Guys,

could anyone with the Apexi boost controller than is run with the PowerFC please post some pictures of how the solinoid is plumbed in. Cant get any more than .96 bar cboost which i think is the actuators controling that level of boost.

regards

You need to plumb it in wherer the original solenoid was, and then make sure the wiring is setup corrcectly.

The original wiring went to the original Nissan ECU, so the Power FC makes use of these already existing pins/wires so you need to have the solenoid tapped in to the original wires so it can use those channels to control the solenoid

So original wires need to be used from old control valve.

I thought the new control soliniod had its own wiring that was supplied with the kit, this loom was then pluged in with the MAP sensor into the power FC as shown in pauls DIY

the Map sensor pretty much was, detatch the original sensor, palce the new one in the same position,

Plug n play, easy, used the same boost feed hole too odff the plenum.

feeding the wires thru the firewall to reach the ECU was the hardest part as they don't leave much length to reach.

I put the new solenoid in the old solenoid postion (R33 GTST)....

The male plug you have going into the solenoid i chopped and soldered onto the old wires that fed the old solenoid...of course chopped to and soldered together to make a new fitting.

So now i can still unplug the solenoid if for some reason i need to.

(So i think there was a whole length of wire unused, long time ago now but it should still be boxed somewhere)

I've just taken a photo on my phone/camera which doesn't show it too well but it may help.

I'm at work again... so i can't access the home PC

Don't suppose you are in Sydney anywhere?

PM, coming too

LOL nope try Dubai which aint just next door either.

Looks like the only difference is that you used the old original wiring and i did as per the pic above.

Note looks like i might have had the Com and NO ports on the solinoid arse about, not sure what diff that will make but test tomorrow night.

OK, just dit the pics

You can see where the black electrical tape is, that's where i cut and soldered back to the original male/female plug.

The reason i kept the original plugs and not the new plugs (which you can do, just cut on the other side of the plugs) is that the original Nissan plugs are mage for the metal bracket so might aswell use that to keep it nice and secure.

Might be different for your GTR but see if it helps

Looks like NC gets the pressure feed from the intercooler piping....and...

COM continues the pressure feed to the wastgate.

      Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed

      hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me

      Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
