The JB4 Tuner for the N55 E Chassis BMW is a powerful performance upgrade that delivers significant gains in horsepower and torque. On a completely stock vehicle, it can provide up to 60 horsepower and 60 lb-ft of torque at the wheels (roughly 80 hp at the crank). When paired with other modifications like an upgraded intake, exhaust, and high-flow downpipe, it can boost power by up to 100 hp to the wheels (120 hp at the crank).
- Optional: For Extra Ordinary Performance with JB4 We also recommend Our N55 Downpipe
Performance Features
- Multiple Performance Maps: The JB4 offers up to 8 preloaded tuning maps to suit different fuel types and modification levels, with support for ethanol blends (E85).
- On-the-Fly Map Switching: Users can switch between factory and performance maps through in-dash controls without stopping.
- Boost Control: Fine-tuned control over boost in different gears for optimal launches and performance.
- Data Monitoring and Code Reading: Integrated OBDII CANbus data lets you read and delete fault codes, and the tuner offers real-time monitoring and logging of up to 40 engine parameters.
- Exhaust Control: Adjust the exhaust flap operation (applicable to most vehicles) for customizable sound and performance.
Ease of Use
- Plug & Play Installation: The JB4 installation is straightforward and requires no additional modifications. Simply plug it in and start enjoying enhanced performance.
- Bluetooth & Mobile Compatibility: Connect wirelessly via a Bluetooth 4.0 compatible device with the JB4 Mobile connect kit, or use the BMS data cable for a Windows laptop connection. This allows for map switching, data logging, firmware updates, and more.
- No VIN Locking: Unlike many other tunes, the JB4 can be easily removed without leaving a trace on the vehicle and resold if desired.
- Fuel Economy Maintenance: During normal driving, fuel economy remains unchanged.

How to tell if you need harness A or B
What is a JB4?
The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and the 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, Bluetooth to your smartphone, 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.
