Title: Knock Tables?
Post by: IWay on August 12, 2020, 04:10:28 AM
Is there such thing a knock tables for engines?

IE

At a given octane, AFR & IAT a knock plot could be produced of RPM V boost = no knock or knock, see attachment for example of what I'm asking.

like wise you could use any of the values as the constants and the remaining values as the X & Y axis of the graph.

Thanks

No.

That isn't even remotely how knock detection works, which, incidentally, is covered in depth in the various FRs.

There is literally no way to build a table like this, since knock itself doesn't work like anything you described. There are at least a half a dozen or more things that influence knock just as much (or more) than boost or rpm.

Cheers,

I thought that would be the answer or else I expect I would have found such a thing by now.

Just wanted to make sure.
