Maybe the map is internally changed the Def name in the hex file, might wanna DL tiny hexer and look into it in line 2000 and close to the bottom line is the name of your def, for example, mine is: A4RM200K. Change the name for the map for your ecu accordingly, and check and re-check for defs.
Hope it helps, pm for any trouble.
Most people change the name if their custom maps to avoid some sort of "copying"
