Hi Doug,
Trying to connect the single temperature sensor to two instruments
isn't likely to work. There are several different types of devices used
for measuring temperature. The EM2 is supplying 5V to the EM2 sensor,
and you don't want to be connecting voltage sources from two different
instruments together. I have no idea what the RMI is using but
connecting them together isn't a good idea.
You can still use the EM2 sensor to measure whatever you like. Just
remember that the OAT reading on the EM2 is something else and read OAT
only on the RMI.
The EC2 temperature sensor must be used to measure the air intake for
the combustion air as that temperature affects your mixture.

I have a Rocky Mountain Instruments Uencoder in my panel and already have an OAT temperature sender associated with that; so I was wondering if I could just run a "Y" from that shielded wire when it gets to my panel with one lead going to the RMI and the other to my EM2 for OAT display. My possible concern would be if this might cause some unacceptable errors in the temperature measurement. If is feasible to do this it would allow me to use the OAT sensor that came with the EM2 for other tasks such as sampling the air temp coming out of the radiators, etc. Doug Lomheim
