I just installed the Ultimate, I also have the Airflow input 1 not detected error. Did you get the issues worked out and tuned. I have tried the HN-pr1 and the SD-pr1, both with no help. Did your car run stupid rich on start-up (9.3-10.5) with a crappy idle for a few seconds then smooth out yet stay rich.
