    Injector Duty Cycle Reporting with 16197427 PCM

    I am using the $0D bin. It appears that the my XDF computes the Injector Duty Cycle via the injector Base Pulse Width and Tachometer readings.

    The conversion in TunerPro is this:

    X * Y / 60000 * 100

    where X is the Injector BPW and Y is the Tachometer input.

    But why the 60,000 * 100?? Isn't that the same as 6,000,000?

    The reason I'm interested in this is because at WOT, my fuel tables are as close to 100 as possible but my injector duty cycle is reporting at most, 30 %.

    I'm wondering if I'm not understanding something right (quite likely) or of there is some other parameter that I'm not seeing. Thanks!
