"timing advance" is in timing degree's
"knock retard" is a voltage value NOT in degree's
for example if timing is 27 - 28 and knock retard is 6, that doesnt mean that it pulled 6 degree's of timing because of knock correct?? it just means that the sensor has senced some engine noise but not enough to pull timing, i guess what im wondering is what is the threshold for the pcm to pull timing down, in respect of the value of "knock retard"
I believe KR is used to measure the number of degrees of overall timing advance that needs to be removed to prevent detonation from continuing, which will protect the engine from dying.
