"Couple questions about the LT4 km. I was under the impression it was simply a "less-sensitive" sensor. Instead of say an entirely different sensor with a different frequency range it listened for. Is this correct? If so, I like the idea of keeping my sensitive stock piece in place; at least until I get a proper tune on the car."
The #16214681 LT4 module is just a different filter for the output of the knock sensor that the GM engineers designed for the LT4 engine version with it's roller rockers and less restrictive exhaust. It takes into account the effect that roller rockers contribute/transmit to what the knock sensor (contact mic) picks up. It was $28.75 through Jason Cromer ... almost 5 years ago(!)
