Knock sensor, REM+ data

[Wounded_Fighter]

Is there an acceptable amount of knock? I assume not, but if there is... How much knock is too much knock?

I'm looking at 94KNO @ 3600rpm (4th gear, speedo pegged on the needle... 85+) and roughly 20KNO @ 1500rpm, 0-4KNO @ idle

Wondering the same thing--I have "high" knock in my truck.  That document that Ohm shared shows between 10-100 at 2500 RPM.  Does that sound right and does it correlate to the reading from the REM?

Yep. Pretty much anything off idle and up you will see a knock value.
