your best bet is to ignore your standard knock sensor, as 9/10 are buggered

There are also too many other factors that cannot affect the knock sensor i.e. exhaust, something loose or rattling etc etc....
 
Although saying that i dont see anything more than 40 on WOT but i\'ve also seen 164 for some reason and that was idling so who knows....

The standard knock sensor on anything other than a bone standard car is completely useless and Ive turned my warning function off on the commander.
 
I had a thread last month about this very thing and the above is pretty much what pip said.
 
Have a look: search "heat light flashing"
