TachoSoft Mileage Calculator is a specialized software tool used by automotive professionals to calculate and locate hexadecimal mileage data within a vehicle's digital odometer memory. While version 23.1 is currently the most widely documented stable release, unofficial mentions of version 25.9 exist in various online repositories. Core Functionality
The software acts as a lookup and conversion tool rather than a direct hardware programmer.
Database Support: Version 23.1 supports over 2,500 vehicle models including brands like BMW, Audi, Toyota, and Porsche.
Data Translation: It translates a physical mileage value (e.g., 50,000 km) into the specific hexadecimal strings required by the vehicle's EEPROM or ECM.
Address Mapping: It provides the exact memory address (e.g., lines 0000 or 0010) where the mileage bytes are stored. How to Use TachoSoft
To use this software effectively, you must first extract the vehicle's digital memory file (dump file) using external hardware like an EEPROM programmer.
Launch the App: Run the executable (often Tacho231.exe) as an Administrator.
Select Vehicle: Click "Select car" and choose the exact Make, Model, and Year from the dropdown menu.
Input Value: Enter the desired mileage in the "Odometer value" field.
Calculate: Press the "Calculate" button to generate the hex code.
Modify Dump: Manually edit your vehicle's .BIN dump file with the generated hex bytes at the specified memory addresses before flashing it back to the vehicle. Download and Safety Considerations TachoSoft Mileage Calculator Software 23.1 User Manual
