Is that the electronic throttle sensors?

Why would they? What does it do?

Makes 'em easier to pull over. Releases a little compression so they're easier to crank, then restores full compression once it's running.

Cats don't have DET. That is a Polaris system for detecting detonation. It uses a knock sensor on the bottom side of the head to sense pinging in the engine. It will retard the timing until the detonation stops to keep from melting down pistons.
