    Depends on the LPG system dunnit.
    Vapour injection usually yes, old style converter ring usually no.
    You would help by specifying the brand and model of yours , but then I couldn't help, but some LPG expert on here could.

    If it is installed then it is easy to check.

    If it is a mixer system then there will be a gas hose going between the factory air intake and a gas component. In that hose there will be a tap. If the tap has wires coming off it then you are using oxygen sensors if not then no oxygen sensors.

    If it is an LPG injection system then it uses oxygen sensors.

    Hmmm
    I have a oxygen sensor and its not vapour injection.

    Just depends on the system and installer.
    The computer needs certain info and my last 3 installs actually all had them.
    May just be the technician than.

    Runs a treat and have no complaints.

    Agree with bigguy.

    Vapour systems generally don't have a computer so nothing to hook the O2 sensor too.

    Injected systems can be set up a number of ways. The O2 can be fed to the computer to adjust mixture while car is running and to help with the initial tune or if no O2 the installer can manually adjust the mixture for different revs when tuning the gas. Most installers like O2 as it makes their job easier but the car can be tuned effectively without one (my car doesn't have one but is injected).

    Cheers,
    Remy
