Customer Specified Parameters
Customer specified parameters allow the engine to be configured to the exact needs of the application.Customer parameters may be changed repeatedly as a customer's operation changes."Engine Rating Parameter"
"Rating Number"
The rating number is the selected rating within a power rating family. The flash file defines the power rating family. The flash file can contain one to four ratings. The rating number defines the power rating that is used within the power rating family."Security Access Parameter"
"Security System Immobilizer Installation Status"
The "Security System Immobilizer Installation Status" allows the "Security System Immobilizer" to be "Installed" or "Not Installed"."ECM Identification Parameter"
"Equipment ID"
"Equipment ID" is the identification of the equipment that is assigned by the customer. The "Equipment ID" is only for reference only by the customer. The "Equipment ID" is not required by the Electronic Control Module (ECM).Parameter Table

"Equipment ID"        System Configuration Parameters
System configuration parameters affect the emissions of the engine or the power of the engine. System configuration parameters are programmed at the factory. Normally, system configuration parameters would never need to be changed through the life of the engine. System configuration parameters must be reprogrammed if an ECM is replaced. System configuration parameters do not need to be reprogrammed if the ECM software is changed. Factory passwords are required to change these parameters. The following information is a description of the system configuration parameters."Full Load Setting"
The "Full Load Setting" (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. If the ECM is replaced, the FLS must be reprogrammed in order to prevent a 268-02 diagnostic code from becoming active."Full Torque Setting"
"Full Torque Setting" (FTS) is similar to FLS. If the ECM is replaced, the FTS must be reprogrammed in order to prevent a 268-02 diagnostic code from becoming active."Rating Interlock"
The "Rating Interlock" is a code that prevents the use of an incorrect power rating and/or emission rating for a specific engine. Each horsepower rating and each emission certification has a unique code.When an ECM is replaced, this rating interlock code must match the code that is stored in the ECM. If the rating interlock code does not match the code that is stored in the ECM, both of the following situations will exist:
The engine will not run.
The 253-02 diagnostic code will be active.Note: The flash programming of a new "Rating Interlock" replaces the old "Rating Interlock".This code does not need to be programmed when the replacement ECM is for the same engine rating.If the ECM is for a different engine rating, then the following components may need to be changed: pistons, fuel injectors and other components. The engine information ratings plate must also be changed in order to reflect the new rating.Some systems such as the cooling system or the transmission may also require changes when the engine is rerated."Engine Serial Number"
When a new ECM is delivered, the engine serial number in the ECM is not programmed. Program the engine serial number to match the engine serial number that is stamped on the engine information plate."ECM Software Release Date"
This parameter is defined by the "rating interlock" and this parameter is not programmable. The "ECM Software Release Date" is used to provide the version of the software. The customer parameters and the software change levels can be monitored by this date. The date is provided in the month and the year.
