Injector phasing is defined in the window above.
Injector Name
– The injector output. See application pinout sheet or schematic for more
information.
Active
– Enables or disables an injector output. Note that a power cycle is necessary after
making changes to these settings.
Knock Sensor #1
– Assigns an injector to a knock sensor input. Fuel changes defined in the
knock control function will be applied according to these settings. The number of knock sensor
inputs varies by application. See pinout sheet or schematic for more information.
O2 Feedback
– Assigns an injector to an O2 sensor input. Fuel changes defined in the O2
feedback control function will be applied according to these settings.
EGT Feedback
– Assigns an injector to an EGT sensor. EGT fuel trims will be applied
according to these settings. The number of EGT sensor inputs varies by application. See
pinout sheet or schematic for more information. Note that the EMS-4 systems do not have EGT
sensor input circuits.
Injector Type
– Defines an injector as “Base” if staged injection is not being used, “Primary” if
used as a primary injection in a staged setup or “Secondary” if used as a secondary injector in a
staged setup.
Injector Phasing
– Defines the injector phasing. In the example above, the injector outputs will
fire in order 1
– 2 – 3 – 4 every 6 teeth.
Alternative setup
– Injectors outputs fire in “Cylinder Firing Order”
