APPENDIX H: Eagle EMS Interface
The engine monitor can be configured to display engine data from an
Eagle EMS Electronic Ignition. The Eagle EMS and AFS Engine Monitor
share CHT, RPM, Fuel Flow, Fuel Pressure, and Manifold Pressure.
Below is the method of getting the data from the EagleEMS to your AFS Engine Monitor.
CHT - EagleEMS recommends a splitter made by JPI
RPM - Install a 1K ohm resistor between the RPM output of the EagleEMS (wired to Pin 32 of the
AFS Engine Monitor) and Pin 31 of the AFS Engine Monitor
Fuel Flow - Install a 1K ohm resistor between the Fuel Flow output of the EagleEMS (wired to Pin 14
of the AFS Engine Monitor) and Pin 15 of the AFS Engine Monitor. Set K-Factor to 330
Fuel Pressure - Install the fuel transducer for the AFS Engine Monitor in the standard location (on
the 3-port manifold provided by Van's). EagleEMS gets fuel pressure from a different location on
the engine.
Manifold Pressure - 'T' into the manifold pressure hose coming out of the engine fitting going to
the EagleEMS.
