    Question L67 3800 SII - Injector Duty Cycle % Scanning

    I have a 1999 Riviera and I am seemingly unable to get the injector duty cycle % PID working in the scanner. Everything else works fine except this one.

    What am I doing wrong?

    Can you post your scanner with what you got going?

    The formula I made for IDC %:
    Engine RPM * Injector PW / 122
    [PID.12]*[SENS.112]/122


    It doesnt do anything.

    I can see Injector pulse width values in the scanner tool but my custom IDC PID doesnt do anything

    I made one for boost and it works great
