The "Rating Selection" corresponds to the selected set of performance maps for the application. This selected set of performance maps comes out of several unique sets of maps that may be resident in the flash file. Changing the "Rating Selection" may create a mismatch in the interlock code.
The "ECM Serial Number" identifies the ECM that is installed on the engine. If the ECM is replaced, the ECM serial number must be programmed with factory passwords.
Program the "Engine Serial Number" to match the engine serial number that is stamped on the engine information plate. If the ECM is replaced, the engine serial number from the engine information plate must be programmed into the new ECM.
"Equipment ID" allows the customer to enter a description into the ECM in order to identify the installation. 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.
"Personality Module Part Number"
The "Personality Module Part Number" is the part number in the Caterpillar system that indicates the software version that currently resides in the engine ECM.
"Personality Module Release Date"
The "Personality Module Release Date" is the date of release for the software in the personality module.
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.
The "Total Tattletale" parameter counts the number of changes to system parameters.
"Low Idle Speed" is the minimum allowable operating speed for the engine.
"Engine Acceleration Rate" is the maximum ramp rate in order to reach desired engine speed.
The "Engine Speed Droop" determines the change in the reduction of engine speed at full load from the engine speed at no load. Droop can be adjusted for stability of engines with different rates of speed changes. "Engine Speed Droop" allows the operator to equalize the load between engines that are operating in parallel.
"Droop Mode Selection" allows the customer to select either droop or isochronous mode.
"Droop/Isochronous Switch Enable"
The "Droop/Isochronous Switch Enable" allows the customer to enable the "Droop Mode Selection" parameter.
"FLS" is a number that represents the adjustment to the fuel system that was made at the factory 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.
"FTS" is similar to "FLS". Factory passwords are required.
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.
This parameter allows the customer to lock out certain parameters by entering a password. Customer passwords must be used to unlock any parameters that are protected by customer passwords before the parameter can be changed. Factory passwords are required if this password is lost.
This parameter allows the customer to lock out certain parameters by entering a password. Customer passwords must be used to unlock any parameters that are protected by customer passwords before the parameter can be changed. Factory passwords are required if this password is lost.

Note: Compare the FLS and the FTS from the ECM with the values that are listed on the Engine Information Plate. The FLS and the FTS should only be changed because of a mechanical change in the engine. The use of the wrong parameters could cause damage to the engine. The use of the wrong parameters may also void the Caterpillar warranty.
