I am using 8204 for my pulses/mile. On my trip back from Savannah today, it was very jumpy for a few miles (reading generally higher than speedometer reading). After that, it was almost dead on and never varied more than half a m.p.h. off of the speedometer reading. I'm starting to think loose wire, or the connection I made to the car doesn't like the rougher ride my car gives it. I'll give it a little longer and compare the numbers. The distance is almost right on according the odometer, so it's getting all the pulses, I believe.
