Hmmm another thread hijack haha lol, well quick update, going in again on Wednesday, got all the fuel out, ran some fuel with injector cleaner just to clean things up a little, tomorrow hopefully going to drop in a set of new spark plugs BCPR7ES-11, new fuel filter and a quick Liqui Moly De-Carb, a fresh tank of BP 98 and see how that goes, hopefully with the fresh fuel with no additives and a colder plug the NOX should lower and pass, will let use know how I go, thanks.

NOX level too high again, this time it was 1.30 max it's allowed is .63, from everywhere I've read is high combustion temperature/car running too lean.

So tomorrow I'm gonna make a pipe to sit where the air flow meter sits and pump it up with 20psi of air and check for a air leak, thats all I can really think of it being, and also check my fuel pressure incase my fuel pump is pooping itself causing it to lean out, and far out with Australian restrictions lol, I wish I was in America right now because CRC has a product called G2P (Guaranteed to pass) that you put in you're fuel and somehow it just kills all of the levels for a emissions test lol.

As far as the THX and Co2 is concerned its way below the allowable limit, THX is .20 and CO2 is 0.02 this time, gotta wait till next Wednesday again ffs.

That sucks so bad! I read somewhere ages ago that retarding timing and raising idle and adding fuel pressure will help reduce NoX.... Not 100% sure though.

Good luck next time!

In that case would you like to contribute to my Bigger Turbo fund :-D haha lol, yeah man trust me you don't want to be in this position it sucks, plus its my daily, and now the car I have been driving is just too low and the seating is low aswell so its not doing me any favors to my stuffed knee, pain from everywhere haha lol.

Well today was my 6th attempt and still no good, this time the THC was 0.39 Nox was 1.19 and CO was 2.5, there was a silvery/green r34 infront of mine and he passed on his 4th go, my dad took the car today as I couldn't make it, and he didn't get me his number, if anyone knows him or if you're reading this could you please please please inbox me asap, my rego is getting cancelled on Friday ffs, I'm so sick of this, its been 8 weeks now, this time I put in a mixture of vortex 98 and E85 making it E30 and still nothing, the testing guy apparently told my old man "this cars being used as a racing car or something?" wtf was that meant to mean, thanks.

    • 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
