getting false knock wierd numbers

[QUIP'6']

i am running 20 psi 23/21 timing and alky on 7. when i nail it at 5 or so mph the car ramps up very quick and i get 14.1 degrees of knock 10.8 a/f then it goes away. why would it show 14.1 every time? is there something wrong with original knock sensor? thanks

Are the tires spinning? I get false knock all the time when the tires spin... if I get knock and no tire spin, I start looking for problems...

My tune was good, but I got false knock from a bad convertor.( took 2 summers to narrow it down) Same knock level at same RPM almost everytime.

Some tire spin maybe 5 foot or so.

Thanks will have to start checking things. Just thought it was wierd to get 14.1. 4 or 5 times in a row
