Thread: A few question setting up 2JZGTE JDM Aristo and MAP ECU

  1. Default

    Do you know what the 3522 corresponds for injector duty cycle?

  2. Default

    Any idea? Also I posted in another thread but I THINK the way to get around this is to raise the base fuel pressure and then scale the map down accordingly?

  3. #13


    Sorry, there is no real answer because it depends on the OEM ECU fuel table. It will be different based on load and RPM. As per the other thread, you are correct. Increasing fuel pressure is a way of getting more fuel from a given size injector without installing a bigger injector. It only works to a certain level as the injector can only flow so much regardless of pressure.
