SHOE-TRACK 3563429 - Caterpillar

Programming Parameters
The Electronic Ignition System's control module (EIS control module) and the Electronic Control Module (ECM) have several parameters that can be programmed for the individual installation. The Digital Diagnostic Tool (DDT) or the Caterpillar Electronic Technician (Cat ET) is necessary for programming the parameters.The parameters are grouped into the following three menus on the DDT: "CUSTOMER SPECIFIED PARAMETERS (C.S.P.)", "TIMING" and "O2 TEST". Refer to Table 1 for the names of each parameter.Refer to Systems Operation/Testing and Adjusting, "Electronic Control System Parameters" for the descriptions of the parameters.

AFRC     "A/F RATIO P-GAIN"     "Air/Fuel Proportional Gain"    
AFRC     "A/F RATIO I-GAIN"     "Air/Fuel Integral Gain"    If a module is replaced, the appropriate parameters must be copied from the old module. The settings can be recorded on paper and then programmed into the new module. Alternatively, this can be done with the "Copy Configuration" feature of the Caterpillar Electronic Technician (ET).
Changing the parameters during engine operation can cause the engine to operate erratically. This can cause engine damage.Unless you are otherwise instructed, only change the settings of the parameters when the engine is STOPPED.
