  32  * @brief For evenly spaced teeth on the camshaft with a single second input.
  33  *
  34  * This is suitable for engines such as the GM DIS Wasted Spark Ignition engines
  35  * with 3x TACH output which would equal 3 teeth on the crank
  36  * and equal for something with 6 on the cam. Sync is provided by the second
  37  * input from the CAM 1x sensor allowing a sequential and/or COP/CNP setup to be used.
