Bet it won't work with 2T. Probably clog the sensor.
However please ask them  :)

I know that some guys use it in the "Vespa-Scene". Most sensors don't like the 2 stroke oil though and die after some runs.

Other problem is, that I don't think a perfect combustion (stoichiometry wise) is always good for an engine. You could detect way too lean and way too rich conditions, with fine tuning tuning I'm not sure if it's optimal.

But that's just my two cents.

Those are great tools for 4-strokes carb tuning. Heard that the O2 sensors would not last long on 2-strokes but long enough to be used for measurements.

Never seen or heard of a more highly recommended real world AC/LC Yamaha tuner than Dave - https://www.muttsnuts2strokes.co.uk/
