Phantom Knock

[zachdeagle16]

When i log im having a hard time figuring out what is phantom knock and what is real knock lots of times im getting readings like 40 counts of knock at 4500 rpms and an 02 voltage of .75

Phantom knock is usually when you just start knocking for no reason....usually full throttle knock is real knock but not always. Or sometimes if you add or subtrack fuel and still you are pegging knock thats phantom knock. Its hard to explain it but you really have to kind of figure it out your self.
