Instant Power with Easy Plug & Play Installation
Ready to take your BMW N20 turbo to the next level? How about up to 50hp to the wheels (65hp crank) on a completely stock car or up to 100hp to the wheels (120hp crank) on a fully modified car? The JB4 features a simple plug and play installation harness for easy installation and includes many features not found on any other tune, including:
- Ability to enable/disable the tuning from the driver's seat
- Gear-dependent boost control to help with traction
- E85 compatibility
- Built-in diagnostic code reading/deleting
- Expanded engine safety systems
- Free firmware updates
- In-dash boost gauge
- Ability to control the exhaust flapper using your BC button
- And much more
The JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. For more advanced enthusiasts, the BMS DATA or JB4 Mobile cable allows you to connect a laptop or smartphone for additional gauges, data logging, and free firmware updates as we add new features and maps.
Additional Features:
- Full plug and play device that installs and removes in minutes at home without special tools.
- DME is never aware it's running more than the factory power levels.
- Not VIN locked and can be moved to your next vehicle or resold.
Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. A separate JB4 Mobile app purchase is also required.
Notes:
- The X1 & Z4 N20 JB4 is very different than the F series N20 JB4, using special firmware and a different CAN mounting location.
- Some F10 and X chassis models require a JB4 mobile adapter or BMS data cable to select options bit#1 to enable the in-dash controls for those models.
