Many universal MAIMEIMI models are designed primarily for carburetor engines. While basic functions like speed may work, specific features like RPM display may not function correctly with Electronic Fuel Injection (EFI) systems unless the specific model supports it.
Most MAIMEIMI digital units allow you to enter the setup menu and adjust the wheel circumference parameter. This ensures the speedometer and odometer remain accurate if you change wheel sizes.
For OBD2 mode, the working voltage is typically 11V~18V DC. If your vehicle uses a higher voltage (e.g., >24V), you should usually switch to GPS mode and use a USB cable connection.
In GPS mode, satellite drift can cause minor speed readings (e.g., 1-5 km/h) when stationary, especially in tunnels or garages. This typically resolves once you drive on an open road with a strong satellite signal.
