Abstract
Calibration for a vehicle electronic control unit (ECU) includes determining a trigger event configured to initiate a check for updates to calibration data files of the ECU, iterating through calibration part numbers present in the ECU, and accessing, from a memory device in communication with the vehicle, in response to the iterating, a chain of parts table in a linked list that maps calibration part numbers identified in the ECU unit to any subsequently-issued calibration part numbers. The subsequently-issued calibration part numbers reflect an index to the updates to the calibration data files. The calibration also includes searching the chain of parts table using the calibration part numbers identified in the ECU to determine a corresponding subsequently-issued calibration part number, selecting one of the updates to the calibration data files using the subsequently-issued calibration part number from the memory device, and updating the ECU with the selected update.
