1.8 Correction values for injectors
The function "Adaptation of correction values for injectors"
serves to correct the injection rates for each cylinder of a com-
mon rail system individually across the entire ignition map
range.
The 7-digit correction values -1- (details in illustration are only
an example) are marked separately on each injector. The
marked values may consist of letters and/or numbers.

After renewing the engine control unit, the "correction values for
the injectors" must be transferred to the new engine control unit.

tion values, and store them in engine control unit
