I've heard that you can add some kind of resister or do some kind of modification to convert kh/m to mph with the jdm clusters. Rumor or Fact?

I would like to use a jdm cluster but hate reading kh/m. I guess i can get use to it, but rather have it in mph.. Can anyone state that this subject is true or false..

bump if you would like to know also..

 

Doesn't it depend on what year/model?

Some speedometers are driven directly from a pulsed signal (VSS). A resistor won't change the pulse timing. Sometimes the VSS is wired only to the ECU, and the ECU drives the speedometer. In that case I have no idea what the signal looks like. Maybe you can use an oscilloscope to watch it?

You'd probably have more luck making some kind of graphics overlay that you can stick over the dial. Like indiglo gauge faces or something like that...
