LOW_INJECTOR_SLOPE

26.0995

  • #

    Injector slope lb./hr

This parameters compensates for the physical limitations of a particular fuel injector for unusually small pulsewidths (<~4ms). In general, real life fuel injectors are sloppy when the commanded pulsewidth is close to the duration of the opening and closing event time for the injector solenoid. Typical injectors take about 1 ms to open and 1 ms to close. That is a total open/close event duration of 2 ms. When the command pulsewidth is in this low-pulsewidth range (<~4 ms), the real-life fuel delivery is not linear to the rated full flow injector delivery rate. The LOW_INJECTOR_SLOPE is a fudge-factor that accounts for this deviation.

Injector pulsewidths are lowest when the RPM is high, and the throttle is closed. Idle pulsewidths are in the 2-4ms range. Larger injectors decrease all pulsewidths in direct proportion to the size increase. Double the injector size, halve the pulsewidths for any given airflow.
