We have support for the 1B9, explicitly - UMA 7/16-20 UNJF Oil Temp (1B9) - is what it's called in SkyView. It looks like, from the datasheet ( http://www.umainstruments.com/pdf/spec1BxRevG.NON-TSO.pdf), that all of the 1BX sensors are the same electrically. So that's a tentative "we think so". Note that if it's an engine on an LSA, you'll need approval from Rotax / the LSA manufacturer to make any mods like this.
