Re: [DML] Re: "1980's Delorean Speedo Cable Fix"

That's because at 60 miles per hour, you do one mile per minute, and at 1000 revolutions per minute of the cable.... 

the numbers are tied to each other intrinsically, not deliberately

If the odometer is not calibrated and you cannot just change the gear which is usually what is done (on other cars, not Deloreans), you calculate how much and which way it is off and you buy a ratio unit that is installed between the cable and the head. As for calibrating the speedometer, all it usually takes is bending the tab that anchors the spring after cleaning and relubricating the head. The choice of spring determines the linearity of the accuracy curve (that affects the accuracy at the ends of the scale, ie, low and high speeds, it should still be right on at 60 MPH). Not only is the speedometer supposed to read 60 MPH at 1,000 RPM's of the cable, the cable is supposed to rotate 1,000 times over the course of a mile. They use these #'s to keep the math easy. I do not know what it is in Metric, you can do the conversion.
