mrk - thanks for the manual.
It does appear as if it does not measure instant mpg.
It should arrive Friday. Do not own a SG so am not familiar with SG functions. I will mess with this new TP100 thing and try to figure out what it will do.
The USB interface caught my eye too. Will be interesting to see what you can do with it.
So please ask about anything you can think of (pertaining to this guage
)
And, teleman, my heat is both hotter AND dryer than yours
