Hey guys,

Just got my baby in from Japan, 93 r33 GTS-t =D Going to normal maintenance befor I take it out for the summer. After a few test runs i got my boost up a bit with out going pass the 12 PSI limit of my ceramic turbine. I had this weird thing happen at 0.80 Bar . My english is not to good so i dont know how to explain this but at 5500RPM the car seems to hit a fuel cut, feels like a speed limitor but i get kind of a rev cut from the engine. Here is my setup and what i know from this car ;

- Sard Boost controler

- what seems to be a piggy back ECU on my passenger floor

- After cat exhaust

- Got some new plugs gapped at .8 and a fresh oil change and filter

Only thing I can see is my 94 octane Canadian gas :\ Could this be solved with a simple SAFC and a good tune ?! Or should i check my ignition ?

Thanks for any info :D

      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

      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).
