MAIMEIMI support FAQ

Mafunso wamba okhudza zolemba, kulembetsa, ndi chithandizo chamtunduwu.

  • Will the MAIMEIMI universal speedometer work with EFI engines?

    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.

  • How do I calibrate my MAIMEIMI speedometer after changing tires?

    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.

  • What power supply do MAIMEIMI HUDs require?

    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.

  • Why does my HUD show speed when the car is stopped?

    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.
