Edge(s) For Sensor
The setting is typically "rising". "Both edges" results in (2x) higher reading but only works with very precise signal with exactly 50% duty (not needed for any known setup; might be dropped in future)

"Sensor signal min length" (speed_min_time, 64 usec resolution)
0: disables filtering. NonZero: pulses closer than this (64-16320 usec) are dropped (considered noise).

Speed Sensor Calibration
Enter the frequency of your sensor at 100 km/h (or 100 mph if mph reading is desired). 0: disable speed input (after reenable+burn: reboot ECU to start sensing).

Speed Sensor divider
Divide the sensor frequency by this value.

Example:
Edge(s) For Sensor = rising
k = number of wheel sensor pulses per rotation
f = frequency of the sensor
d = wheel diameter
v = velocity of the car

d*pi*f/k = v
f = k*v/(d*pi)

v= 100km/h = 27.77m/s (alternatively for 100 mph: 44.7 m/s)
d= 0.6m
k= 10
f=147.3Hz
then frequency of your sensor at 100 km/h = 147Hz

Second wheelspeed sensor calibration = 1 is special: wheelspeed2 pulses will be used for sectrig position measurement. Useful for subaru 4 trigger system. DO NOT configure 2nd wheelspeed sensor calibration = 1 if not having 4th trigger sensor. Value=0 to disable, or actual calibration (2-255) if using 2nd wheelspeed input as wheelspeed input (frequency measurement).

Gear Detection Settings (based on first speed sensor)
Enter your speed for each gear at 5000 rpm.
If Shiftcut input is chosen for drum position sensor, each gear is defined by voltage for each gear, and shift cut thresholds is based on the difference from these voltages. The table for this is found under Motorsports menu.
