Knock Knock Knock
 

Hi guys,

I understand what knock is, but I've no idea on how it is measured and what is considered to be a dangerous level.

I've got a Power Fc and so on the commander it rates the knock digitally. I've had mine up to 17 before, but I've not idea if thats a safe level or not.

Can someone explain it for me?

mine regulary reads 28 when driving enthusiasticaly,read somewhere that they are not very accurate but over 50 is BAD NEWS :)
