Example Engine Sensor and Transducer Installations
This section contains example engine sensor and transducer installations for popular engines.
Each engine subsection listed on the following pages contains tables for each SV-EMS-220/221
connector and suggests a way to connect that engine’s required sensors to the EMS module.
These tables are based on the downloadable mapping and settings files available from Dynon’s
support forums and may need to be modified based on your particular installation.
