BOLT 8T4137 - Caterpillar

System configuration parameters are parameters that affect emissions and power of the engine applications. Default values for the parameters are programmed at the factory. Some parameters may be changed by the customer in order to suit the needs of the specific application. Proper values for these parameters are available on the electronic service tool. Certain configuration parameters are also stamped on the engine information plate.No password is required for programming a new Electronic Control Module (ECM) during the first 100 hours of service life. This 100 hour “free configuration” feature enables the customer to tailor the programmable setpoints to the requirements of the installation. Exceptions are "Fuel Limit" and "Personality Module Mismatch".Note: If the parameters that are protected with the factory passwords are changed, the Caterpillar warranty may be voided.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."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
