Unlike other tuning systems the JB4 includes a fully programmable CANbus system, upgradable firmware, and data logging capability. It's able to auto-detect between 1.6L and 2.5L turbo engines automatically allowing for simple plug and play installation across the entire Kia / Hyundai turbocharged lineup! 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.

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. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade.UPDATE - We have now tested on our Demo Car with the following results: In addition the JB4 system is not VIN locked to your vehicle and can be quickly removed without a trace and swapped between cars or resold at a later time. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows.

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. 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. The JB4 is a plug and play tune available for turbocharged vehicles.
