In the right edit box you enter the pulses per mile the speed sensor produces. Speed sensors are
typically pulse sensors mounted either on the drive-shaft or wheel. To calculate the pulses per
mile (or km/h) click on the calculate button:
Select if you use a drive-shaft sensor or a wheel sensor. Enter the pulses per rotation created by
the sensor either as driveshaft rotation or wheel rotation. You also need to enter the wheel
diameter, and in case of a drive-shaft sensor, the final drive (differential) ratio.
The LM-Programmer will calculate the pulses per mile (km) for you.
This functionality is also available for Inputs 4 and 5.
