BMS JB4 Tuner for Kia / Hyundai / Genesis 2.5T StartStream including N (V2)

BMS JB4 Tune for Kia / Hyundai / Genesis 2.5T StartStream including N (V2)

Power gains of up to 65hp and 80tq to the wheels on a stock vehicle
The JB4 is a plug and play Kia / Hyundai / Genesis tuner that plugs into 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.
Unlike other tuning systems the JB4 includes a fully programmable CANbus system, upgradable firmware, and data logging capability. CANbus allows the JB4 to take into account pedal input, throttle position, gear, engine speed, air/fuel ratio, fuel trims, ignition advance, knock, and many other factors and incorporate those into the performance mapping. It can also read/delete fault codes, includes unique safety features such as keeping boost pressure low until oil and water is up to temperature to provide proper engine and turbo lucubration and drop to a low boost map if the engine starts to overheat, run lean, excessively knock, or over boost.
The JB4 offers a lot more performance, functionality, and safety than your average performance chip.

The default JB4 map1 runs 4psi over stock peak and tuned maps, including stock and valet mode can be selected on the fly using a BMS diagnostics cable or JB4 mobile smartphone adapter.

Installation is very discrete and it quickly removes without a trace when needed. Includes maps for 91 octane, 93 octane, and E85 (ethanol fuel) mixtures. Fuel economy during normal driving is unchanged. Compatible with all driving modes.

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.
JB4 Mobile by DMAC was released in 2014 and has become the gold standard for phone-to-tuner integration with its unique gauge display options/themes and advanced security systems. The JB4 Mobile app is purchased separately for $29 and requires the JB4 Mobile adapter.
JB4PRO by Burger Motorsports is our brand-new in-house adapter designed from the ground up for ease of use and reliability. Our new adapter fits fully inside the JB4 enclosure for enhanced weather protection and a more streamlined look.

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.
