The BMS Pedal Tuner is a BMW Performance Chip with a pre-programmed internal chip that intercepts the stock signals from your BMW's electronic control unit (ECU) and changes them to achieve better performance by adjusting the air-fuel ratio and spark timing. Made specifically for the BMW inline six-cylinder motors. The PBX also has an adjustable throttle feature that can be combined with the Performance chip feature by selecting a setting or "map". The BMS Pedal Tuner contains both a performance chip which gives you an extra 8-10 Horsepower at the wheels and an adjustable throttle boost feature that makes the gas pedal send a boosted throttle signal in increments of 30%, 60%, and 100% over the stock BMW signal. Depending on what setting/ "map" you select you can create a perfect blend of throttle response. The BMS Pedal Tuner will make your vehicle more responsive, spirited and fun to drive. It will make your vehicle faster by increasing the horsepower and torque. It works well with other modifications like intakes and exhausts, but can also be used alone. It will remove the "dead space" when you push on the non-responsive stock BMW accelerator. It changes the way the car drives and feels. You can turn it on and off from the comfort of your driver's seat to feel the difference. The BMS Pedal Tuner is a clear choice. Features: Throttle Re-mapping for Better Response / Reaction Removes "dead area" delay in gas pedal 7 Different Maps / Settings for more enjoyable driving Can be set and turned on and off from inside the car Invisible to dealers equipment Made in USA

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.

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 on-board 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. Features: More Power: Max gains of up to +45 HP and +38 lb-ft TRQ (Crank); +39 HP and +34 lb-ft TRQ (Wheel). Bluetooth smart (Android and iOS Compatible). App download/pairing process is detailed within the installation instructions located under the Tech Resources dropdown below. 7 power levels and a bypass setting to choose from. Smooth and predictable power delivery. On-board diagnostics and factory safeguards maintained. Unaffected by dealer factory updates. Plug and play installation. 14-day satisfaction guarantee. 1 year limited warranty. NOTE: The DINANTRONICS X offers an array of different power levels (maps). These maps range from a bypass/stock setting at map 0 to a maximum power setting at map 7. The unit is shipped in map 5. This middle ground setting should be acceptable for all vehicle/engine configurations. However, you can adjust up or down as you see fit for your needs and/or modifications. Please note however that for each map level, we highly recommend the minimum fuel octane rating to run listed below. If you sense any unusual or unexpected behavior immediately turn down the map to a lower setting that did not exhibit the condition. MAP (S) / MINIMUM OCTANE 1-3 - 91 4-5 - 91/93 6 - 93 7 - 93+ *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.

Flash tuning meets convenience and versatility with a feature-rich handheld device. That's right - the most significant and important performance enhancement available for your turbo-charged car is now deliverable from the comfort of your drivers' seat. With multiple octane calibrations dependent on your specific needs, desires, or limitations nestled in the palm of your hand you can switch to the appropriate map with the click of a few buttons and a short flash. The main component of the DINANFLASH Handheld is the B58(M0) and 'F' Chassis B46 Dinan performance engine software loaded onto the device which is your ticket to maximum power. Not just any power, however - safe, reliable power that does not sacrifice the long-term health of the engine. Dinan performance engine software is so much more than just turning up the turbo boost after all. It is a fully re-tuned engine management program that maximizes power while keeping all the BMW factory safeguards in place. In most cases, Dinan software engineers also implement their own additional safety precautions in order to guarantee flawless performance that may not have been needed with factory power levels/programming. Protecting your BMW, while giving the most performance, is the definition of "Performance Without Sacrifice". To do just that, drivetrain and engine components are analyzed for strength, and then the calibration is tested on the dyno and in the real world for durability and drivability. This process has been a cornerstone of Dinan software development for decades and a major reason why Dinan performance tunes are often labeled as being the smoothest, factory-like solution in the marketplace. While the tune itself is the most noteworthy aspect of the DINANFLASH Handheld it is also much more than just an improved delivery mechanism for the masses. It is loaded with additional features that assist in monitoring, logging and troubleshooting as well. These features allow increased visibility on the inner workings of the engine/vehicle and help to ensure that the car is functioning at peak performance at all times. Important Notes: 1. DINANFLASH Handhelds are DIY and thus are at your own risk. Dinan is not responsible for consequential damages (neither parts nor labor) that may be caused as a result of the installation or use of this product. 2. The B58(M0) and 'F' Chassis B46 engines and their multitude of variants account for numerous unique box codes across various platforms. While Dinan has created files for many of these permutations, there is a chance you may have a box code that we have not seen. If this happens to be the case the handheld will prompt you to plug in the device to a computer after the unlock process in order to transmit relevant data to Dinan. We ask that you give us a call at 1-800-341-5480 when this has occurred so we can expedite the request. File creation typically occurs within 24-48 hours and will be available once the DINANFLASH Handheld is updated with new software via the Update Agent. Additional information about this process can be found in the user manual as well as the FAQ. 3. It is recommended that you update your DINANFLASH Handheld unit upon receipt via the Update Agent software to ensure the device is loaded with the most recent software/firmware. Features: ECU flashing at home courtesy of a palm perfect handheld device equipped with a high definition 2.8" color screen and an easily navigable graphic interface that plugs into the OBD2 port. One device supports and can flash Dinan software for either the B58(M0) or 'F' Chassis B46 engine. More Power: Max gains between 50-98 WHP / 67-120 lb-ft of torque depending on octane for the B58(M0) engine and max gains between 39-84 WHP / 54-121 lb-ft of torque depending on octane for the 'F' chassis B46 engine. Multiple octane calibrations (91, 93, 100 and 104) that can be flashed in moments directly from the handheld. 104 mapping only available for the B46 engine. Full map rescaling for drivability from idle to wide open throttle and everywhere in between. Optimized boost control, cam phasing, fueling, airflow and temperature controls for maximum power output that is also safe and reliable. Top speed governor (VMAX) removed. Sport gauges rescaled to reflect higher than stock power output. Retains all BMW factory engine safeguards and adds additional safety precautions such as the stationary rev limiter being set to 5000 RPM. Vehicle monitoring and logging capabilities. Up to 8 PID's monitored at a time with up to 4 displayed on screen. Read and clear diagnostic codes. One device can flash multiple VINs for maximum vehicle versatility (only one can be paired at a time). Upgradeable from DINANTRONICS Elite (V1 or V2) at a discounted rate via trade-in program. See the FAQ linked below for details. Free software updates for life via the Update Agent software. DINANFLASH Handhelds carry a 1 year limited warranty.

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 on-board 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 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.

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. Until then a JB4 mobile adapter or BMS data cable is required for any map and setting changes.
