This thing is awesome in my 2 stroke kitfox. If you have more than 2 cylinders you’ll need to add the RDAC. Mine did come with an OAT probe. I was replacing steam gauges so already had all of the sensors installed and was able to unplug them from the old instruments and wire them to the harness of the Ems-2. I’m displaying volts, rpm, water temp, OAT, and egts. Very straightforward installation and even easier if you get the RDAC.

I haven’t used it yet but if you have an engine with more than two cylinders you will need their RDAC, another $200…. So far MGL has been fairly responsive answering questions about how to hook everything up. I. Running a superior O360
