How to modify car odometer data (how to modify car mileage)

1. Adjust the vehicle odometer There are European Cup livetwo ways: to disassemble the dashboard. Through OBD, the instrument adjustment equipment varies according to different models. Some watches can be adjusted directly through the OBD socket, and can be adjusted more or less.

Normal range of new energy vehicle RPM data

1. Generally speaking, the speed of the car is normal without entering the dangerous speed range, but pay attention to whether the speed of the car coincides with the current gear, otherwise low High-speed or low-speed high-speed transmission will cause damage to the vehicle.

2. NormalThe speed of this motor is about 4000rpm, and the speed of 60 kilometers is also the best state speed.

3. rpm may only be 50%. We all know that the turbocharged engine is powerful, and the maximum torque is in the maximum torque range of 1800-5000 rpm, which is the most powerful in this speed range. If it is less than 1800 rp./minute or more than 5000 r.m., it is weak. Generally speaking, torque is force and has nothing to do with speed.

4. In addition, the speed range under economic conditions is wider than that of the internal combustion engine, and 0-7000rpm is basically the normal working range.

5. When the car is running, if the pointer on the tachometer points to 1, it means that the engine speed is 1000 rpm, and if the pointer points to 2, it means that the engine speed is 2000 rpm.On some models, the tachometer is marked with 30. In fact, the speed of the car is the same, but the expression on the tamometer is different.
