hooked it up to my friends matco scanner and reved it up so it was bouncing off the limiter and it showed 0.0 for KR. I asked him if it could just not be reading it corectly and he said if it wasn't getting a signal it would say "No Data" or N/A. So apparently I have no KR. The scanner is a Matco Dominator(I think) so its not cheap crap...
