No registered ECU found and being prompted for license after flashing:

If one is being prompted for a license after flashing it could be because:

  1. There is an intermittent connection in the bench or bike side program harness. (Check the wiring)
  2. After a confirmed write, at the end not physically disconnecting the ecu before attempting to write another file. (Disconnect ecu after each write/attempt.)
  3. Starting with the tuning cable and power connected to the ecu before starting to write and when prompted to connect or disconnect, just clicking ok and not physically doing that. (Please follow all prompts to ensure the ecu is put into program mode.)
  4. Writing a file that does not match the ecu pn can prompt for a license and toggling between the wrong and right file. (Ensure the files match the ecu pn.)
  5. The ecu is not the same one that was last flashed with the license. (Verify it is same ecu).

These are just the most common issues why one is prompted for a license.
