Kia & Hyundai 1.6T Gamma JB4 Performance Tuner (V1)

Power gains of up to 60whp and 60wtq to the wheels on a stock vehicle

Now includes the JB4PRO adapter and free app! 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.

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.

Installation is very discreet 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.

Also now available with our newJB4PRO board for more heavily modified cars which includes built in Bluetooth, built in ethanol sensor processing eliminating the need for a separate ECA, built in CPI/WMI control eliminating the need for a separate FSB, onboard data-logging memory, plug and play o2 bias wires, built in wiring ports for our 10 bar pressure sensors for low fuel pressure and/or coolant pressure, and includes many additional features to be unlocked in the future via free firmware updates! JB4PRO is the ultimate tuning tool for those looking to push their cars to the max!
