CRANKSHAFT GP 1253005 - 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    
1100 rpm     TEL rpm     TEL rpm    "Lower Gears Turn Off Speed"
The "Lower Gears Turn Off Speed" parameter is the vehicle speed which turns off the "Lower Gears Engine RPM Limit". This must be matched with the "Lower Gears Engine RPM Limit" to the specific drive train for best performance.
Table 2
Minimum     Maximum     Default    
5 km/h (3 mph)    
48 km/h (30 mph)    
5 km/h (3 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    
1100 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    
8 km/h (5 mph)    
80 km/h (50 mph)    
8 km/h (5 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 top gear.
Table 5
Minimum     Maximum     Default    
1300 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
Minimum     Maximum     Default    
48 km/h (30 mph)    
204 km/h (127 mph)    
204 km/h (127 mph)    "Low Idle Engine RPM"
The "Low Idle Engine RPM" is the minimum engine rpm.
Table 7
Minimum     Maximum     Default    
600 rpm     750 rpm     600 rpm    "Transmission Style"
This parameter indicates the type of transmission configuration that is installed in the vehicle to the ECM. This parameter is used by the ECM to read the signals from the following devices:
Brake switch (No. 2)
Clutch switch
Neutral switchIf an automatic transmission is installed, program this parameter to one of the following options:
Automatic option 1
Automatic option 2
Automatic option 3
Automatic option 4The manual selection requires a clutch pedal position switch to be connected to the ECM connector J1/P1:24. The
