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.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.

      Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.

      @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
