Feature request: Scaling on pulse/RPM signals

[GTIspirit]

Could we get a scaling factor on the pulse/RPM signals?

My 1987 VW GTI has a handy wheel speed input for the onboard trip computer, one tick per kph, basically, 1Hz=1kph. Except my tires are slightly bigger than stock, so a correction factor is needed to align the wheel speed with the GPS speed.....

I could imagine other uses for a scaling factor on pulse/rpm signals to take the sensor reading and turn it into a physical signal.
