Parameter Descriptions
"Injector Codes"
Note: The injector codes are not part of the "Configuration" screen on the electronic service tool. "Injector Codes Calibration" can be found under "Calibrations" in the "Service" menu on the electronic service tool.The injector code is a number that is found on each of the unit injectors. The ECM uses this number to compensate for manufacturing variations between individual injectors. If you replace any of the unit injectors, you must reprogram the code for the new injectors. Also, if you replace the ECM, you must reprogram all of the injector codes."Fuel Ratio Control"
The "Fuel Ratio Control" limit controls the amount of fuel to air ratio by limiting the rack as a function of boost pressure, engine speed and altitude. The "Fuel Ratio Control" function permits an offset to be applied to the calculation for the altitude. The offset changes the fuel to the air ratio to a richer mixture or a leaner mixture."Rated Fuel Position"
This parameter is used to limit the engine power. A factory password is required to change this setting.Direct Fuel Control Mode
The "Direct Fuel Mode" allows the use of an external governor to control engine speed.The governor-to-engine interface is identical to that of the large line of Woodward “EG-XXX"” electrohydraulic actuators. These electrohydraulic actuators use the same drive signal and input impedance.Only governors that have been designed to drive a Woodward “EG-XXX” actuator will interface and function properly in this mode.The customer must install the components for the direct fuel control in order to operate in direct fuel control mode. These components include the following:
An inductance coil
A resistor
A module that converts the DC governor signal to a nominal 500 Hz PWM signalOn the Cat ET, the configuration parameter must be programmed to "ON" in order for the Electronic Control Module (ECM) to respond properly to the external governor. The following functions are not used in direct fuel control mode:
Low idle
Start fuel limit
Crank terminate speed
Cooldown speed"Engine Cooling System Configuration"
This parameter is used as a switch to toggle between the SCAC cooling system or the JWAC cooling system."Cold Cylinder Cutout"
The cold cylinder cutout automatically stops fuel injection to cylinders that are not firing. The fuel injection is stopped to the cylinders until the engine reaches operating temperature. "Cooldown Engine Speed"
This parameter defines the engine rpm level when the Engine Control Switch (ECS) is placed in the STOP position."Engine Cooldown Duration"
This parameter defines engine operation at the cooldown speed. Programming this parameter to 0 will disable this function."Engine Prelube Duration"
This parameter sets the engine prelubrication timeout period. Programming this parameter to 0 will disable this function."Crank Duration"
The crank duration determines when the starting motors will be energized. The crank duration determines when the starting motors will be disengaged. Programming this parameter to 0 will prevent the ECM from engaging the starting motors."Maximum Number of Crank Cycles"
This parameter is the total number of crank cycles that can be performed."Crank Terminate Speed"
This parameter determines when the starting motor will disengage."Total Tattletale"
The parameter counts the number of changes to system parameters.Parameter Table

"Equipment ID"
"Equipment ID" allows the customer to enter a description into the ECM in order to identify the vessel. A maximum of 17 characters may be entered in the field. This parameter is only for reference by the customer. This parameter is not required."Engine Serial Number"
"Engine Serial Number" should be programmed to match the engine serial number that is stamped on the engine information plat
