i just checked it is infact connected properly to the solenoid does it mean that the solenoid is not working then?

is there a chance that it might not be getting enough power to control the solenoid becasue i connected the power line which comes from the greddy unit to the line which came from the back of my cigerette lighter?

Edited by Deathvalley

i figured out the problem.its the valve uni harness.the white thing that connects to the greddy main unit came right off.probably thats why it wasnt controling the solenoid.

is there anyway to fix that?or should i just order a replacement?

can anyone tell me how to check the solenoid.i want to see that it is working properly before i spend any money on this thing.

Can you cable tie the plug to hold it in?

To check it is working connect a bike pump to the gauge pressure line for the controller and with ignition on pump some pressure into it .

You should hear the solenoid pulsing quickly.

If it were me, I would open up the main unit, solder on a couple of wires to the pads where the external socket is, bring those outside the case to a new multi-pin connector from Jaycar or similar, cut off damaged white plug and replace with matching connector from Jaycar. Job done. 15 minutes plus trip to Jaycar.

@gts boy man great idea.

i checked in jay car

http://www.jaycar.com.au/productView.asp?ID=PP2020

the small one is the picture is the one that will connect to the greddy unit if i can get them to connect the wire to the pin then i dont need to take the main unit apart i think.

i will take that route if i m unable to find a solution.

thnxx alot mate.

SUCCESS!!!

Thanks a lot @gtsboy your advice worked.i bought the white thing from jaycars and it pluged up straight to the main unit.hit 9 psi just in one run.

now i have some questions regarding tuning.

1-since i am auto should i tune it in 2nd or 3rd?

2-lets say my start boost is 8 psi and desired boost is 11 psi.DOES THAT MEAN IN A PROPER TUNE it will boost from 80 to 110?AND THERE SHOULD BE NO FALL IN THE BOOST WHEN ITS OPEN THROTTLE?

3-I am not sure what boost spike is i did only one run until 80 not sure in what gear but i saw the boost go up to 90 around 4500rpm but then it fell.IS THAT BOOST SPIKE?

thanks a lot in advance for all your help guys!!.

:yes: :yes: :yes: :yes: :yes: :yes:

Good stuff.

Tune in 2nd to start with. 3rd will have you going very fast whilst trying to see what's going on with boost. But after you've got it set up you shoudl check what it does in 3rd also. You might want to adjust it a bit.

With ref to your point 2....yes and yes. Although boost may still drop off at the top end. And that may especially happen if you're getting into R&R territory and there is just too mush fuel and too little ignition advance to keep the fires stoked. The Profec's gain setting is what you should use to try to stop the boost falling away at the top end.

With ref to your point 3....if your start boost is 8 and you're aiming for 11, then 9 is not a spike. If your setpoint was actually 8 at the time, then yes, 9 is a spike.

ya that what i was thinking if i try to tune it in 3rd gear it already goes up to 150 kmh in 5500 rpm.my car is boost 8 psi stock so i am gona tune it for 11.tomorrow i am driving to grampians so hopefully i will get it done there.

so basically spike is if it goes above my desired boost level.for eg i want 11 psi goes up to 12 at some point thats spike.

if boost goes to 11 around 5500 rpm but falls later on that means i need to adjust gain.

all good.

lets see what happens tomorrow.

couldnt wait until grampians. so went out to tullamarine just now.

i achieved 111 with

set 33

gain 33

set gain 70

the gain is too high but i could achieve constant boost throughout the rpm.

with this setting there was a slight drop like 109,108,then it was 110 and just before shifting to 3rd 111.will try to fine tune it tomrrow but is this good enuf?

if your target boost is 11psi you can probably bring up the set gain from 70 (7psi) to 90 or 95, bit closer to your desired boost level.

Or not.

The turbosmart eboost 2 recommends the set point (same as set gain on ptofec) yo be 5 psi less than setting.

But try it and see to be sure.

He's not using the turbosmart eboost. He's using the profec.....which recommends set gain a cpl of psi below target boost. Why would he follow the instructions of a different manufacturer for a completely different boost controller rather than that of the one he is using...?

Thanks for pointing out the thread title

I am aware of what he is using. I added that info so he is aware other manufacturers don't suggest setting the set point so close to the target as it can cause spiking.

Have you ever set up a profec? I have found if the set gain is too close it will spike, using a profec.

At the end of the day I don't care what he does, using it on a stock car is a waste of money.

ya setting set gain too close to wanted max boost gives boost spike.

i have it pretty much tuner actually i think its ok.

@superben.

man i just came back from grampians the roads are really nice and without any cameras so i tested out the car several times in stock boost and high boost.

i donno why u keep sayin putin the boost controller is a waste but 100-180 in 11 psi was really a lot alot faster then the stock boost.

i was actually selecting my mod list according to the HPI R34 VIDEO on youtube.

with a full turbo back exhaust system and 10psi boost they got 33kw gain on wheels.

i know i havent dynoed my car but even if i have 20 kw gain after the boost controller i dont think thats that bad.

What I was saying (badly) is that an electronic controller is a waste in your case . A cheap bleed valve would have achieved the same result for less cash.

Never the less,I'm glad it has made a decent improvement for you.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
