Saturated injectors are used in almost all-standard production, 1998, engines because of the system cost and simplicity. Saturated based systems usually fire all injectors at the same time, once every rotation discharging half of the required fuel per cycle at each event. Some systems fire half of the injectors at one time and the other half at a different time. These systems are called "Batch Fire" and "Semi-Batch Fire " respectively. This system is used in 90 % of all general production engines (cost and simplicity). In almost every case Manufactures will only use Peak and hold injectors in High Performance applications or in Turbo applications. This is true in the Ford/Mazda family, Chrysler/Mitsubishi family, Nissan Group and the Honda/Acura folks as of 1997. General Motors/Toyota cars are also in this same family. OEM APPLICATIONS GM uses Saturated Rochester injectors in everything but some of the High performance cars, hear they use Lucas Injectors, and in the turbo trucks they use Bosch. Toyota uses saturated injectors in everything but its turbo models - all Nippon-Denso. Honda, last year changed all but the NSX to saturated, most all of Keihin make with some IPT. Nissan uses saturated units only, as of this year, Jecs or Hitachi manufactures. Chrysler/Mitsubishi - same deal - all but the turbos are saturated, Siemens or Bendix make. Ford uses Bosch or Nippon-Denso depending on the Model. All are Sat. except Turbo Models. Bosch and Lucas injectors are used in VWs.. BMW , Bosch up until this year, now Lucas --- European cars use an assortment of injectors

    • 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 ? 
    • 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).
