Since I've got the attention of another metric guy down under, I'll throw
this out there.
Has anybody attempted re-scaling the EM2 to display in metric? Last summer
when I added a set of SW resistive fuel senders to my auxiliary tanks to
make use of the EM2 fuel input, as I was calibrating these data points I
decided to have a go at changing the zero & span (scale factor & offset) to
read in liters. It was easy and worked well.
   I was 10 years old when Canada made the switch to metric so I'm quite
comfortable in both systems of measurement and can easily visualize each
unit without converting in my mind with one exception... temperature. Water
freezes at 0C and boils at 100C, pretty simple and it's what I'm most
comfortable with.
  So I don't really care about the fuel level & press, speed, alt, etc. But
I'd really love to convert all my temps to Celsius. For many of the sensors
this should be almost as easy as it was for the fuel level, but it doesn't
seem possible to calibrate any of the J or K TC's. This would be quite
undesirable to have two different temperature units.
 The other unknown is what calculated parameters would be affected by a
change of units?
Would this affect autotune?
Or am I just going to have to get used to Fahrenheit?
