Knock sensor issue

97 LT1 m6, I'm getting super high knock readings causing my spark readings to be all over. I've replaced the knock sensor and traced the wire back to the ecm and it checks ok. The knock readings are constant and do not fluctuate, picks one really high number and stays there until its started again.
