Clone Kess if yes they had many problems in edc17, i would recommend to read and write with em.
If original one contact alientech.

If you got ktag, recommend to do backup of tricore. you also can tune there and upload via ktag.
Let ktag chks done.

Hello, are you loading the file with Winols? If so, Winols asks you when import file "calculate compatibility test checksum". Untick this box as only full bench reads will work correctly with EDC checksum parts. I assume that the tool is handling the checksum correction in this instance .
