Power gains of up to 60whp and 100wtq on a factory vehicle without the risks of flashing!

The JB4 is a plug and play tuner that 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.

Installation is very discrete and unlike flash remaps, which are quick to install but can never be fully removed with a JB4 the vehicle is never aware it's making more than the factory boost or power levels. Fuel economy during normal driving is unchanged and it's compatible with all driving modes, including towing.

Unlike other less advanced systems, the JB4 includes CANbus functionality allowing it to take in critical engine data directly from the ECU for real-time tuning. The data includes pedal position, throttle position, timing advance, fuel trims, air/fuel ratio, engine knock, fuel trims, gear, and 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. CANbus allows the JB4 to provide huge power increases with unparalleled power delivery.

The JB4 includes multiple maps for 91 octane, 93 octane, factory tuning, VALET mode, E85 mixtures, and unleaded race gas. In addition, it offers boost by gear settings to improve launches, the ability to read and delete fault codes, and much more. The JB4 is made in the USA and includes a 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 and is sold in over 67 countries worldwide.

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.

Best most adorable dog toy
So Ivy and Archie got married they are therapy dogs at an assisted living and Jackson was the best man. We fashioned the box with a ribbon around Jackson’s neck but he was too interested in playing with the box for it too last. While the pastor was officiating the wedding the groom did eat the top of the ring off but we snagged it for the bride to wear on her wrist! This dog toy was the best prop ever so adorable well made and authentic! I highly recommend this toy as a prop for a dog wedding !!

If Your Dog Wants to Tie the Knot
This is about the only diamond ring toy of its type, for a dog, that I have been able to find, and it filled the need perfectly. I would have given it 5 stars, but I thought that the price was a few dollars higher than necessary. I needed it quickly though, and it was delivered in rural Tennessee within 48 hours. It's a 2 part dog toy that probably wouldn't hold up especially well if your dog is rough on stuffy toys. My girl is gentle, and it doesn't have any squeakers in it, so it will last. I imagine it will wash well in a garment bag, although I haven't done that yet. If your dog wants to tie the knot, this is the ring for you.
