889833045 Mercury SCREW, (M8 x 45)

System configuration parameters are parameters that affect emissions and power of the engine. 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. Values for these parameters can be viewed on the electronic service tool. Certain configuration parameters are also stamped on the engine information plate.No password is required for programming a new 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 Table

"Personality Module Interlock"
The "Personality Module Interlock" is automatically programmed by the ECM after factory passwords are entered."ECM Serial Number"
The "ECM Serial Number" is stored in the memory of the ECM. The "ECM Serial Number" can be accessed by the use of the service tool."Engine Serial Number"
Program the "Engine Serial Number" to match the engine serial number that is stamped on the engine information plate.Note: When you are requesting factory passwords, always use the engine serial number that is resident in the ECM."Equipment ID"
"Equipment ID" allows the customer to enter a description into the ECM in order to identify the engine. 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."Full Load Setting (FLS)"
"FLS" is a number that represents the adjustment to the fuel system that was made at the factory. The factory adjustments are made in order to fine-tune the fuel system. The correct value for this parameter is stamped on the engine information plate. Factory passwords are required."Full Torque Setting (FTS)"
"FTS" is similar to "FLS". Factory passwords are required."Fuel Ratio Control (FRC)"
The "Fuel Ratio Control" limit controls the amount of fuel to air ratio. Control is accomplished 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."Fuel Correction Factor"
"Fuel Correction Factor" is a programmable offset that is used to improve the accuracy of the calculated fuel usage."Low Idle Speed"
"Low Idle Speed" is the minimum allowable operating speed for the engine."Ether Solenoid Configuration"
The "Ether Solenoid Configuration" defines the installation status of an ether starting aid for the engine."Idle Cylinder Cutout"
The "Idle Cylinder Cutout" will determine the availability of a cylinder cutout test at idle.
