– The mileage calculation algorithms are closed‑source and developed by dashboard manufacturers. TachoSoft’s approximations can occasionally be off by ±250 km. As one seller notes: “As a rule, the mileage calculation algorithm is secret (closed) information of panel manufacturers, and the algorithms used in the program can sometimes be mistaken for + − 250 km.”
Technically, the use of Tachosoft 23.1 requires a high degree of competency. It is not merely a "plug-and-play" solution for the average driver. Effective use generally requires external hardware, such as a serial programmer or a dedicated OBD interface, to communicate with the vehicle's EEPROM (Electrically Erasable Programmable Read-Only Memory). The user must know how to locate the correct memory location, read the "dump" (the raw data), and identify the specific byte strings that correspond to the mileage. A mistake in this process can render a dashboard inoperable, highlighting that while the software simplifies the calculation, the risk lies in the execution. tachosoft mileage calculator 23.1
