In older cars, mileage was stored exclusively in the instrument cluster chip. Modern cars store mileage synchronously across multiple Electronic Control Units (ECUs), such as the Engine Control Module (ECM), Body Control Module (BCM), Transmission Control Unit (TCU), and even the electronic ignition switch (like Mercedes EZS/EIS). Manually altering just the dashboard hex code via TachoSoft will result in the dashboard immediately pulling the old, higher mileage from other synchronized modules, or throwing a data mismatch fault code (DTC).

At its core, Tachosoft Mileage Calculator is a Windows-based utility for instrument cluster repair and module replacement. Its primary function is to calculate the correct , allowing technicians to synchronize odometer data across dashboards and CAS-type units without guesswork. In simple terms, when replacing a car's instrument cluster, its internal memory (EEPROM) still holds the old mileage. The software helps a technician locate the specific memory addresses where the mileage value is stored and calculate the correct hex codes needed to enter a new value. In older cars, mileage was stored exclusively in
