Also I fill up at any gas station. Hess, Bp, sans club. Etc.
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.
It's not important to win, it's important to make the other guy lose.
