Why the 4400rpm limit?

The knock detection code in the ECU can detect knock between 1200 and 4400rpm. The benefits to increasing the knock zone really depend on how you want your tune to behave, although the obvious advantage would be the additional safety factor.

Yes, I attached just a single wire. 2-wire set up = overkill
