Now I'm confused. The stock size tire turns 811 times per mile. The sensor is supposed to output 8 pulses per tire rev. 811*8=6488 pulses per mile.

Crosschecking that number, if the scope shows 11 pulses in 100 mS at 60mph, that's 110 pulses per second * 60 sec = 6600 pulses per minute (1 minute = 1 mile at 60 mph). So 1 mile = 6600 pulses. Pretty close.

What am I missing?
