Overspeeding, whether knowingly or unknowingly plays a major role in fatal accidents on US roads. In 2017 alone, we lost more than 1,900 lives due to overspeeding. Some drivers get involved in accidents even when driving on legal maximum speed limits.
How does this happen? Well, sometimes, your speedometer can display wrong values, especially if you have an old car.
You can also experience a speedometer calibration error if you use after-market tires. This means that the wheel’s diameter may be greater than the stock wheel.
That’s where a speedometer calibration service near me comes in. But is it really worth it? What’s the most effective speedometer calibration tool?
How do you find the best speedometer calibration near me? Find out more on this guide.
Different Types of Speedometers
Generally, we have two types of speedometers, depending on the system’s mechanism. They include electric and mechanical. However, the main causes of speedometer errors, whether electric or mechanical are the same as highlighted above.
Electrical speedometers are prevalent in modern cars that come with a computerized ECU. The ECU controls the speedometer by measuring transmission pulses generated by the output shaft.
On the other hand, mechanical speedometers are prevalent in older car models produced in the 80s and 90s. This speedometer uses a cable that runs from the gear to the transmission, creating a magnetic field. The magnetic field pulls the speedometer’s dial to show the car’s speed.
How to Test Your Speedometer
It will help if you test your system before researching speedometer calibration near me. This way, you’ll tell whether the speedometer is faulty.
How do you test it? You’ll need to measure a certain mile covered and compare it against your odometer’s reading. It’s easier to estimate this using the mile markers found on nearly all interstate roads. You can also find mile markers on select county roads.
Before beginning on your first-mile mark, reset the odometer to 0.00. Then, drive to the next mile mark and check if the odometer’s reading shows the exact mile covered. If there is a variation, then your speedometer shows a faulty reading.
How to Calibrate Speedometer
The best speedometer calibration tool is a dynamometer. Typically, a dynamometer measures torque and rotational velocity. This tool can help you determine the actual speed displayed by the speedometer with respect to tire rotation speeds.
It’s worth noting that speedometer calibration can help you during court trials. If the prosecution charges you with overspeeding, you can prove that your car moves at a different speed from what the speedometer displays.
How to Find the Best Speedometer Calibration Service Near Me
What makes “the best speedometer calibration service near me?” How do you find one? You’ll need to conduct thorough research on automotive shops around your location. After that, ensure that the shop has the right chassis dynamometer.
The technician will use the chassis dynamometer to note different speedometer readings on each tested speed. Then, the technician will record these values in a speedometer calibration certificate.
