Builder Tip #129 from HomebuiltHELP 
Engine Monitoring Systems: are they all the Same?
Learn the differences before you buy!
An EMS (engine monitoring system) is a popular and important part of your homebuilt's avionics panel. Many builders are opting for electronic displays rather than the steam gauge analog variety.

When it comes to engine monitoring , picking the right product has a lot to do with the challenging wiring process of connecting engine sensors to the display. Every engine installation uses a slightly different combination of sensors . Have you thought about the process required to wire each sensor to the EMS display? It is the method of connecting these sensors that can be unique to each brand of EMS.

If you are planning on installing an EMS in your homebuilt aircraft, understand the effort and components that are required for the specific display that you have chosen. This video explains one such difference in wiring methods between two popular brands of EMS displays!
