Table 1
Minimum Maximum Default
1500 rpm TEL rpm TEL rpm "Lower Gears Turn Off Speed"
The "Lower Gears Turn Off Speed" parameter is the vehicle speed when the "Lower Gears Engine RPM Limit" is shut off. This must be matched with the "Lower Gears Engine RPM Limit" to the specific drive train for optimum performance.
Table 2
Minimum Maximum Default
2 km/h (1 mph) 24 km/h (15 mph) 2 km/h (1 mph) "Intermediate Gears Engine RPM Limit"
This parameter is similar to the "Lower Gears Engine RPM Limit". The engine will accelerate at a slower rate when this limit is exceeded under normal driving conditions. This parameter is typically programmed to a slightly higher rpm than the "Lower Gears Engine RPM Limit".
Table 3
Minimum Maximum Default
1500 rpm TEL rpm TEL rpm "Intermediate Gears Turn Off Speed"
This parameter is similar to the "Lower Gears Turn Off Speed". This parameter is typically programmed to a slightly higher vehicle speed than the "Lower Gears Turn Off Speed".
Table 4
Minimum Maximum Default
16 km/h (10 mph) 80 km/h (50 mph) 16 km/h (10 mph) "Gear Down Protection RPM Limit"
This parameter is the engine rpm limit when the vehicle speed is above the "Gear Down Protection Turn On Speed". This is a hard limit. The Engine Control Module (ECM) will not allow fuel to the engine above this limit. This parameter is used to encourage the driver to shift into overdrive or into top gear.
Table 5
Minimum Maximum Default
1700 rpm TEL rpm TEL rpm "Gear Down Protection Turn On Speed"
This parameter is the vehicle speed when the "Gear Down Protection RPM Limit" is turned on. This must be matched to the specific drive train for best performance. Above this "Vehicle Speed Limit", the engine rpm will be limited by the "Gear Down Protection RPM Limit".
Table 6
Application Minimum Maximum Default
GM 48 km/h (30 mph) 121 km/h (75 mph) 121 km/h (75 mph)
Other 48 km/h (30 mph) 204 km/h (127 mph) 204 km/h (127 mph) "Top Engine Limit (TEL)"
This parameter is the maximum engine rpm when the engine is under load. The engine will still achieve rated rpm under no load conditions.
Table 7
Minimum Maximum Default
2640 rpm 2640 rpm 2640 rpm Note: Select ratings have a different "Top Engine Limit"."Low Idle Engine RPM"
The "Low Idle Engine RPM" is the minimum engine rpm.
Table 8
Minimum Maximum Default
700 rpm 800 rpm 700 rpm "Transmission Style"
This parameter is used to tell the ECM the type of transmission that is installed in the vehicle. This parameter is used to configure the ECM for the following inputs:
Brake switch 2
Clutch switch
Neutral switchesThe ECM must be programmed to one of the following options if an Allison Wt Automatic Transmission is installed:
AT/MT/HT Option 1
AT/MT/HT Option 2
AT/MT/HT Option 3
AT/MT/HT Option 4If any other automatic transmission is installed, program this parameter to one of the following options:
Automatic Option 1
Automatic Option 2
Automatic Option 3
Automatic Option 4If one of the manual options is selected, J1/P1:24 is used to receive a signal from a clutch pedal position switch. The message is also available from one of the supported J1939 sources. If one of the transmissions with a neutral switch is selected, J1/P1-62 Input #12 must receive a signal from a transmission neutral switch. This message is also available from one of the supported J1939 sources. If one of the transmissions with two brake switches is selected, the second brake switch must be connected to J1/P1:64 Input #13.
