Instruction Manual for the Seagull Jet ECU Interfaces
Document Version 1.2
Model #’s ECU-JETCAT, ECU-AMT, ECU-FADEC
Thank you for your purchase! This instruction manual will guide you through the installation and operation of your Seagull
Jet ECU Interface. Please read the entire manual carefully before proceeding. If, after you read the manual (including the
Troubleshooting section!!), you have further questions or problems, see the Support page on
Features and Benefits of the Jet ECU Interface
The Jet ECU Interface, in conjunction with our Seagull Pro Flight System, provides real-time data and audible feedback
about the state of your Model Jet, while you are flying! Think of the Jet ECU Interface as a Wireless Engine Data
Terminal/GSU for your Jet.
Data such as ECU Turbine RPM, Turbine temperature, Throttle %, ECU Pack and Pump Voltage, and ECU status
messages are retrieved from your ECU and transmitted wirelessly to the Seagull Dashboard. Audible alarms can be
programmed for low Turbine RPM and temperature for early flameout alert, and for ECU pack voltage for low battery
indication. All these parameters are in addition to the standard data parameters that are available on the Pro System.
In addition to display on the LCD screen of the Wireless Dashboard, if the Dashboard is connected to a laptop via USB,
all the ECU data are available live with the Windows Virtual Cockpit application!
Packing List
Your package should include the following: Jet ECU Interface Cable (either AMT Netherlands, JetCat or FADEC), and a
printed version of this manual. Please check your box for printed addenda to this manual which may be included if
changes were made after printing.
Requirements
The Jet ECU Interface requires a Seagull Pro Flight System, with Windows application version 3.39 or later. The latest
version is available on the support page of our website. The Recorder and Dashboard firmware needs to be updated using
“Tools, Firmware Control.”
For JetCat users, version 4.00g of the JetCat ECU is required.
powered with a 4 cell (4.8v pack).
For AMT Netherlands users, the Recorder must be

How the Jet ECU Interface Works
The Jet ECU Interface cable plugs between the Pro Flight Recorder the data/telemetry port of your ECU. After simple
Windows configuration, the Recorder reads the ECU parameter data and transmits it to the Wireless Dashboard.

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

Include a full description of your problem, your machine configuration, brand/model/version of ECU, application version,
Dashboard and Recorder firmware version and any other relevant details.
Issue: “ECU NOT DETECTED” appears on the ECU Status page of the LCD Dashboard, after configuration
Solution:
•
Make sure you have downloaded the latest Windows application and installed the latest firmware, as described in
the Requirements section above.
•
•
•
Make sure you have followed the application configuration instructions above.
Make sure that you have connected the ECU Interface cable appropriately, as described above.
Plug in your Engine Data Terminal/GSU, if you have one, and verify that it is reading correctly.
Issue: I have reduced antenna-down range with the ECU Interface installed
Solution:
•
Try isolating the problem – disconnect the ECU Interface cable, and see if the range improves. If it does not
improve, please see the Troubleshooting section in the Seagull Pro Flight System user manual. If range does
change when disconnecting the ECU Interface cable, please contact Eagle Tree Systems immediately.
