Hi Derek, Ford refer to flash files as calibration files, so maybe that could be where the "calibration" came from. I would be amazed if it was running lean enough to have the rear sensor switching and be cured by a flash. Did you check the gasses before and/or after you condemed the cat? Did you check the O2 sensor signals after you fitted the cat? Another odd thing is why it didnt set a P0420? Alan
