Tracy, I’m presently flying without an EM2, using stea= m 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 t= he EMx is to replace existing steam gauges.

How compatible is the EM3 (or my existing instruments) to pa= ralleling 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 fin= ally got the documentation, production, etc  sorted out on the EM3.

  It has all the same features as the EM2 plus 4 additional CHT and EG= T inputs which can be used for general purpose temp measuring channels.   Also it can do data logging on every input at 1 secon= d intervals.  Data stored on a USB 'thumb drive'.   Log is displaye= d 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. &n= bsp; 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 engin= e room (total of 5 wires).  This makes the connections between the AQM a= nd engine sensors much shorter.  If the temperature guidelines are follow= ed, the AQM can be mounted in the engine bay.   The new design elimin= ates 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.
