maybe X17 wrong checksum calculation!

Modify one single byte in your dump and write it to the car. This way you will know if it is checksum problem or not.

As I said, modify just 1 byte, then you will know if it is chks problem or not.

I can't update my x17 for the moment, i can't download exe
i think it's CKS problem, i think test write with galletto v54, maybe CKS is ok on this tool
