Hi George,
 
Here is what the EFISM looks like = in its=20 case.   This is the main flight screen with Air/Fuel = Ratio=20 indicator (top), Fuel Flow and Fuel used.  There are a number = of=20 other screens some of which shows the RWS EC2 fuel maps and = ignition=20 timing.  Check out www.andersonee.com if = interested in=20 more information.
 
But, to answer your question, the = EFISM=20 gets all its fuel flow and usage information from reading the = injector's=20 pulse train (no sensor required).  The Air/Fuel Ratio = indicator uses=20 the O2 sensor (narrow band) and if you want to see the Ec2 fuel = maps and=20 manipulate them using the EFISM then it requires 2 wires to the = data=20 output of the EC2.
 
So the O2 sensor is really the = only sensor=20 needed.  Tracy Crook offers the EM2 which is an aircraft = performance=20 and engine performance unit offering much more capability than my=20 unit.  My unit would primarily be of interest to folks who = say -=20 already had an engine monitoring unit (Such as a Grand Rapids of = others)=20 but wanted to also add this Fuel monitoring/management system and = did not=20 need/want to duplicate the functions provided by the = EM2.
 
 
It occupies the standard 2 1/4" = dia=20 instrument hold - is 1 1/2" deep and weighs 2 1/4 = ozs.
