Power gains of up to 70whp and 60wtq

This plug and play tuner attaches to two easy-to-access sensors in the engine bay and works with your factory ECU tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. It features a 64mhz processor allowing sensors to be sampled 800 times per second using dedicated 10-bit digital to analog converters, ensuring smooth and powerful performance.

Installation is very discrete and unlike flash remaps it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged. Compatible with all driving modes.

JB4 adds functionality with a plug and play OBDII CANbus connection allowing the JB4 to take in critical engine data directly from the ECU. Including pedal position, throttle position, timing advance, fuel trims, air/fuel ratio, engine knock, and much more. Other tuners without CANbus are not able to even monitor this critical engine data, no less incorporate it real-time into their tuning algorithms. The result is huge power increases with unparalleled power delivery.

The JB4 also features multiple maps based on this expanded engine criteria, smoother partial throttle performance, additional engine safety systems such as lean run or over boost, more advanced logging for those wanting to experiment with different fuels and E85 mixtures, boost by gear to improve traction, the ability to read and delete fault codes, and much more to come via free firmware updates. Made in the USA. 5 Year Warranty.

Wirelessly Connect to your JB4: Grab our all-new JB4 PRO smartphone connection to wirelessly connect the JB4 BMW tuner to your Bluetooth 4.0 compatible iOS or Android device. This option allows 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. Our new adapter fits fully inside the JB4 enclosure for enhanced weather protection and a more streamlined look. The JB4PRO Free app features an intuitive easy-to-use interface, help buttons, and advanced log analysis tools that can estimate the performance of your car and help identify any tuning concerns.

What is a JB4?

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, Bluetooth to your smartphone, 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.

Is the JB4 a real tune?

Yes the JB4 is a real tune. By tapping into specific sensors and CANbus for real time vehicle data the JB4 is able to alter your boost, timing, AFR, and/or fuel trims, to a similar degree an ECU reflash would, but without the vehicle ever knowing its been tuned. The result is safe, smooth, and significant power and torque gains while retaining your factory safety systems and without having to unlock/flag your ECU.

I used these shelves for my espresso area and I love them. The unboxing experience was so nice, it caught me off guard! Everything felt very handcrafted and sturdy. The finish on the real wood was very nice. It came with everything I needed for installation, which was very convenient. Installation was super easy and everything fit together perfectly. I am very pleased with these shelves!

Finally, great shelves!
Color: Walnut - Warm Brown Woodgrain, Number Of Shelves: Pack of 4, Size: 30 inch
Having tried several shelves, this is by far the best product we have received. These shelves are real wood, well cut and prepared, with very easy installation and are quite stable. They look wonderful in the bedroom we purchased them for, and we like them so much that we have just order another set for another room. These shelves are well worth every penny, and came with a beautiful thank you card from the small business from whom we purchased them...we thank them!

Beautiful floating shelves. Worth the price.
Color: Honey Oak - Warm Amber Tone, Number Of Shelves: Pack of 2, Size: 12 inch, Color: Honey Oak - Warm Amber Tone, Number Of Shelves: Pack of 2, Size: 12 inch
Love these shelves. Hanging them was incredibly simple. They came with a level to really help ensure they were straight. Directions were precise and easy to understand. Took me longer to decide where and how I wanted to place them than it did to hang them. Literally took me 5 minutes to actually hang both shelves. They are smooth, easy to dust and look amazing in all lighting. They are packaged well so I had no missing pieces and no damage. Super strong hold and I love that the bottom of each shelf has a screw to secure the bracket to the shelf so they don't fall. Where I live, that is a major plus because we have a train that comes through regularly and they haven't loosened a bit. Super pleased with this product.

Absolutely love these floating shelves. We bought three 30" and two 12". The quality exceeded my expectations. They feel incredibly solid, well-made, and high end. From the moment the package arrived, I could tell this company really cares about their product and their customers. Everything was packaged so elegantly and thoughtfully, with great attention to detail. Installation was straightforward, and once mounted, the shelves looked absolutely beautiful. What really stood out was the customer service. It was honestly some of the best I’ve experienced on Amazon. Super responsive, helpful, and genuinely caring. You can tell this is a company that takes pride in what they do. Highly recommend these shelves to anyone looking for something stylish, durable, and backed by amazing customer support

good
Size: 23.6 Inch, Color: White
I recently added this bathroom shelf, and it’s been a great upgrade for organizing my space. It was easy to install and feels sturdy enough to hold everyday essentials like toiletries, skincare products, and small containers without any issues. The design is simple and clean, which helps it blend in nicely with the rest of the bathroom. It doesn’t take up much space but still provides enough storage to reduce clutter around the sink or shower area. One thing I appreciate is how practical it is for small bathrooms—everything is within reach, and it makes the space feel more organized overall. As long as it’s installed properly, it holds up well and stays secure. The only downside is that heavier items might not be ideal depending on the material, but for regular use, it does the job perfectly. Overall, a functional and affordable solution if you’re looking to add extra storage and keep your bathroom tidy.
