MANIFOLD 5G9153 - Caterpillar

Fuel Ratio Control
The ECM determines the offset value for the Fuel Ratio Control (FRC). The FRC Offset value is used to adjust the fuel ratio control. This minimizes the exhaust smoke when the engine is accelerated.An offset value of 25 kPa ( 4 psi) may be used for adjusting customer preference, fuel quality or other factors that affect engine performance. The default setting is 0.Note: This parameter may not be available on all applications. This parameter is used in place of the mechanical control for the fuel to the air ratio. This parameter improves the engine response with improved emission levels.
Table 11
Minimum Default Maximum
-25 0 25 Ether Control
Programming this parameter to "DISABLED" will disable the ether functions. Program this parameter to "DISABLED" if the ether function is not being used or if ether is not installed on this engine. This will prevent the diagnostic codes for the ether control from being logged.

Minimum Default Maximum
Disabled Disabled Enabled "Data Link #2 Identifier"
The interface will allow you to control the engine from a remote site.

Minimum Default Maximum
Engine Control 1 Engine Control 1 Engine Control 8 Engine Cooling System
The engine can use the separate circuit aftercooler system (SCAC). The engine can use the jacket water aftercooler (JWAC).Note: The ATAAC is only available for the 3500C Engines. The ATAAC parameter is not selectable for 3500B Engines.

Minimum Default Maximum
JWAC SCAC ATAAC Cold Mode Cylinder Cutout
This parameter enables the strategy for the cold mode cylinder cutout.
Table 15
Minimum Default Maximum
Disabled Enabled Enabled Fuel Position Multiplier
This parameter decreases the power output from the engine by reducing the fuel. This parameter is used to control the driven equipment. A decrease in engine power does not require a change in the throttle.
Table 16
Minimum Default Maximum
Disabled Enabled Enabled Engine Acceleration Rate
This parameter limits the rate of change for the desired engine speed. This parameter may also help reduce smoke when you start the engine.
Table 17
Minimum Default Maximum
1 rpm per second 250 rpm per second 2000 rpm per second Injector Trim Code
Note: The injector trim code is not part of the "Configuration" screen on Caterpillar Electronic Technician (ET). "Injector Codes Calibration" can be found under "Calibrations" in the "Service" menu on Cat ET.The injector trim code is a number that is found on each of the unit injectors. The ECM uses this number to compensate for manufacturing variations between individual injectors. If you replace any of the unit injectors, you must reprogram the injector trim codes for the new injectors. Also, if you replace the ECM, you must reprogram all of the injector trim codes.
