Now, you should see the list of ECU 
parameters that can be displayed on the 
Dashboard, as well as the other Seagull 
Parameters. Select the desired 
parameters and configure alarms on the 
new ECU parameters as described in your 
Seagull Pro Flight System manual. 
 
Here is specific information about the 
ECU parameters: 
 
ECU Throttle % - this indicates the 
throttle deflection percentage 
ECU Turbine Temperature – this 
indicates the turbine temperature. Note 
that it is ALWAYS in Degrees C on the 
Dashboard, even if English units are 
selected in the application 
ECU Turbine RPM – this indicates the 
turbine RPM. IMPORTANT: please 
make sure that you place the RPM display 
on either the left upper or left lower 
display location (not on the right side of 
the screen). This is because RPM can go 
about 99,999, which means it won’t 
display properly on the right side. 
ECU Status – this page on the Dashboard 
indicates the status of the ECU. The messages vary depending on which ECU you have, and should be similar to the 
messages your Data Terminal/GSU currently displays. When no ECU is detected, “ECU NOT DETECTED” is displayed 
on the ECU status page of the dashboard. 
ECU Pack Voltage – this indicates the voltage of the ECU’s main power supply. 
ECU Pump Voltage – this indicates the current pump voltage. NOTE: on the FADEC, this indicates the pump duty 
cycle. 
 
Live Mode Application Display
 
All of the ECU parameters can be displayed in application Live Mode, when either the Dashboard or the Recorder is 
connected to your PC/Laptop via USB. To configure the parameters to display in Live Mode, click “Tools, Choose 
Instruments to Display on PC Screen” and the ECU options should appear on the righthand side of this page. 
 
Range Checking and Flying 
 
IMPORTANT: It is unlikely that the installation of the Eagle Tree system will cause problems with radio range. But, as 
always, it is critical to do an antenna-down range check, per your jet/radio manufacturer’s instructions, after making any 
changes to your jet’s electronics (and frankly before every flight session). Eagle Tree recommends that the range check 
be done with the turbine running, to completely verify operation (if this can be done safely). 
 
Happy Flying! We’d love to see pictures of your installation and get your feedback. Just email us at
