Todd, did you ever get the EM2 recalibrated to metric? I never attemped this as doing so usually gives me quite a few hours work to get back to a working system. I used Tracy’s factory calibration in the EM2 as the base to calibrate my efis, which is in metric. It is a minor inconvienience to do the mental arithmetric when comparing instruments, but would be interesting to know if you succeeded.
