Power gains of up to 100hp and 100tq to the wheels on a stock vehicle The JB4 is a plug and play Kia / Hyundai 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. It features a 64mhz processor allowing sensors to be sampled 1000 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance. It's able to auto-detect between 3.3L, 2.0L, and 1.6L turbo engines automatically allowing for simple plug and play installation across the entire Kia / Hyundai turbocharged lineup! 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. Made in USA. 5 year warranty.It's well documented the Kia and Hyundai platforms are prone to spark blow out at both stock and higher than stock boost levels. At a minimum, the factory spark plug gap should be closed to 0.026". Alternatively, replacement spark plugs can be used that offer a stronger spark and are more reliable than stock.

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. 3.3L turbo install guide 1.6L turbo install guide (.PDF) 2.0L turbo install guide (.PDF) DYNO RESULTS 2018 Kia Stinger, JB4, 91 octane, BMS intake, BMS WMI Stinger stock vs. JB4, 91 octane, factory intake Stinger with JB4 map2, 91 octane, BMS intake Stinger with JB4, 30% E85, BMS intake 2021 Veloster N DCT, JB4 and intake, 91 octane + E25 VIDEO JB4 install on the Hyundai Veloster
