INF Inject Driver

This driver implements support for the INF Inject EFI engine control units.

Parameters

The script used the following parameters:

EFI_INF_ENABLE

this must be set to 1 to enable the driver

EFI_INF_OPTIONS

This sets options for the driver. Currently the only option is to set EFI_INF_OPTIONS to 1 to enable logging of the raw serial bytes to a file called INF_Inject.log

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
SCR_VM_I_COUNT should be set to at least 50000
EFI_TYPE should be set to 7
EFI_INF_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_INF_ENABLE 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, exhaust gas temperature, injection timing, engine load, fuel consumption rate, throttle position atmospheric pressure and ignition voltage.
