u mean a new air flow meter?

Yes I think he means AFM... MAF stands for mass air flow..

The voltage output of the AFM is a bit larger than the range of 0-5v...

The ECU sees its maximum as 5.12v because this is the highest voltage the A-D converter in the ECU can output. I would expect the afm output to be say 0-6v or 0-7v or something like that..

This is probably irrelevant though because if you are getting 8.2v at the signal when there is no air flow, the afm is indeed toast...With no air flow it should be at least under 1v.

      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).
