RING 1920625 - Caterpillar

"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 used to encourage the driver to shift to the next highest gear.
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 best 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 ECM will not allow fuel to the engine above this limit. This parameter is used to encourage the driver to shift into overdrive or 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".
