Hi Bill,

Unfortunately there is not a simple yes or no answer to the sensor=20 connection question. Voltage output sensors like the OAT, AUX 1 = & 2=20 air temp sensors and CHT / EGT can be hooked to several = systems=20 at the same time but variable resistance sensors like the water & = oil temp=20 & pressure sensors can not. The EM2 fuel level inputs = were=20 designed to be used in parallel with Van's Aircraft fuel tank = gauges.

The EM2 can measure tach speed in two ways. The default = scheme is to=20 look at the rep rate of the fuel injector pulses. This could be = used by=20 multiple systems. The other method is to use the serial engine = data from=20 the EC2 and calculate RPM from one of the parameters in that data.

Greg at Blue Mountain had requested the EC2 protocol (I sent it)=20 and was going to build in an interface to the EC2. I doubt = that he=20 has had time to do that though. There is only a tiny number of his = customers that would use this.

Yes, you have the switch type for the coil disable switch = correct.

Hi Tracy,

EM-2 and upgraded EC-2 arrived = Saturday.=20 Thanks,

A question:

I am installing the Blue Mountain = EFIS-1 in=20 addition to the EM-2. The BMA will allow logging of some of the engine = parameters for later analysis.

I believe you are planning on a = BMA/EM-2 combo in=20 your RV-8 also. It is my understanding that I cannot hook a = temperature or=20 pressure probe to both units, is that correct? What about Tachometer=20 connections?

EC-2 question: I apparently lost the = coil disable=20 switch supplied with the EC-2 back in 01 when I originally received = it. I=20 interpret the drawings/schematics as the switch being a (on)-off-(on) = switch=20 (springloaded to center off position, with momentary on positions both = ways).=20 Just want to verify that before I order a matching switch to my=20 others.
