The Real Problem: J1708 to J1939 Communication Gap
Some engine ECMs still communicate through J1708, while newer or replacement cabs require J1939. Without the correct conversion, the cab may not receive the data it needs—causing missing information, dashboard errors, or communication issues.

- ✔ Reads J1708 engine data
- ✔ Converts it to J1939 cab communication
- ✔ Supports 250 kbps or 500 kbps J1939 output
