If you receive this Error message when trying to write your ECU it is caused from a File Mismatch. You will need to double check your map and your ECU part number and to be sure you have selected the proper file.

What to do if there isn't a map matching the ECU?
Hello,
That depends on the make and model. Some ECU's you can read and send us the file to be defined and some you will have to send us the ECU for us to define. What bike are you working with?
