When trying to read my ECM for the first time too try and collect files to send too my tuner, the process will get too about 40% and then stop and say "failed" and "controller Unlocker x36 exceed number of attempts". I have contacted the previous tuner too see if the ECM may have been locked for their tune but they said they do not ever lock their tunes. I just wanted too see if there is ANY trouble shooting that might be able to be done. i have made sure the MPVI3 is securly connected to the OBD2 and too the computer aswell and cannot seem to find any recources online. Any help is appreciated
