One of the most important monitors for knock is called "Ign Corr. Cyl1". This along with the other cylinder monitors are going to tell you exactly what is occurring in the combustion chambers. The values here are degrees of correction applied to each cylinder based on the knock sensor readings. A positive value indicates additional timing added to the base ignition timing. A negative value indicates the removal of timing from the base calculation. Timing being added in logs is fantastic. This means the knock sensors are happy and are increasing timing based on the octane in your tank and lack of noise during combustion.
The best monitors to use on a V3: Boost, AFR, Ign Corr Cyl 1, Load Actual, CAT, Oil Temp
