Apexi Boost Controler

[tacker]

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

Guys,

its it just a matter of replacing the stock control valve with the apexi unit ? If so it aint working on mine.

Check PaulR33's tutorial mate, everything you need is in there

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.
