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.

JB4 takes your F95/F96 BMW X5M/X6M from factory stock to full race-ready performance, offering unmatched tuning capabilities. Designed for easy installation and complete removability, the JB4 requires no splicing or cutting of factory wires, making it the ideal choice for your S68 engine. The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its 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, 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.

RaceChip is the largest chip tuning company in the world! Their products are made in Germany and rigorously tested on the Autobahn. RaceChip offers the next generation of performance tuning. It allows for up to 30% more Horsepower and 20% better Gas Mileage with a very simple installation process. Unlock the untapped performance of your BMW engine with peace of mind from RaceChip. S: 5 Tune Mappings +32 HP +60 lb-ft Torque Up to +15% MPG Includes everything you need for installation, down to the cable ties. RS: 6 Tune Mappings +40 HP +75 lb-ft Torque Up to +20% MPG Includes everything you need for installation, down to the cable ties. GTS: 7 Tune Mappings +48 HP +90 lb-ft Torque Up to +20% MPG Limited 2 year engine warranty Built in warm-up timer One time reprogramming if used on different vehicle Includes everything you need for installation, down to the cable ties. XLR Throttle Controller: RaceChip developed the new XLR to increase responsiveness on the road. Their innovative throttle tuning system lets you tune your engine’s reactions to your taste – choose from 7 separate stages (Eco+, Eco, Neutral, Sport, Sport+, Race, and Race+). Your engine’s performance isn’t affected by RaceChip XLR, but you can access it more immediately and directly. Experience significantly sharper responses for yourself – no waiting for the message to get through or frustrating “pauses for thought”. And the best thing: installation is simple and requires no specialist knowledge. Try it now! The Brainbox: The Brainbox is the nerve center of XLR and controls the processes needed to optimize throttle response. The Brainbox’s compact size (ca. 70 x 80 mm) allows it to be fitted easily in the footwell of your vehicle. As it is so flat, it does not restrict the driver’s legroom at all. It can be fixed almost anywhere in the footwell, for example in existing slots or vents. The Controller: The XLR Controller allows you to choose between 7 stages: Eco+, Eco, Neutral, Sport, Sport+, Race and Race+. Each stage sharpens your car’s throttle response a little more, until in Race+ it’s like a thoroughbred sports car. You can mount the Controller anywhere in the car so that it’s in the right place for how you want to use it. The size and design mean it fits right in with the rest of the interior and the other control elements.

JB4 takes your G09 BMW XM / XM Label from factory stock to full race-ready performance, offering unmatched tuning capabilities. Designed for easy installation and complete removability, the JB4 requires no splicing or cutting of factory wires, making it the ideal choice for your S68 engine. The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its 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, 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.

Improve the range of your electric vehicle with Race Chip's innovative RaceChip RX. Adjust the RX with 3 individual stages exactly to your personal wishes and driving style. From the highest possible range to dynamic driving behavior with improved energy recovery. Range Extension Improved Energy Recovery Easy Installation 3 Individual Stages App Control The RaceChip RX is attached between the accelerator pedal sensor and the engine control unit. Simple plug & play installation means that it can be fitted without any prior technical knowledge. The signals emitted by the accelerator pedal sensor are adjusted via specially tuned characteristic curves. This results in a more linear torque demand on the electric motor and increased energy recovery when the accelerator pedal is released. As a result, less energy is lost and energy recovery is improved during braking; the same battery capacity will cover a longer distance.
