2020 ram 1500 speedometer calibration
Here are the ways to get your car's speedometer out of calibration:
1. The actual vehicle speed is slow, but the stopwatch is fast. I measured it with a high-speed monitoring radar. My stopwatch 100 measured only about 94. As far as I know, most cars are not too accurate;
2. Causes, tires (old and new wear, size), factory calibration (there is an allowable error when leaving the factory) and other problems;
3. The diagnostic instrument can only detect whether the work is normal, and some problems cannot be diagnosed. For your own car, you can find out by yourself, as long as you know the difference, this is not easy to deal with, it can only reduce the difference, which is meaningless.
The reading of the speedometer indication is inaccurate, and when there is an obvious error in the mileage, it may also be due to the loosening of the flange lock nut, which may cause the original compressed odometer flexible shaft driving gear to loosen and slip. The driving gear of the flexible shaft of the 1090E automobile odometer is fixed by the locking nut on the flange of the hand brake drum, and is integrated with the second shaft of the transmission. The nut is self-locking by the deformation of four butterfly washers pressed inside it.
Generally, it is necessary to go to the repair shop for adjustment. The driver cannot accurately control the speed of the vehicle, which may cause traffic accidents! For novices, it is difficult to control the timing of shifting, which will damage the engine. There will be an electronic ticket for speeding or low speed on the road with a restricted sign, and you will not be able to pass the annual inspection.
But if If the wheels and tires are modified, there is no way to adjust the speed table. Tires are the only parts in the car that are in contact with the ground. Tires are very important for driving stability and driving safety factor. The size of the tire is written on the side of the tire. For example, 205/5-16, this represents the width of the tire 205 mm and the flat ratio is 55. The specifications and size cannot be easily changed, otherwise the driving stability and handling of the car will be related to the driving stability and handling of the car. The tire is a rubber product. The use of rubber products for a long time will be aging. Of course, it is advocated that riders will replace their tires regularly. When buying tires, you must also be optimistic about the production date. The tire is a rubber product. Even if you put it for a long time, there will be aging. The production date of the tire is written on the side of the tire. Produced from weekly. If the tires have been more than three years, it is advocated that riders must not buy it. After replacing the tires, make a new dynamic balance.
