Situation:
The data base file is modified to meet the expectations of the new car line. But the ECU should be used for both, the "old" car line 2002 and the new one 2008. The changes within the data base file can be extensive. Perhaps messages are modified and transport now completely different information. So you have Multiple Configurations within one ECU.
Solution:
Develop the software for both car lines. Handle each car line like a virtual channel. Define the ECU to be car line 2002 or car line 2008 by a single function call at startup.
