AVCR Issue - help needed

I have just installed an AVCR controller on my Evo 8, however when it goes on I get no boost readings and I do not hear the solenoid fluttering (as I used to when I had one on my Mr2 Turbo).

I have connected the hoses as follows:
Actuator to COM on Solenoid
NO on solenoid goes to pipe between dump valve and intake surge tank (I have also tried the NO going to the inlet turbo feed.
Blocked off the Inlet turbo feed
NC is left unconnected and not blocked off

Also the other sensor I have installed facing down with a hose going (with the paper filter installed) to a T between the fuel pressure regulator and the intake surge tank.

Have I done something wrong? when I go on the controller and go to test sensors, it returns a voltage reading from the boost sensor.
The rpm is reading correctly, the TPS reading seems to be in order, the speed may be a bit off.

No boost readings ...but is the car boosting as it should ? You just have no reading of boost you mean ? :)

Its boosting normally as i can check on the factory gauges, but i get a fixed 0.00 boost reading constantly on the avcr and i get no clicking sound from the solenoid.

At least its not so bad then ...boosting fine :thumbup:
Must be a link from sensor .......check the boost line from pressure sensor (that oval shaped thingy :mhihi:)...could be the issue ? Or sensor itself maybe :smthumbup

Check a pin has not pushed back on the black connector

Is there anyway of testing the sensor prior to buying a new one?

Could I hook it up a different boost line?

I will check re the pin, the funny thing is that in the sensor check on the controller the pressure sensor is returning a voltage reading, wouldnt that imply its working or?

Bridge out sensor 5v feed to signal see if it reads full boost, check 5v feed to sensor fm ground for 5 v

What if it's making a poor connection? I had one and I think it was blue wire, pin had pushed back on connecting

Cheers guys will check your suggestions out

Checked the pins all are ok :(

Will check connections with an ammeter to check that all wires are intact following the install.

Would wiring the ground wires to the same point on the ecu harness as opposed to two different point affect anything?

Could it be the cause?

I am not sure about it, but the manual recommends 2 different points for the ground wires. You must do it.

If you could try another main unit i would do it.
I got crazy trying to work my first AVCr (2nd hand) and i finally had to buy a new one.
My problem was the turbo always spooled like stock.
The problem was not the solenoide (i bought a new one to test before i bought the new AVCr)
I hope this is not your problem.

Yep I will try that too, funny thing is that today I started to get some readings coming and going, tomorrow I will reconnect the earths to two separate points and see what happens

Thanks for your help guys :)

Issue has been sorted and controller is functioning as should be.

It was something stupid an incorrect hose connection :s

Just a wee tip here I wouldn't t anything into the hose for the fuel reg pressure best to take readings from the manifold it's self
Any failure or leaks in the hose for the fuel reg could end very badly :)

Noted, will make the necessary modification ;)
