Also: I could calibrate mine quickly against the
SG and then pass the settings on to anyone else with a mk4/5 car.
What would be the difference between avg MPG and Trip 1/2?
Another good parameter the MID has: % engine on vs. engine off by distance.
What else does it have, Ben?
The ability to view FE in different measurements would be good too. It's one of the things that held back the SMID's popularity on this side of the pond. L/100 km, km/L, mpg (US), mpg (Imp).
