Description
The Burger Tuning BMS S58 JB4 is an advanced plug and play tune designed specifically for 2020+ BMW M3/M4/X3M/X4M models. This powerful tuning system offers gains of up to 150whp/175wtq on higher octane or E85 mixtures, as well as up to 80whp/100wtq on pump gas. The JB4 offers a lot more performance, functionality, and safety than your average performance chip, making it the gold standard in plug and play turbocharged performance tuning for over a decade.
One of the most unique features of the JB4 is its advanced connection points and processing, including CANbus integration, fuel and spark control, and Bluetooth connectivity to your smartphone. With up to 8 preloaded maps for various fuel and modification levels, the JB4 allows you to go from factory stock to full race, and everywhere in between, with the push of a button on your steering wheel. The JB4 also includes many unique features not found in any other tune, such as user adjustable 1st and 2nd gear boost limiting, in-dash map switching, electronic wastegate control, and built-in advanced CANbus based diagnostic tools.
Installation of the JB4 is quick and easy, and the system includes the rugged JB4 billet aluminum enclosure for protection. The JB4 installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections, making your vehicle much faster. 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 be quickly removed and swapped between cars or resold at a later time.
The JB4 runs as smoothly as stock, and is compatible with all driving modes, with fuel economy unchanged during normal driving. The system is also able to read and delete fault codes, making it a valuable diagnostic tool. Ethanol (E85) compatible tuning maps are also available, and the JB4 Mobile app allows for smartphone logging, tuning changes, and adjustment.
