I have been having trouble uploading my tunes using my X4. The last two uploads locked my PCM and it needed to be sent into SCT.
So....
They recommended that I run a bench tune setup. (example here: https://www.youtube.com/watch?v=go6AksH45II (https://www.youtube.com/watch?v=go6AksH45II) )
Does anyone have the wiring diagram for the OBD-II port to go directly to the PCM?
Thank you in advance.
Have you gotten anywhere on this ?
