Parameter Descriptions
"Product ID"
The "Product ID" parameter allows the customer to enter a description into the ECM in order to identify the machine. A maximum of 8 characters can be entered in the field."Equipment ID"
The "Equipment ID" parameter allows the customer to enter a description into the ECM in order to identify the machine. A maximum of 17 characters can be entered in the field."Engine Serial Number"
The "Engine Serial Number" should be programmed to match the engine serial number that is stamped on the engine information plate. The engine serial number is not preprogrammed on a replacement ECM."FLS" (Full Load Setting)
"FLS" is a number that represents the adjustment to the fuel system that was made at the factory in order to fine tune the fuel system. The correct value for this parameter is stamped on the engine information ratings plate. This value should only be changed if the engine is rerated or a new ECM is installed. Factory passwords are required."FTS" (Full Torque Setting)
"FTS" is similar to "FLS". This value should only be changed if the engine is rerated or a new ECM is installed. Factory passwords are required."Throttle Lock Engine Speed Limit"
The "Throttle Lock Engine Speed Limit" parameter allows the maximum engine speed (rpm) for the throttle lock to be programmed within the available range."Ether Control"
The "Ether Control" parameter allows the operation of this feature to be enabled or disabled."System Battery Voltage Low Elevated Idle"
The "System Battery Voltage Low Elevated Idle" parameter allows the operation of this feature to be enabled or disabled. Refer to Troubleshooting, "Elevated Idle" for more information.Parameter Table
