    Curious how that ties into the offset though.

    The PCM determines the PW it would require based on air/fuel model.

    Lets say 1.5 ms.

    Then would reference the voltage offset table and the map offset.

    Yet for the OSID with a min PW of ~1 the offsets are the same as the min PW of ~0.65 OSID.

    This is comparing a 1999 GTP to a 2002 GTP.

    Result would still be ~1.99 ms in both cases.

    My understanding of min PW is that it acts as a minimum PW the PCM can command before fuel trims to prevent attempting to run the injector at a rate at which it can not operate reliably and relatively predictably.

    I can see how this would be very useful for overly large or injectors accurate to much lower pulse widths.
