BMS BMW & VAG JB4 Bluetooth Connect Kit - Unpinned Version, Older JB4 Units (Rev. 3.7)

Wireless smartphone control for Burger Motorsports piggyback tuners - external power lead version, Revision 3.7

Unlock hassle-free, cable-free access to your tuning box with the Burger Motorsports wireless link module. This Revision 3.7 Bluetooth 4.0 LE adaptor lets your iPhone or Android device talk directly to your piggyback controller in the engine bay, so you can view live parameters, record logs, switch maps, read and clear fault codes, adjust user settings including meth control, and flash the latest firmware all from your handset. No need to route a data cable through the cabin - tidy, fast and reliable.

This listing is for the external power wire configuration designed for legacy controllers with the square case and earlier board designs. It is the correct option for BMW N54 systems and any unit produced prior to 2017 that requires a separate power lead. Later boards typically use the pinned power version - if that is what you need, choose the alternative pinned kit.

Why enthusiasts choose this module

• Instant Bluetooth link to your tuning box for real-time gauges and on-the-fly map changes
• Datalogging made easy - capture, graph and share performance runs straight from your phone
• Fault code read and clear functionality for quick diagnostics
• In-app firmware updates to keep your controller current
• Customisable gauge layouts and themes for a tailored dashboard experience
• Mounts beside the control unit in the bay for a clean, stealthy install with minimal wiring
• iOS and Android compatible - app available separately on the Apple App Store and Google Play
• Made in the USA by Burger Motorsports

Compatibility

Works with Burger piggyback tuning systems including JB4 and JB1. This specific kit suits earlier controllers that require an external red or blue power lead and use the square enclosure. If your hardware is a newer design with a pinned power arrangement, select the pinned power variant instead.

Good to know

• Bluetooth 4.0 Low Energy connection for a stable wireless link
• Adapter connects to the controller at the data port, with separate power and ground to the harness using the supplied connectors
• Not compatible with the Windows PC interface
• JB4 Mobile app is required and sold separately

Installation and fitting support

Fitting is straightforward: mount the module next to the tuning box in the engine bay, plug into the data connection, then attach power and ground to the harness with the included terminals.
