    Exclamation ECU type of fiesta ecoboost 1.0 and Controller unlocker x35 invalid key

    hello all
    I have bought a mpvi2 and try to tune my fiesta ecoboost 1.0. but i have got a Controller unlocker x35 invalid key message and stop reading.
    Does anyone know how to solve that and who knows the ecu type of fiesta ecoboost 1.0?(because it can't be read by mpvi2 )
    I have tried MED 17.0.1 and MED 17.2 but still error.

    You get that message when the selected controller is not correct. It is also possible that the controller in your car is not supported.
