Version 23.1 is known to contain data lines for over 2,000 vehicle models, primarily covering cars, motorcycles, and commercial vehicles manufactured between the late 1990s and the early 2010s. Because Tachosoft has not received official updates in many years, it does not support modern vehicles that use encrypted gateways, secure microcontrollers, or synchronized mileage data across multiple modules (such as the ECU, BCM, and keys).

Cracked software is frequently modified by amateur programmers. These modifications can corrupt the core calculation algorithms of the tool. If Tachosoft generates incorrect hex values due to corrupted software, writing that bad data to a vehicle's EEPROM can permanently corrupt ("brick") the instrument cluster, requiring expensive hardware replacements. 3.
