R32 Gtst Missing - New Problem

Hi,

R32 GTS4(t) I have been having this problem for a short while now. After driving for a while (usually quite hard or in warmer weather) my car develops a mis-type problem. At say 3000 rpm in fourth gear (a little low I know), I will but my foot down on the accelerator and nothing will happen - the car kind of splurts about but no power. It feels a little like when you blow an intercooler hose. After a few moments the car will return to normal and after a few longer moments begin to splurt again. If I turn the car off (say at the lights) and start it back up again it seems to work OK.

I have a boost and fuel pressure guage which both read pretty normally when this happens so I don't think it is a fuel pump / wiring / delivery issue.

I noticed today (which I have not noticed before) that my exhaust temp warning light came on? Does that help?

I had a quick search around and it seems that no-one has described anything like this.

I need help!

Are you using the factory IC? It's possible you are getting detonation because the air temp is way too high, and the knock sensors are retarding the system.

The factory IC, when used in Oz on a hot day, is about as useful as tits on a bull.

      TPS voltage RB25DET

      By BASHERnissan · Posted

      Hi guys my TPS voltage is reading over 2v at idle.  My Haltech ECU is reading around 40% throttle position at idle also which is really strange. Note the actual throttle position sensor is brand new…    anyone have any experience with this or know how to calibrate it on Haltech ?

      Cas issue

      By joshuaho96 · Posted

      The OEM disk will not work on any AEM ECU, you need to use the one they made. You shouldn't have to flip the CAS or whatever you were describing, if you set the ignition sync offset correctly it can't backfire. Make sure you're using a spark plug lead on coil 1 instead of the timing loop to avoid weird issues with the timing light. Double check that your timing settings are actually correct, like is the 24 tooth configured correct or should it actually be 12 teeth for 1 crank revolution? I also found this: 305817248-AEM-Undocumented-Settings-v1-2.pdf

      Yeah, I don't believe the M35 uses a deadhead system.

      Have you done your thinking backwards? 3 bar, 43.5 psi pressure drop being the presumed specification for an injector, means you need 3 bar upstream when they are firing into atmospheric pressure, and more upstream pressure than that when on boost (you add your boost to your rail pressure to maintain 3 bar across the injector) and you need..... less pressure upstream when you have vacuum in the manifold. So, presuming that you're idling at -10 psi, then you only need ~23 psi in the rail. I realise that I did not need to say all of that to you specifically Matt, once you'd realised your mistake. It's mostly there for complete clarity for others.

      Have you reached out to the guys at Spool Imports? They are a Ross dealer, I can imagine they would have the rings just sitting on the shelf (I could be wrong).
