On mine, the vacuum hose is connected to the rear of the plenum, there is an unused fittingthere that is the right size. The vacuum hose then goes out of the engine bay to the RHS guard, accross the rubber door seal and up the A pillar where the boost guage is located in a POD.

:starwars: cheers :)

So... If I want to use that one for my guage, can I remove the stock connection and use the nipple? That pipe on the Skylines just goes to the ECU somehow, right? It's not going directly to the guage on the dash? Cheers!

There is an unused nipple at the back of the plenum, take the rubber cap off it, connect the vac hose to it.

Run the vac hose past the firewall somehow, i used the big gromment next to the ABS, then run the vac hose to the guage.

Mount where desired, enjoy the b00st :D

It certainly doesn't go to the gauge in my R34 skyline (or S2 stagea) as the ECU knows the boost (which is why it comes up on my laptop as well as the central gauge..) and goes to the gauge in a wire :-)

Thanks, Ian! A mate told me the same thing, but I'm curious as to why I don't see any boost reading in any consult software that I try. I would also like to use that pipe to go directly to a boost guage that i'm fitting, rather than tap off something else.

The only real pipe I can see goes to the MAP sensor, I think. (it's tiny)

Most of the consult software out there is crap, written in VB by amateurs.. :P Mine will be out in a month or so (pm me your real email address and I'll send you a copy to test if you'd like) and includes everything you can get out of the port, not to mention real time graphing and 'replay' ability etc.. Written all in C++ :)

The only reason I've written it is that I've seen how bad the ones out there are...

And I guarantee the turbo boost IS coming out of my R34 consult port, as I have had it up on my screen many times while I've been testing my software!

:(

Hi Ian, there is no MAP sensor on my Stagea S1, the ECU has no way of knowing the boost level. I will be very interested in having a look at your Consult software when it is available.

;) cheers :spank:

Ah! Thanks Ian and SK! That answers my question. The unused nozzle on the back of the manifold on a Stagea is what the Skyline uses to go to the MAP sensor.

Ian, PM sent... i'd love to monitor my boost digitally! =-]

ie includes the turbo boost, and a stack of other things that we don't know what they are (I'm hoping one is front/rear torque split :P

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
