Tested now a downgrade flash from 54.3 to 52.x
Result was, although i had now old cafd in NBT, CAFD were not readable
Only older psdzdata helped to make the same old CAFD readable.
i took a look at the 54.3 data and compared it to the 54.2 data. it seems that the older versions are trimmed. some files with newer numbers have the same size like the 54.2 files. has someone tried a car with the 54.3 data programmed and then read it out? it could be that the older files are trimmed and only the newest are ok. i need to compare the files next week.
Of course, because cafd-files on newest psdzdata are trimmed versions.
It was not so clear, because logical was that with 54.3 all new cafd s up from 54.3 have trimmed files, nobody said that also older cafd which normaly related to older psdzdata are affected in 54.3
Now i know it and its good to see in shawns comparison.
But not all cafd are affected, in my case older cafd from fem was not trimmed as NBT
