G3500 A3 Engines Caterpillar

Certain parameters are unique for each engine application. Table 1 is a list of the parameters that can be configured for G3500 Engines. The parameters are programmed into the Electronic Control Module (ECM) via the Caterpillar Electronic Technician (ET). The values of the parameters can be viewed on the "Configuration" screen of Cat ET.

Most of the parameters are common to engines that use oxygen feedback and to engines that use charge density. However, some of the parameters are associated only with oxygen feedback or with charge density.

Refer to Systems Operation/Testing and Adjusting, "Electronic Control System Parameters" for the descriptions of the parameters.
