Kia / Hyundai 1.6L Turbo 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. Wirelessly Connect to your JB4: Includes our all-new JB4PRO smartphone connection to wirelessly connect the JB4 via Bluetooth to your iOS or Android device.

The JB4PRO Free app allows you to change maps, record and analyze vehicle and tuning data, and update JB4 firmware as we release newer versions with updates, more powerful maps, and new features under development. Our new adapter fits fully inside the JB4 enclosure for enhanced weather protection and a streamlined look.

The JB4PRO Free app features an intuitive easy-to-use interface, help buttons, and advanced log analysis tools that can estimate the performance of your car and help identify any tuning concerns. Kia / Hyundai
