Thread: Injector Off Time = Injector Dead Time

  1. #1

    Default Injector Off Time = Injector Dead Time

    Guys. Just as the title states. Is the field in the software that is labeled "Injector Off Time" looking to the dead time of the injector or something else?
    I'm running Siemens Deka 80 lb/hr high impedance injectors and have the offset data for them. I just want to make sure this is what this field is looking for.
    This is what I have calculated for the table based on the offset data provided by Siemens.
    Now assuming this table refers to offset, I can double check my numbers by watching the AFR (without
    any modifiers) at a specific voltage, and look for erratic AFR readings and adjust from there correct?

    How did it go with this data? Asking because I'm about to go down the same road.
