pfc boost control kit install

[Kinell]

Anybody got an idiots guide on how to install a pfc boost kit on a gtr

[GunMetalR33]

I would like the same info...

So far this is what i know:

1) Connect the Apexi map sensor (included in kit), if you have an r33 find the sensor that runs the stock boost gauge then run a T peice of the hose that connects to it. Then run the hose to the Apexi map sensor. If you dont have an r33 then use the hose that you run your boost guage off. Next you need to connect the apexi map sensor to your PFC (cable included and there is only one in the kit that will fit).

2) Connect the apexi boost solenoid, simply replace the stock solenoid with the apexi one. NOTE, you may have to change the posi of the ports on the solenoid depending on you setup. (see the guide on the US apexi site for the AVCR). You plug the apexi solenoid into the plug that the stock solenoid used. If the plugs are not the same it probably means that you have a solenoid for the GTR and you might have to cut the wires and solder them.

3) Tuning, go to the boost menu on the hand controller. Set the desired boost level in BAR. Go for a run under good load in third gear. If you do not get the boost you wanted then increase the base duty, if you over boosted then retard the base duty. NOTE: If you increase the base duty too much then your boost controller will spike, but if you dont have enough base duty then you wont come on boost hard enough. You dont have to get it exactly right though as the boost controller will learn the right boost curve after a couple on runs.

I am in the process of doing the above and I hope it all makes sense. If you have any further questions about the install then send me a PM. Chances are that I would have had the same problem.

Thanks for the info gun. Does the pressure sensor tap into the intake plenum? & if so, at which point

[GunMetalR33]

Yes, it does go tap into the intake plenum. There should be some hosing about 5 mil think comming of you plenum for your boost gauge to run off.

what model is your car? does it have a boost gauge?

[Kinell]

R33 GTR, no boost guage. I will have a look this afternoon & see if there is somewhere i can hook upto Thanks

[GunMetalR33]

So does the r33 GTR have a stock boost guage? If so it will have a small 1 bar map sensor at the top left of the engine bay. You can tap into the hose running of that.

[Kinell]

Yes i have stock boost guage i will look this afternoon & let you know how i go.

Thanks for your help Gun much appreciated.

Or you could tap into the fuel pressure regulator at the front of the plenum. (this is where the Profec B picks up the pressure from)

[GunMetalR33]

Yea, my boost gauge is tapped into the fuel pressure regulator...

[Kinell]

Yeah found the pressure regulator, underneath the the intake plenum bitch to get at

though

does anybody know how to wire one of these kits into an r32 rb20det, i need some help kinda confused, heard sumthing about runing new wires but am unsure what for?
