    Hello there.
    Have a 2012 Stelvio, Factory Roller, with twin lambda probes.
    Have read somewhere that Guzzi original probes are a cheap type and lack range.
    If that is so is there any benefit in changing to better quality probes, with better range?
    If so; any recommendations?
    Yes I know that a change in mapping would be a better approach but not confident to do myself and being down here In Tassie no ready access to Guzzi gurus on the mainland who would be able to do that work for me.
    Appreciate your comments

    No, none at all. The ECU uses them as a simple switch, as the ECU is not adaptive. Best to put your money and energy towards this; https://gtmotocycles.com/products/gt-motocycles-5am-7sm-reflash-tool -- you can read the reviews there.
