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
Prefacelift & facelift EuroR ktuner
Re: Prefacelift & facelift EuroR ktuner
251 means the unit could not contact the ECU on the little header to begin flashing. Either the unit, header, or ECU is damaged.
