For descriptions of the parameters, refer to Systems Operation, "Electronic Control System Parameters". The values of the parameters can be viewed on the "Configuration" screen of Cat ET.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 fuel quality and for the specific gravity of the gas. Incorrect programming of parameters may
