Introduction
UAV EFI for DLE engine is an Electronic Fuel Injection conversion kit for the UAV engine.
It is a bolt-on EFI kit to a lot of small engines. For example, DLE-40, DLE-60, DLE-120,
DLE-170 etc. We can supply the suitable EFI kit for most of UAV engines. The
displacement of the engines can be in the range of 20cc to 300cc, and even larger
engines.
This UAV EFI kit has below features:
Electronic fuel injection (EFI)
Quick engine start even at cold temperatures
More power and torque than the carbureted version
High fuel efficiency and low carbon emissions
OBD - on board diagnosis
Performance tuning for advanced users.
Altitude compensations
Transient fuel compensations
Servo motor control (optional)
Ignition control (optional)
Parts:
1. ECU
2. Harness (including the connectors)
3. Throttle Body
Throttle body
Servo motor(included)
TPS sensor(optional)
Fuel injector (mounted on the throttle body)
4. Fuel pump assembly
Rotary fuel pump with pressure regulator (outside of the tank, 25L/h))
5. Baro sensor (integrated in ECU)
6. Engine temperature sensor
7. Intake air temperature sensor
8. Ecotrons CDI - ECU controlled (optional, you can use your own CDI).

9. Serial communication cable (to a computer)
10. USB adaptor - included
11. CD for tuning software (downloadable from our website)
Note:The kit requires a 12V battery by default.

Chapter 1 EFI installation
1.1 Remove the stock carburetor and install the
throttle body
Note: the stock DLE 120 carburetor is about 22mm diameter outlet. The Ecotrons throttle
body is also 22mm diameter. So it is a bolt-on replacement.
Note: Ecotrons Small throttle body is designed to replace the stock carburetor and has
the same or similar spacing as the carburetor, so that you can bolt on the throttle body.
Ecotrons throttle body is designed to mount the Futaba servo motor easily. So the
complete throttle body / servo is compact and light.
Ecotrons Small throttle body is designed to mount Ecotrons’ small engine injectors. It
comes with the injector fittings and thread-on fuel lines. The injector flow rates: 30g/min,
38, 60, 80, 128, 190, 248g/min etc.

And we also have 14mm, 18mm, 22mm, 28mm throttle body for UAV engines, so we can
provide the UAV EFI kit for different engines with different displacement.
Some engines, you can use the throttle body to replace the carburetor completely, and
for some engines, you need make the adapter to bolt on the throttle body.
Note: Some custom system comes with the throttle position sensor, so if you want to use
the throttle position sensor, you also need to install the TPS sensor on the throttle body.
Note：Because the stock blot is too long, so you cannot use them to bolt on the throttle
body directly. You may need to add a suitable washer/ nut, as shown in this picture.
Or cut the stock blot short.

1.2 Install the fuel supply system
Customers have to find a good location to install the fuel pump. By default, the
fuel pump should be lower than the fuel tank.
The fuel feed inlet in the tank should be submerged in the fuel all the time.
There should be an inline fuel filter.
Note: The EFI has a fuel pressure regulator which requires a fuel return line
back to the fuel tank.
