IF you have a boost controller then it doesn't matter what it does. It is for the factory boost controller, it keeps boost to 5-6 psi when the car is under 4500rpm once it revs past this it lets it boost to 8psi. If you don't have a boost controller then reconnect it because you only be getting 5-6psi through whole rev range.

But by the looks of it you have a boost controller in so reconnecting it won't do anything.

I dont have a boost controller and the standard one is unplugged at the moment, plugged it back in and it didnt seem to be any different but I didnt rev very high 4000-5000 maybe.

Can I bypass it al together and run a hose straight from the intake pipe to the actualtor and get full boost all the time??

*UPDATE*

At first I was told that the solonoid gave the car low boost in 1st and 2nd gear then full boost in top cause mine is auto.

But it seems that the guys on here are right and I plugged it in again took it up over 4500 and can definantly feel the difference in power and the boost is a bit higher on the gauge also, dunno why the previous owner would have pulled it off(He simply unplugged it).

Now it pulls great up top and even better when the Profect B goes on soon .

Thanks again for the link and help guys!!

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
