ECU or Pcm reflash?
Hello everyone! I just got done installing a new air intake and long tube headers onto my A6 base. Now, as I expected, I have check engines codes for the upstream and downstream for the o2 sensors and the difference in flow through the catylitic converter. Does this get fixed by a PCM reflash? Or is there something else I have to get done? Thanks to anyone who responds.
