System Configuration Parameters
System Configuration Parameters are those that affect emissions or horsepower of the engine. They are programmed at the factory and would normally never need to be changed through the life of the engine. System Configuration Parameters must be reprogrammed if an ECM is replaced, but not if the Personality Module is replaced (unless the engine rating changes). Proper values for these parameters are stamped on the engine information ratings plate located on the valve cover or intake manifold. Factory Passwords are required to change these parameters. A brief description of the System Configuration Parameters is described below.Engine Serial Number
Should be programmed to match the engine serial number stamped on the ratings plate. A new ECM is delivered with the engine serial number programmed to 0XX00000.Full Load Setting
Number representing fuel system adjustment made at the factory to "fine tune" the fuel system. Correct value for this parameter is stamped on the engine information ratings plate. This parameter must be programmed or a Diagnostic Code 253-02 Check Customer Or System Parameters (56) will be generated.Full Torque Setting
Similar to Full Load Setting. This parameter must be programmed or a Diagnostic Code 253-02 Check Customer Or System Parameters (56) will be generated.Personality Module Code
Code which prevents use of incorrect personality module for this engine. Each horsepower family and emission certification has a different code associated with it. This code (stored in ECM) MUST match that in the personality module or a Diagnostic Code 253-02 Check Customer Or System Parameters (56) will be generated and the engine will only run at low idle. When rerating the engine, programming this code to "0" will prompt the ECM to read and match its stored code to the Personality Module Code. Note that this code DOES NOT need to be programmed when a personality module is replaced, as long as the new module is of the same family and emission year. If the Personality Module is of a different family, then pistons, injectors, etc. may need to be changed and the engine information plate should also be changed to reflect the new rating. Some vehicle systems, such as the cooling system or transmission may also require changes when uprating an engine.Customer Specified Parameters
Customer Specified Parameters allow a customer to decide how a operator operates the machine. Some parameters may affect engine operation in ways an inadequately trained operator does not expect. These parameters may lead to power or performance complaints, even when the engine is performing to specification.Customer parameters may be changed repeatedly as a customer changes his operation or as new operators are assigned to a machine. Customer Passwords are required to change these parameters. The following is a brief description of the Customer Specified Parameters. Along with each are the minimum and maximum values for the parameter and the default value. The parameter value shown in BOLD is the programmed setting to disable a feature.Engine Power Rating Selection Number
Number of rating within the power family. The Personality Module defines the power family and may contain several ratings within that family. The rating number defines which rating is used (such as 325 hp @ 1900 rpm or 325 hp @ 2100 rpm) within the family.Vehicle ID
Identification of the machine assigned by the customer. Used only for customer reference, not required by the ECM.
