Im going to replace my Knock Sensor because my Scan tool says i have 3954 Counts!!!! It has increased because last time i check about 3 weeks ago it was 3606. Im wondering how do i Reset the pcm so that it relearns the modifications i have made. Raiss intake, spintech exhaust, 3.73 gears. This isnt as simple as clear codes, is it? Whats the best way to completely reset the PCM/ECU?
