I don't know what it is but you could calculate it to get started and then adjust it for real world later if it is not close enough.
A guess on how to calculate it (having never done so before)
1 Lift rear tire off ground
2 Remove speed sensor from transmission
3 Rotate rear tire until tire valve stem is on bottom to use for reference point
4 Rotate tire one full revolution and count the number of teeth that pass where the speed sensor would have been
5 Measure the circumference of the tire
5280 feet/mile divided by the circumference measurement = tire revolutions/mile
Then tire revolutions/mile multiplied by the number of teeth per tire revolution should equal the approximate number of pulse per mile from the speed sensor.
Sounds complicated but really should only take a few minutes to accomplish.
This is just a guess but it is where I would start if I could not find the information needed.

Thanks Airglider- Assuming the frequency in the table is cycles/second, I figure it's running 84000 pulses/mile. Unfortunately my cruise only has settings up to 38000, so it looks like I'll be using a magnetic pickup instead of the VSS.
