Why does the speedometer read how many revolutions?
Your speedometer is reading how many revolutions your tires are making not how fast they are spinning. When you go to bigger tires the circumference of the tires is larger, meaning the distance around the tire is longer. Thus, with each revolution you are traveling further than before.
Where is the speedometer on a S2000?
The first thing we need to do for the install is lift the front of the car up onto jack stands. The speed sensor for the speedometer is on the transmission for the S2000, so we’ll need access to it. Once underneath the car, unplug the sensor from the transmission, and plug in the new harness.
What should the speedometer be at at 80 miles per hour?

Why does the speedometer read higher with bigger tires?

When did the Ranger stop using a speedometer?
In 1995 the Ranger stopped using a mechanical speedometer cable and relied on the VSS in the transmission/transfer case to provide it with a signal for speed. The 1998-2000 Rangers are not equipped with a VSS (Vehicle Speed Sensor).
Why is the speedometer still a mechanical unit?
The computer uses the VSS signal for emissions control programs and speed limiters. The emissions programming can cause a manual transmission vehicle to stall out while decelerating if no VSS is used. The speedometer was still a mechanical unit because the VSS still turned a cable going to the speedometer.
How do you disengage the cable on a speedometer?
