CARB APPROVAL: Approved Under Executive Order (EO) No. D-744-4 for all 2016-2018 BMW 230i, 330i, 430i, 530i, and X1 applications. The JB4 is the most advanced and highly featured tuning system available for your B38, B46, and B48 powered BMW. Power gains are up to 40hp to the wheels (55hp crank) for a B48, gains with bolt-on parts, higher octane, E85 mixtures, and larger turbos are even higher. 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. 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 those who are interested in logging, adding new features as we post them, etc, we suggest the BMS DATA cable or JB4 mobile phone adapter. The JB4 automatically detects between the B38, B46, B48 models at boot up making installation and setup a snap. 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. JB4 Map Guide: Map0: Stock tuning, fully disable JB4 Map1: 3psi over stock added (91 octane) Map2: 4psi over stock added (91-93 octane) Map3: 6psi over stock added (93+ octane) Map4: Absolute target map with peak target of 20psi (93+ and/or 30% E85, EWG connector suggested) Map5: Absolute target map with peak target of 22psi (30% E85+ fuel, EWG connector suggested) Map6: Custom tuning map -- see details on JB4tech.com B58 JB4 page Map7: Progressive WMI map with tuning a function of meth flow and user-defined boost additive. Map8: VALET / Low Boost Map JB4 Power Gains, Features, & Benefits Power gains of up to 100hp to the wheels on a stock vehicle Improves 0-60 times and 1/4 mile times Preloaded with custom JB4 BMW tuning software and up to 8 maps for various fuel and modification levels Ethanol (E85) compatible tuning maps Able to read/delete fault codes View and record up to 40 different gauges/engine parameters in real time with the JB4 app. Boost by gear in 1st, 2nd, and 3rd can be controlled via the JB4 app for a perfect launch Exhaust flap operation can be controlled in most JB4 applications Compatible with JB4 Mobile for smartphone logging, tuning changes, and adjustment The JB4 offers a lot more performance, functionality, and safety than your average performance chip Quick Plug & Play Installation CANbus OBDII integration offering unrivaled tuning features and performance Improved performance over non-integrated chip tunes Runs as smoothly as stock, this is how your vehicle should have come from the factory Compatible with all driving modes Fuel economy unchanged during normal driving 91 octane fuel or better required for performance gains Not VIN locked and can be removed without a trace and resold down the road Includes the rugged JB4 billet aluminum enclosure for protection Designed and assembled in the USA Free USA Shipping 5-year warranty Note for 2018+ G chassis vehicles with the digital dash layout we have not yet added in the JB4 commands to allow in-dash control but will provide those via a free firmware update once developed.
