Huge thanks to the developers for adding the features I’ve requested not too long ago. 
Report back:
Engine temp seems to be working. 
Fuel range - not working. I’ve found out the R NineT’s only got a reserve switch in the tank, no float or fuel strip, so the tank is always full, or in reserve. Thus the display keeps counting up showing 400+ km range. 
Alternate range in reserve - this seems to be working great! As soon as it hit reserve it started counting down, rather than up from 0 like it used to. Will test some more, but this should be a very useful feature. 
Shift light - haven’t had a chance to test yet. 
Thanks again.
