Tracy, I’m presently flying without an EM2, using steam gauges. But the more we fly and try to monitor various pressures and temperatures I can see the value of having an EM3. I guess the purpose of the EMx is to replace existing steam gauges.

How compatible is the EM3 (or my existing instruments) to paralleling of existing sensors?

Would I require some buffering circuitry (op-amp/voltage follower) for isolation? … or duplication of sensors?

It's way late but I finally got the documentation, production, etc  sorted out on the EM3.

  It has all the same features as the EM2 plus 4 additional CHT and EGT inputs which can be used for general purpose temp measuring channels.   Also it can do data logging on every input at 1 second intervals.  Data stored on a USB 'thumb drive'.   Log is displayed using an EXCEL spreadsheet on PC for analysis.

It is also modular so you don't have to pay for features you don't need.   Price is lower too.  I had them made in larger quantity to get lower production costs.

Went back to the two part architecture (Display and acquisition module (AQM) of the early EM2 because of the fewer wires needed between the panel and engine room (total of 5 wires).  This makes the connections between the AQM and engine sensors much shorter.  If the temperature guidelines are followed, the AQM can be mounted in the engine bay.   The new design eliminates the noise problems which limited the distance between AQM and display seen on some EM2 Canard installations.   I,ve tested to 30+ feet and even more should be possible.

Not ready yet but soon will have an option for Altitude Encoder output for connection to your  transponder. 

At the risk of encouraging more feature creap, are there any other functions you guys would like to see in an engine monitor?
