Avcr Solenoid Help Needed

Hi guys,

I sent my 34 off to be tuned and for a secondhand avcr to be installed.

The car was tuned with a safcII and i was told that it wont produce more than 6psi boost.

It appears the avcr is not doing anything..

the display etc is all working but it looks like the solenoid is not responding to anything..

So they said SOLENOID is busted.

now has anyone heard of this occurance.

I have found a solenoid on Nengun from apexi for an AVCR.. so I can get a replacement part at around $130.

Are there other solenoids that will do the job..

Are there any tests i can do to make sure the solenoid is baked. ?

anyways 6psi tune produced 237hp on an auto 34.. so i guess its a start

Is the solenoid all hooked up properly? If its working, u can hear the avcr solenoid tick away, its loud enuff to be obvious when driving n boosting. A dead solenoid is possible, the electrics of an EBC seldom fail, if anything dies, its usually the solenoid. And no u can't run other solenoids, it's already good that Apexi sell just the solenoid cuz some others don't and they will need a whole new ebc. Go with getting a new solenoid from nengun if the solenoid's dead. Apart from the long waiting time, nengun's prices are prolly the best u can find around.

Hi,

check they have put the hoses on the solenoid the right way around (COM to wastegate and NO to IC piping) also problem could be pressure sensor but i dont think so... if it's hooked up right turn the car on and see if you can hear it working (might be hard to hear)

Don't really know what else, hope it helps

So i guess i will grab the install instructions and make sure the TUNER has installed it correctly.

Hopefully its something as stupid as that *fingers crossed*

But if its all the right way i will grab the solenoid from nengun.

Does anyone know if the AVCR actually can report is something is wrong?

Is there an electrical test i can do with a multimeter to see if the avcr is actually pulsing the solenoid.. I dont know too much about multimeters.. but could possibly figure it out

Just put 12V across the solenoid and see if you can hear it.

If you cant, then test the output of the AVCR to the solenoid using a multimeter. (Check for voltage across the terminals when it is connected and the AVCR is meant to be sending a signal to the solenoid.)

okay finally got round to doing this

the solenoid ticks when i touch 12v to the pink wire and ground the black wire

so if it is ticking this means it ISNT dead... is that right?

I moved the pressure sensor to just where the fuse box it.

so its a short run of hose.

it was mounted in the corner nearest the driver in the engine bay.. so was at least double the length before.

the BST reading on the avcr when the car IS boosting.. never reaches positive MMHG

so i am going to double check the wiring to the ecu...

could the pressure sensor be Kaput.

Sounds like a wiring issue.

Car is actually making boost right?

Now, you have an external boost guage right? And it shows 6PSi?

If you get the car to say 3PSi, does the AVC-R read 00mm-hg or does it actually read something less?

If it's less then it sounds like a setup issue.

If it's 00mm-hg, then it sounds like the boost sensor is sending out the same signal as soon as it hits boost.

Like it's maxing out.Strange.

i am fuming right now

I paid a workshop to do this for me..

anyways went through all the instructions step by step

the sensor was NOT set correctly..

manual says DO NOT USE 3 times for the other options and tells you which one to use..

so i changed it.. and walla..

now its boosting and the solenoid has activity

the duty cycle was set to 90%

car didnt like

have dummed it to 30%

i am taking it back to the TUNER rofl

I am going to ask for a retune as i paid good money the first time for an incorrect job

thanks for the help lads.. i may post up a result.

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
