Ive just recently checked vaccum lines AGAIN, cleaned my afm, aac valve on my rb25det neo thinking that will solve my low rev hunting issue but still hasn't changed my problem. I followed the tutorial on how to clean the aac value, followed mostly everything on the tutorial but when it came to the adjustment on the idle i realised the the tps on the neo's are different? From here i became puzzled so if anyone has any information on this topic im all ears.

My neo's completely standard only has a tap on it.

Any help will be good. Thanks.

Hey mate, not too sure what you mean by low revving issue? As you saying you cannot rev high or are you saying at low revs something is acting up for example it's idling rough?

Before you do anything, check turbo gasket, exhaust piping, hoses connecting air cleaner and blowoff valve if you have one. 

Then let us know further.

When the car is at a stand still the revs are abnormally low, when you put your foot on the accelerator and then take it off suddenly the revs drop really low, at some points almost causing it to cut out. Even when its just turned on and hasnt warmed up the revs are low. Thanks for your help!

I think the turbo gasket is broken or come off and check air filter clamps and hosing.

Also check check and clean out Throttle body plate and air intake valve. Dirt deposit sometimes builds up in these areas over time. Just remove and clean with some grease remover and soft cloth. Or you can buy an air can and spray.

    • 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
