We use this lead in-house at MJ Modifications and it has been faultless. Customers consistently praise the rock solid connection, quick communication and hassle free setup. If you want a proven interface lead for your BMW or VAG setup, this is the one enthusiasts and professional tuners trust.

Key benefits

• Original BMS interface lead for JB and JB4 controllers across BMW and VAG applications
• Secure wired link for log files, tune adjustments, firmware updates and map file transfers
• Purpose built chipset for JB units - not a generic USB adapter
• Plug in and go with flexible routing to suit temporary or permanent installs
• Ideal for enthusiasts who want dependable logging and quick desktop connectivity

Install and routing tips

For occasional use, the lead can be left in the engine bay and temporarily passed through a window or door seal when needed. For a neat, always ready solution, route behind the ECU into the glovebox for clean access to your laptop. Need extra length for through-door use? Add the optional extension lead for additional reach and to reduce strain on the connector.

Important compatibility and safety note

Use only this official BMS interface lead with JB and JB4 controllers. Generic RS232 or off the shelf USB adapters will not communicate correctly and may damage the control unit processor. Software, map files and instructions are available at n54tech.com.

Vehicle coverage

Works with JB series controllers fitted to BMW and VAG vehicles including Audi, Volkswagen, SEAT and Škoda when equipped with a compatible JB4 kit.
