Mode B

Quantity correction output by selected cylinder In this test mode, the engine is running with the fuel balancing control (FBC) correction values enabled. The correction quantity shows an offset, which is added to the injected quantity to establish a vibration-free running of the engine. The cylinder selective engine speed is also provided. A higher cylinder balancing quantity correction shows an injector, which needs greater time to inject an amount of fuel to produce the requested torque.
