    what does OL - Not Ready mean? Better yet, what is the list of conditions and what

    Hi,

    I am busy calibrating a vehicles VE tables.
    I have noticed that while scanning I see Fuel System #1 status = OL - Not Ready.
    what does that mean?

    Does this mean I am not in Open loop?
    Do I ignore and continue?

    (find this hard to believe since STFT and LTFT are all zero and the front o2s are removed from the vehicle)

    I am calibrating adjusting VE to match FA.
    Thanks

    OL not ready means you're in open loop.

    Thanks Russ.
    Guess I was expecting "ready" or something other than "Not Ready".
    I wasn't experiencing any issues logging or calibrating but had noticed 'not ready' and thought, 'so it is not in OL?' (something affecting this).

    What's not ready is closed loop. Therefore you're in open loop until the conditions for entering closed loop are met.
