CGDI Super Kilometer CAN Filter Mileage Correction Emulator

This device is a CAN‑bus emulator hardware module designed for use in vehicle mileage correction workflows. It acts as a mileage (odometer) signal filter/emulator on the car’s CAN network, allowing certain mileage correction tools (like programmers) to work without causing communication errors in newer vehicles’ systems.

• CAN Filter / Mileage Emulator: It intercepts or filters CAN bus signals related to mileage between the instrument cluster and other electronic control units. This can allow external programmers to modify or “mask” mileage data without causing fault codes or CAN errors.

• It’s not a standalone mileage reader — it doesn’t read or set odometer values by itself; rather, it supports mileage rewriting tools by stabilizing signals.
