Ready to take your F Chassis BMW N55 turbo to the next level?
How about up to 60hp to the wheels (80hp 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 the ability to enable/disable the tuning from the drivers seat, gear dependent boost control to help with traction, ethanol and racing fuel support, built in diagnostic code reading/deleting, free firmware updates, and much more.

Remember 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. The JB4 also does not require any user setup or customization but for more advanced enthusiasts the BMS DATA cable allows you to connect via a laptop for data logging and free software updates.

Note JB4_F30 shipments as of 11/15/2014 include the FlexFuel add on connector. This no longer needs to be purchased separately for these models. Also note the EWG add on connector remains optional and can be purchased separately for higher HP applications where direct EWG control is required.
