The JB4 is a plug and play Kia / Hyundai tuner that plugs into two easy to access sensors in the engine bay and works with your factory ECU tuning to remap your boost, timing, spark 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. 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 plug in chip 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.
