TachoSoft Mileage Calculator 23.1 is a digital tool used for calculating odometer hex codes for thousands of vehicle models. It is primarily used by technicians to recalibrate dashboards after repairs or replacements. Important Disclaimer
The software functions by calculating how mileage is stored in a car's EEPROM or ECU so you know which specific bytes to edit using a separate programmer tool. Select Vehicle : Click the "Select car"
The TachoSoft Mileage Calculator 231 is more than just software—it is a testament to the reverse engineering community’s ability to decode automotive secrets. Treat it with respect, learn the hex fundamentals, and it will serve you for years to come.
With the rise of encrypted CAN bus and digital odometers stored in microcontroller flash (not EEPROM), tools like TachoSoft are evolving. Version 231 may be the last of its kind to focus on discrete EEPROM chips. New vehicles (Tesla, BMW iDrive 8, Mercedes MBUX) store mileage in secure elements requiring OEM-level access.
Checksum Recalculation: This is the true test. If you change the mileage (e.g., after replacing a faulty cluster), the car’s CPU will check a mathematical signature. If the signature doesn’t match, it will reject the change or light the odometer with “ERROR.” Tachosoft 231 recalculates the CRC-16, XOR, or custom manufacturer checksum in real time.

Price Range: Expect to pay between €40 and €80 for a personal license. Commercial licenses with update support cost more.
One of the biggest headaches in odometer correction is the "Check Engine Light" or "Dash Error" caused by a mismatched checksum. Tachosoft Mileage Calculator 231 includes an automatic checksum fixer for most protocols. If the original data has a corrupted CRC (Cyclic Redundancy Check), Version 231 is particularly adept at rebuilding the file without bricking the cluster.
Dispatchers can enter up to 231 waypoints (likely the origin of the version number in some editions). This allows for complex routing with multiple pickups and deliveries, calculating total trip mileage, leg-by-leg breakdowns, and cumulative fuel estimates.
