Altitude. In understand that the altitude readout isn't adjusted for current pressure, but still. Mine reads 687 ft when I'm actually at 14 ft. Is there a way to adjust it so that it's al least close? 
 
I'm guessing Tracy's altimeter setting is fixed at 29.92, so I would expect the EM-2 to agree with an altimeter with that standard setting as well.  I'm afraid I haven't tried it though, and I don't recall how close mine is.  I agree with Al though, every cal needs to be checked, including the alt I guess.   
 
Warnings. The system sends an intermittent ground to flash a warning light. If you're using a voice system or a LED that flashes anyway you'll need a steady ground. So, instead of saying "John, Check the engine monitor" my voice system says "John...John...John..." 
 
Can you change the message?  If so, can you just change it to "engine" for now.  Seems like that would be functional.   Once you get full message capability, perhaps I can record some messages for you :-)
 
I also notice that the offending item on the display flashes about once every 30 seconds. I find that this is too long. If you miss the first flash you have 30 seconds to wait until you know what's wrong. I'd rather see this flash set at every 3 seconds or so. 
 
I recall mine flashing way faster than 30 seconds.  Perhaps Tracy changed the software.  I wonder if there are any two EC-2's or EM-2's that have the exact same code :-)
