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. For AMT Netherlands users, the Recorder must be powered with a 4 cell (4.8v pack).

Do you have an ECU that is not currently supported? If so, email us at info@eagletreesystems.com to help!

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.

Installing and Powering the Recorder in Your Jet

First, read the Seagull Pro Flight System user manual for overall Seagull installation information. The Recorder can be powered from your Jet’s receiver battery pack, via the included Y cables, or from its own battery, plugged into one of the Pro system’s servo connectors.

The AMT Netherlands ECU Interface REQUIRES a 4.8v battery pack. The other ECU Interfaces should operate correctly on either a 4.8v or 6v pack. See the Seagull Pro Flight System user manual for more information on powering the recorder.

Connecting the Jet ECU Cable

The Jet ECU Interface cable connects to the “GPS/EU Tx” port on the Pro Recorder, with the Brown wire to the left, as shown in Figure 1.

NOTE: If you have the EU TX, you must connect the TX to the “FCC” port, as shown in the figure. Before doing so, the recorder must be configured for this mode. Please see your Seagull Pro Flight System manual for information on how to do this, under the “Connecting the Seagull Transmitter to your Data Recorder” under the “Using GPS” subsection.

The other end of the cable plugs into your ECU as follows:

JetCat: the cable plugs into the Data Bus port of your ECU, or into the Data Bus port of your ECU sensor board. Additionally, the cable can be plugged into the second port of your GSU, if you desire to see both GSU and Seagull information about the ECU on the ground.

AMT Netherlands: the cable plugs into the 3 pin Telemetry wire of the ECU. If desired, a standard servo Y cable (NOT the custom Y cables included with the Recorder) can be used to ‘Y” the Data Terminal and the Seagull simultaneously.

FADEC: The cable plugs into the data port of the ECU. It might be possible to build a Y cable to allow simultaneous Data Terminal and Seagull operation, but we have not tested this.

Note: it is fine to hot plug and unplug the Seagull ECU cable to/from the ECU, as desired.

Configuring the Jet ECU Interface with the System

Configuration of the Seagull Pro system with the ECU Interface is straightforward.

First, make sure you have installed our latest application from the website, and updated the firmware on the Recorder and Dashboard, as described above in the Requirements section.

Once this is complete, run the application, connect the Recorder to USB, and choose “Tools, Jet ECU Setup.” Select the type of ECU you have, and click “OK.”. The application will then prompt you to attach the Dashboard to USB, and the “Seagull Dashboard Data Setup Utility” application page should appear, as shown below:
