Wheel Pulses and Circumferences
Calculations for the VSS Pulse Amplifier
You must supply a value for the wheel circumference that you
obtain from one of the following calculations:
If you know the number of pulses generated for one mile
(US version only):
63360
÷ pulses per mile = wheel circumference
(Set the number of pulses per rev to 1.)
Note: If the resulting circumference is less than 20.0
inches, double this value and set the number of pulses per
rev to 2. This is to make the calculated speed and distance
as accurate as possible.
Example:
Pulses per mile: 5000
Circumference = 63360
÷ 5000 = 12.67 inches
Double the two values:
Wheel Cir (ins) = 25.3 inches
W.S. Pulses/Rev = 2
Configuring the Fuel Pressure Sensor
(optional)
This sensor is highly accurate and it is no longer physically
required to change sensors for high or low fuel pressure.
