Equipment ID
The customer can assign an "Equipment ID" for identification for the engine application.Engine Serial Number
The engine serial number is programmed into the ECM at the factory. The number is stamped on the engine information plate.Passwords
Customer Password #1 and Customer Password #2
The "Customer Password #1" parameter and the "Customer Password #2" parameter can be defined by the customer. The passwords are used to protect certain configuration parameters from unauthorized changes. Refer to Troubleshooting, "Customer Passwords" for details.Security Access Parameters
CAN Communication Protocol Write Security
CAN Communication Protocol Read Security
Total Tattletale
This parameter is used to display the number of changes that have been made to the configuration parameters.Timing Control
The "Desired Timing" parameters allow the customer to program the timing of the ignition spark of the electronic system to meet the needs for specific applications and specific installations. The desired timing value can be changed while the engine is running or while the engine is stopped. The value that is entered for the desired timing is the ignition timing when the engine is operating at rated speed and at full load.Note: The actual ignition timing at a given instance may vary from the desired timing value. This variance is due to variations in the engine speed or the detonation.The range for programming the desired timing is 4 degrees to 25 degrees before the top center (TC) position."First Desired Timing"
The "First Desired Timing" is determined with the methane number of the primary fuel that is used.Use the Engine Performance Sheet, "Fuel Usage Guide"Note: Determine the desired timing by using the Caterpillar Software , "Gas Engine Rating Pro (GERP)" with the results that are from the fuel analysis. Use of only the data from the gas analysis can result in incorrect settings.Note: The timing select switch input at terminal 44 of the J1 ECM connector, must be open circuit (not connected to ground), for the ECM to use the programmed "First Desired Timing".Air/Fuel Ratio Control
Before the initial start-up, a current gas analysis is required. Periodic gas analyses are
