Starting Engine - Desert Aircraft DA 100 EFI Owner's Manual

DESERT AIRCRAFT OWNER'S MANUAL HFEDCN0054 Rev G
1. Throttle commands use the standard output from Channel 3 of the receiver.
Expected pulse width range from 900µs for closed throttle and 2100µs for wide
open throttle. You may need to extend the end limits for channel 3 in your
transmitter to produce the appropriate range. Adjust the exponential rate to get
the desired throttle response.
2. (Throttle Kill) Using the DA EFI system does not require an opto kill for proper
operation. When the pulse width from the receiver falls below 960µs (5%
throttle), the ECM will remove power to both the injector and ignition system
thus stopping the operation of the engine.
3. (UAV Option) Provide power to the enable line, when power is removed ECM
will remove power to both the injector and ignition system thus stopping the
operation of the engine.
FUEL SYSTEM WARNINGS:
Do not connect the fuel port to the Manifold Air Pressure tube.
Do not exceed 15 PSI (1 bar) of fuel pressure.
c. Starting Your Engine for the First Time
1. Verify that the ECM is powered up (Blue Light on ECM).
2. Verify that the throttle setting is at about 30%.
3. Prime your system for the first time by removing the fuel line from the back of
the throttle body. Cycle the battery power to the ECM in 5 second intervals
until fuel is flowing from the fuel line. Re-install the fuel line. You should not
have to complete the priming process again unless the engine fuel system is
allowed to run dry or has been disconnected for any reason.
4. Give the prop several aggressive flips, the engine should start.
