All the tune knock discussion had me looking into alternative ways of analyzing how tuners were tweaking the knock response loop and I came across VAGCOM blocks that log actual knock sensor voltage vs. timing pull.

Do you know if anyone has tried to log both the voltage and the timing pull so see how they are correlated for a given vendors tune.
Since “desensitizing” the knock sensors in application is reprogramming how the ECU responds to a given voltage value it would be really interesting to see at what voltages trigger how many degrees of pull under given conditions and compare that across OEM, GIAC, APR, REVO.
I thought that might be interesting, but I obviously have very little experience in this area so putting it out there to see if I am totally off base or if you guys had any thoughts or insights.
