RaceCapturePro2 ShiftLights

Sequential Shift light

One way to enable shift light is by using the PWM / Analog output channels to trigger a 3 + 1 shift light output. In this case, we used 3 of the outputs to control the 3 LED segments on the ShiftX Sequential Shift Light display, and the 4th output controls a focused Red LED that flashes at the top end of the RPM range.

Requirements

  • A working RPM signal connected to the first timer input channel on RaceCapture/Pro.
  • Shift light boards connected to PWM / Analog out 1 - 3; flash alert LED to the 4th output
