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.

  • 3 weeks later...

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.

    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂  
    • Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
    • It's TWO steering wheels actually. 😛 one for each hand They are wheels, and they steer!
