pressure to the top port.
I think the configuration is correct. Only question I have is about the vented tee since the solenoids do back vent. Easy enough to remove the tee at the gates if it doesn't work at high boost.

Just called Tial back. They said the configuration was correct. Also said if the solenoid back vents (like an EB2), you could run it with a vent tee or without a vent tee if the boost control was stable. I'm going to try it with the tee just to see if it works....pop them out if it doesn't.

Actually Tial specs a 6mm opening.
That "looked" too big so I tried a 3.8mm.
If it works without the tee I'll probably give up the boost leak anyway....
