    AS far i know, there is possible to read and write using Ktag Ori, but checksums are not calculated so file is useless. Has anyone know any other tools that could read and write ems 2.3 sucsessfully?

    Yes this is true. I have Ktag ori and support told me that i can read write but cannot calculate checksum.
    Can someone else write to support for connection beacuse they send me only file that i atached on post before but for me there is no connection picture in file

    Is there any news on EMS 2.3? I understand correctly that a ktag can read-write a dump, but there is no calculation of the checksum of the dump and there is no possibility to make changes?

    Yes, exactly that what you tell.
    No possibility to calculate cheksum= no posibility to make changes.

    Can I read the memory from one EMS 2.3 (is it new, works well) and write it to another new ECU EMS 2.3? Any protection for the serial number or processor ID is present?

    There is no possibility to clone this ECU - just checked with Dimsport

    Since 21.05.2019 New Trasdata supports reading/writing EMS2.3 but not checksum
