Tachosoft 23.1 is not a hardware programmer; it does not plug directly into a vehicle's OBD2 port or chip. Instead, it acts as the computational brain in a multi-step repair process. Step 1: Chip Desoldering and Reading
Vehicle manufacturers treat odometer algorithms as proprietary, secret information. Tachosoft’s algorithms are reverse‑engineered approximations, and they may not always be perfectly accurate. The software itself acknowledges that in some cases. This discrepancy is usually acceptable for routine dashboard repair, but it is important to compare the calculated data with the original dump before writing to the chip. tachosoft mileage calculator 23.1
