Ford B9B1 Calibration Knock Sensor Retard Rate Table (RPM vs Degrees/Event)

This document is a screenshot of a calibration table titled 'Knock Sensor Retard Rate,' apparently taken from engine tuning/calibration software. The table maps engine speed (rpm) to the ignition timing retard rate applied per knock event (degrees/event). Six rows of data are shown: at 8160 rpm the retard rate is 0.500 degrees per event; at 4800 rpm it is 1.000; at 3616 rpm it is 1.000; at 2816 rpm it is 1.500; at 1600 rpm it is 0.500; and at 0 rpm it is 0.500. From this a reader can learn how aggressively the PCM pulls ignition timing in response to detected knock across the rpm range — most aggressively (1.5 degrees per knock event) around 2816 rpm, and least aggressively (0.5 degrees per event) at very low rpm and near redline. The upload filename references calibration 'B9B1,' and a companion file in the same album covers the corresponding knock sensor advance (timing recovery) rate. The album context associates this with a 1993 Ford Taurus, likely the SHO given other album contents, though the image itself states no vehicle, year, or calibration ID.
