As for knocking a lil here and there at partial thottle, it is just as important as wot imo....especial when you change the air flow characteristics of a car and run it on the stock tune plus some timing. I am not saying Shivs tune is knocking partial throttle all the time. I am say the stock tune knocks here and there, adding timing to that is not something i would personally do, hence the reason i asked him to check it out in his spare time.
Yes the engine COULD knock a very small rate even in partial throttle. But it depends on how severely that knock is per EF.

Every engine is different in regards to what is considered "safe" knock. For example, on a given motor, 60 ms of knock per EF is unsafe. Where as the engine could have knock a few times at around 15-25 ms per EF in part throttle.

However, this is Shiv's thread and I think you wanted the response from him, not me, so I will let him answer you if he chooses to.
