I was datalogging my 2011 Ford Mustang GT with the SCT X4 device and livelink, this is the Stock PCM tune, and on two different data logs I got huge spikes in the knock sensor reading a max value of 1238.25 and measured afr bank 2 reading a max of 46.50 (at a different time of knock "glitch").



I used Forscan and it has two PIDs for the Knock 1 and Knock 2 sensor, and I do notice one sensor is about a value of 100 always higher than the other one. Forscan shows Knock in values of 0 to 3000 instead of degrees, so not sure what the Forscan values actually mean.



Are these events a wideband sensor and knock sensor going on the way out, wiring issue, etc, or a glitch with SCT datalogging device?





Thank you
