Carrying out adaptation for injector delivery calibration
Carrying out adaptation for injector delivery calibration
The „injector delivery calibration (IMA)“ function serves to correct the injection rates for each cylinder of a common rail system individually across the entire ignition map range.
The 7-digit adaptation 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 an injector, the adaptation value must be written into the engine control unit.
After renewing the engine control unit, the „adaptation values for the injectors“ must be transferred to the new engine control unit.
The adaption procedure is described in Guided Fault Finding. (Description under "Guided Functions".)
Additionally check that the „injector delivery calibration values“ are correctly entered for all the other injectors. Do not attempt to re-enter these values if the correct values are already stored in the engine control unit.
