3. You apply the 001_002_003 ncd file to the 002_003_004 software version.
Isn't there some risk that the .ncd layout changed between 001_002_003 and 002_003_004 that would completely screw up the FDL data?
i.e. if you changed the value for RDC_SAFETY, are we sure that the value location in the saved .ncd file is always going to be in the same regardless of the software version?
I would think it would be safer to just re-code everything field by field with the new CAFD files.

Yes, If during dealer programming, the ECU CAFD was updated to a new version, that should be read and backed up as "original", then FDL Coded and backed up "as coded". If the CAFD was not updated, then the last "as coded" backup .ncd could be restored.
