The DL-1 logs the raw frequency in its .run file. RT Analysis computes RPM based on the pulses per revolution that the user enters in the Vehicle Data.
The Display-1 option is a little sparse. but it seems to be able to display RPM. There must be a way to load the #pulses into the Display-1, but I can't locate documentation on how & where that is done.
The G2X has a display to drive in real time, so it needs to know what factor to apply to the pulses in real time. Rather than ask the user to know the factor, the Gx2 user simply selects the number of cylinders, and the G2X then displays RPM.
