I wonder if anybody could help me understand a couple of things about BMW software versioning.

1. If you take an a2l version/epk (e.g. R1C2J8B3B), then there might be Bosch MG1CS003_B58_<VERSION>_x_DE_SWCalDoc.pdf but the BMW application export has a different, apparently unrelated name related to a program status (e.g. 209a_071_010_001). Is there a way to make the correspondence between a2ls and a matching BMW application export?

2. Calibration files have this additional id, e.g.
PRG (HEX): 3076501103
This looks like maybe a checksum of a specific calibration bin? Could anybody expand on or correct me please?

Thanks in advance.
