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.

This boost controller was designed from the beginning to be easily installed and even easier to use. It plugs into a sensor and uses the factory DME to re-map boost, timing, and fuel maps.

The app contains a live boost monitor that streams data in real time.

The DINANTRONICS X is the newest installment of the highly successful Dinan foray into inline tuning modules. Like its predecessors, it is a highly engineered piece of computer hardware and software that enhances engine performance to levels the stock programming is not allowed to venture. It does this without affecting long-term reliability or the functionality of onboard diagnostic systems when run under recommended operating variables. Unlike its predecessor, however, the DINANTRONICS X is Bluetooth smart and offers convenient access to the adjustment of power levels directly from the palm of your hand. A further advancement beyond its entry-level little brother, the DINANTRONICS SPORT, X connects to additional inputs and/or has a more refined tuning strategy that yields more power as a result. For those that do not wish to (or can't) alter their stock ECU with a more robust engine flash the DINANTRONICS X is a perfect alternative to satiate the craving for "more". Whichever level of engine tuning is ultimately chosen you can be sure to be pleased by the result. The Dinan Difference is possible by employing a full staff of talented engineers that are well rounded in many facets of automotive engineering and backed by a wealth of hands-on knowledge. Stemming from diverse backgrounds not only on racing teams but on standard factory production line vehicles, we have seen it all. Manipulating these signals/maps with an adept hand, all the while keeping an engine running at its best and with the most reliable power, is what Dinan is all about. NOTE: D440-0153 does not apply to the 2020 M340i. Please use D440-0152 (ES4499647) for that specific application. Features: More Power: Max gains of up to +60 HP and +91 lb-ft TRQ (Crank); +55 HP and +80 lb-ft TRQ (Wheel). Bluetooth smart (Android and iOS Compatible). 7 power levels and a bypass setting to choose from. Smooth and predictable power delivery. On-board diagnostics and factory safeguards are maintained. Unaffected by dealer factory updates. Plug and play installation. 14-day satisfaction guarantee. 1-year limited warranty - DINANTRONICS X does not carry the factory matching warranty that Dinan is known for. DINANTRONICS X's warranty is a 1-year, product-only warranty, that does not cover consequential damages or labor reimbursement.
