How does Cheya measure 0-100 km/h acceleration?

For automatic transmission vehicles, press the brake with your left foot and rev the engine with your right foot. When the RPM reaches around 3000, suddenly release the brake. At the same time, press the accelerator pedal fully until the car accelerates to 100 km/h. For manual transmission vehicles, first press the clutch with your left foot, engage first gear, and rev the engine with your right foot. When the RPM reaches around 3000, suddenly release the clutch. At the same time, press the accelerator pedal fully. When the engine RPM approaches the limit, shift to second gear while keeping the accelerator fully pressed.
I often use the CarVista to measure 0-100km/h acceleration, which is quite convenient. CarVista is a small device that plugs into the car's OBD port, usually located under the steering wheel. Open the mobile app to pair and connect, select the acceleration test function, find an open area or test track, and start the test with the car stationary. Press the accelerator fully to reach 100km/h, and the app automatically times and displays the result. During the test, I make sure to turn off the AC to reduce load, and since road conditions affect the results, I choose dry days and closed areas for testing. After recording the time, I share the data and analyze performance changes. This helps me monitor my car's condition regularly, especially after modifications to see if there's any improvement in acceleration—it's very practical.
Testing acceleration with CarVista is quite simple, and I've tried it several times. Plug the OBD device into the car, pair it with the mobile app via Bluetooth. Click the acceleration test button in the app, find a safe location like an empty parking lot, shift the car into D or S gear, then floor the accelerator to reach 100km/h. The app instantly calculates the time taken. During operation, I ensure strong GPS signals to minimize errors, and the app can also generate charts to display the acceleration curve. It's best to charge the device before testing and remember to reset the settings to avoid interference. The results are accurate and have helped me optimize my driving habits.
