Whats This Part?

what sort of engine ecu are you going to use adam? you might not even need it. even with nistune some tuners will just copy the normal maps to the knock maps so knock detection is pointless.

Most tuners SHOULD copy fuel maps from the main maps to the knock maps, and then pull some timing across the board AND make the knock map a little richer in the knock maps.

You can run without them, just a resister in the line to ground to stop switchuing maps and logging fault codes, but no safety backup then.

Price is ridiculous, just get one from a wrecked car.
