Prefacelift & facelift EuroR ktuner

I recently bought a ecu with ktuner hardware. I tried to plug it in and upload a basemap, but it said error 251 when it tried to erase the ecu.

I wonder the ecu’s pin out on both preface or facelift are different, that cost the problem?

Much appreciated

251 means the unit could not contact the ECU on the little header to begin flashing. Either the unit, header, or ECU is damaged.
