RING 4M1634 - Caterpillar

Programmable parameters enable the engine to be configured in order to meet the requirements of the application. The system configuration parameters must be programmed when the application is installed. Perform this programming before the initial engine start-up.Data from a gas analysis and data on engine performance are required in order to determine the correct settings for the ignition timing and the exhaust oxygen. Incorrect programming of parameters may lead to complaints about performance and/or to engine damage.Programmable parameters can be classified into the following types: engine identification, timing control, air/fuel ratio control, speed control and start/stop control.If the Electronic Control Module (ECM) is replaced, the appropriate parameters must be copied from the old ECM. This can be done with the "Copy Configuration" feature of the Caterpillar Electronic Technician (ET). Alternatively, the settings can be recorded on paper and then programmed into the new module.
Changing the parameters during engine operation can cause the engine to operate erratically. This can cause engine damage.Only change the settings of the parameters when the engine is STOPPED.
