NO ALARMS if left plugged in (BMW G series vehicles and Toyota Supra)
- Enters ultra-low power mode if left plugged in consuming just ~20mA
OTA updates through the new bootmod3 app
Firmware fully extensible for additional flash and diagnostic protocols for future connectivity support
Manual Toggle switch to fully power down the adapter
Small form factor, considerably smaller than generic WiFi ENET adapters
No VIN locking, can be used on multiple vehicles

The JB4 features a simple plug & play installation harness for easy installation & removal and includes many features not found with any other tune. Including on the fly in-dash map switching between factory and various performance maps, optional in-dash gauge displays for boost, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built-in data logging, built-in code reading, optional direct EWG control to prevent throttle closure with exhaust modifications, exhaust flapper control, and much more. Other more expensive tuners may claim to equal the JB4's technology but upon closer examination lack most if not all of the JB4's features.

JB4 takes your F95/F96 BMW X5M/X6M from factory stock to full race-ready performance, offering unmatched tuning capabilities. Designed for easy installation and complete removability, the JB4 requires no splicing or cutting of factory wires, making it the ideal choice for your S68 engine. The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections, making your vehicle much faster. While it's not the only tuning system that operates this way, the JB4 separates itself from the competition with much more advanced connection points and processing, including CANbus, fuel & spark control, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates, adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated, the JB4 has been the gold standard in plug-and-play turbocharged performance tuning for over a decade.

JB4 takes your G90 BMW M5 from factory stock to full race-ready performance, offering unmatched tuning capabilities. Designed for easy installation and complete removability, the JB4 requires no splicing or cutting of factory wires, making it the ideal choice for your S68 engine. The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections, making your vehicle much faster. While it's not the only tuning system that operates this way, the JB4 separates itself from the competition with much more advanced connection points and processing, including CANbus, fuel & spark control, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates, adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated, the JB4 has been the gold standard in plug-and-play turbocharged performance tuning for over a decade.
