The software works by reading the EEPROM memory chip (usually 93Cx6, 24Cxx, or 95xxx series) from the cluster, calculating where the mileage data is stored, and allowing the user to write a new, accurate value.
Version 231 likely refers to a specific release or build number—many online forums mention “231” as a stable version popular among hobbyists and professionals before later updates introduced more anti-piracy protections.
In the world of automotive electronics and diagnostic tools, few names generate as much discussion—and controversy—as TachoSoft. The software is widely known for its ability to calculate and adjust digital odometer values by reading and modifying EEPROM chips from vehicle instrument clusters. Among the most searched variants is the TachoSoft Mileage Calculator 231, often accompanied by enticing but risky phrases like “free download,” “top quality,” and “extra quality.”

TachoSoft Mileage Calculator 23.1 is a widely recognized digital odometer calculation tool used by automotive professionals and DIY enthusiasts to identify and modify mileage data within a vehicle's EEPROM/ECM files. Core Features and Capabilities
Broad Vehicle Support: Version 23.1 covers between 2,000 and 2,500 car models, including major European (Audi, BMW, Mercedes), Asian (Honda, Toyota, Nissan), and American (Ford, Dodge, Jeep) brands. Use free & legal alternatives
Data Identification: Unlike basic tools, it provides the exact hexadecimal location (offsets) where mileage is stored in a computer program, allowing users to manually edit the values for precise correction.
User Interface: Designed with a straightforward interface, it allows users to select a car brand and model to instantly see the algorithm needed for that specific odometer.
Portable Operation: Some versions are portable, meaning they can run directly from a folder without a full system installation. Download and Installation Information
The "free" or "top extra quality" versions found online are often shared via community forums or third-party marketplaces.
Sourcing: You can find the software through specialized automotive diagnostic sites like ELM327Rus (often password-protected) or CarSoftos.
Antivirus Precautions: Most installation guides explicitly state that antivirus software must be disabled before downloading or extracting, as these tools are frequently flagged as "false positives" due to their nature.
Format: Typically delivered as a compressed .zip or .rar archive containing the Tacho231.exe executable. Critical Usage Notes
Professional Requirement: This is a specialized tool that requires knowledge of EEPROM/ECM data manipulation. It is highly recommended to test on a spare chip before working on a customer's vehicle.
Hardware Needed: The software alone cannot change mileage; you typically need a separate EEPROM programmer (like UPA-USB or XPROG) to read the vehicle's chip and save the data as a .bin file for TachoSoft to process.
Legal Warning: Tampering with odometer readings to deceive buyers is illegal in many jurisdictions. The software should only be used for legitimate repairs, such as replacing a faulty instrument cluster. Check for a trial/demo

Safety Protocols: Licensed versions include checksum generation to prevent system errors or permanent cluster damage. OS Support: Compatible with Windows 7, 10, and 11. Availability & Download Risks
While some sites like Scribd or unofficial Google Drive links claim to offer free downloads, these files often carry significant risks:
Malware: Many unofficial "free" versions require you to disable anti-virus software during installation, which is a high security risk.
Fraud: Counterfeit versions often lack safety features like checksum alignment, which can break a vehicle's instrument cluster permanently.
Official Sources: Authorized versions are generally purchased through automotive diagnostic retailers like VXDAS or specialized AliExpress automotive stores. Legal & Ethical Considerations
