good afternoon, how is everything going? I have a doubt about an ecu with which I am investigating, recently acquired another a4 b5, this time awt engine, with ecu 4b0906018r which seems very rare compared to other me7.5 wideband with vvt module, my question is Could I replace the software of this ecu with that of a 032 HJ or any other me.5.5.5 wideband? Would there be some kind of problem? What are you pinning? greetings from Spain
