Before understanding the calculator, one must understand the hardware. Modern vehicles do not use mechanical odometers with rolling gears; instead, they use a digital odometer displayed on the instrument cluster. The mileage value is stored in an EEPROM chip—a non-volatile memory device that retains data even when the car’s power is off. This chip is soldered onto the circuit board of the instrument cluster and often contains other vehicle-specific data, such as the Vehicle Identification Number (VIN) and service intervals. eeprom mileage calculator online
