# EFI DLA Driver
|
||
|
|
|
||
|
|
This driver implements support for the DLA EFI serial protocol for
|
||
|
|
this system:

|
# Parameters
|
||
|
|
|
||
|
|
The script used the following parameters:
|
||
|
|
|
||
|
|
## EFI_DFA_ENABLE
|
||
|
|
|
||
|
|
this must be set to 1 to enable the driver
|
||
|
|
|
||
|
|
## EFI_DFA_LPS
|
||
|
|
|
||
|
|
This sets the fuel consumption rate in litres per second of injector
|
||
|
|
time. This will need to be tuned per engine to give the right value
|
||
|
|
for fuel usage and total fuel
|
||
|
|
|
||
|
|
# Operation
|
||
|
|
|
||
|
|
This driver should be loaded by placing the lua script in the
|
||
|
|
APM/SCRIPTS directory on the microSD card, which can be done either
|
||
|
|
directly or via MAVFTP. The following key parameters should be set:
|
||
|
|
|
||
|
|
- SCR_ENABLE should be set to 1
|
||
|
|
- EFI_TYPE should be set to 7
|
||
|
|
- EFI_DFA_ENABLE should be set to 1
|
||
|
|
- SERIALn_PROTOCOL should be set to 28 for the connected EFI serial
|
||
|
|
- RPM_TYPE1 should be set to 3
|
||
|
|
- ICE_ENABLE should be set to 1
|
||
|
|
|
||
|
|
then the flight controller should rebooted and parameters should be
|
||
|
|
refreshed.
|
||
|
|
|
||
|
|
Once loaded the EFI_DLA parameters will appear and should be set
|
||
|
|
according to the parameter list above.
|
||
|
|
|
||
|
|
The GCS will receive EFI_STATUS MAVLink messages which includes RPM,
|
||
|
|
cylinder head temperature, injection timing, engine load, fuel
|
||
|
|
consumption rate, throttle position atmospheric pressure and ECU
|
||
|
|
voltage.
|
||
|
|
|
||
|
|
Note that this EFI system only sends data when the enable PWM enable
|
||
|
|
signal is high. If that is hooked to the ignition control in ArduPilot
|
||
|
|
ICE system then you won't see any data until you start the engine.
