Speedo

Will a 120 MPH police package speedo work in place of the std 85 MPH unit? Or will I need to swap the sensor/ecu? Not that I ever plan to actually hit 120, I like the 1 MPH increments on the PP unit.

I remember this subject about 6 months ago. Try a search and see what you can find. As I remember it, the best solution seemed to be to get a new speedo face (paper or plastic that attaches to the front of your stock speedometer) and a new speedo gear (that attaches to the transmission) for this to work. If I remember correctly, GoJeep was one of the people who recommended this course of action. This might, however, cause your odometer to read incorrectly.
