Can the additional LCD speed indicator show speed in mph rather than kmph?
For high accuracy of speed indications it is desirable to adjust the speed display to take into account different rim/tyre combinations fitted to the car. Wheels of a larger rolling diameter cause the speed indications to under-read and smaller sized wheels cause it to over-read. The delimiter with LCD speed display has a provision for fine adjustment of the road speed sensor signal. In fact, the internal adjustment circuit in the delimiter was designed in such a way that it is possible to enter a correction constant high enough to achieve speed indications in mph (or even knots) rather than kilometers per hour. Our customers in UK and Ireland may find this function useful.
