How do you have it turned off?
I wondered about that myself, when i started reading about what they are and how they work. Then listening to sound clips i must say it sounded a little iffy to me. I then read where some one said they use some kind of audio filtering or somthing to single out the knock. It makes a little more sence till the OP said they are only $30. for the sensor now im starting to wonder.
If i raced my car i dont think ide want one pulling timming out but for how im using my car ill leave it alone.
