CYLINDER HEAD GP 2192955 - Caterpillar

the engine is shipped from the factory, an estimate of the engine fuel consumption is programmed into the Electronic Control Module (ECM). The fuel consumption estimate is based upon the engine performance specifications. The actual fuel consumption can be determined with a precision fuel flow meter. Customers are likely to find a slight difference between the programmed fuel consumption and the actual fuel consumption. The customer can use the Cat® Electronic Technician (ET) to program the ECM for the actual fuel consumption. No password is required in order to change this configuration parameter.In order to program the ECM for the actual fuel consumption, change the Fuel Correction Factor (FCF) that is already programmed into the ECM. The FCF can be programmed in increments of 0.5 percent between 20 percent.
