Description

The BurgerMotorsports JB4 tuner, specifically the Kia V2 Harness + PRO BT Adapter, is a sophisticated engine management system for turbocharged Kia, Hyundai, and Genesis 2.5T SmartStream engines. This plug-and-play device interfaces with your vehicle's existing sensors and ECU to optimize performance by recalibrating boost pressure, ignition timing, and fuel delivery, resulting in reduced turbo lag and enhanced power. Unlike simpler tuning solutions, the JB4 boasts advanced CANbus integration, enabling it to process a wide array of real-time data—including throttle position, engine speed, air/fuel ratios, knock detection, and more—to dynamically adjust its performance maps. This tuning system is built with safety and functionality as priorities. It incorporates features such as delaying boost engagement until the engine and turbocharger reach optimal operating temperatures for proper lubrication, and automatically reducing boost if the engine experiences overheating, lean conditions, excessive knock, or over-boosting. The JB4 offers multiple tuning maps tailored for various fuel types, including 91 octane, 93 octane, and E85 ethanol blends, and allows for on-the-fly map selection. A key feature of this version is the included JB4 PRO Bluetooth adapter, which enables seamless wireless connectivity to an iOS or Android device via Bluetooth 4.0. This allows users to monitor and analyze critical vehicle and tuning data, switch between JB4 performance maps, and receive free firmware updates, including new maps and features as they become available. The dedicated JB4PRO app provides an intuitive interface with helpful guides and advanced log analysis tools for performance estimation and troubleshooting. Key benefits and features include power gains of up to 65hp and 80tq to the wheels on a stock vehicle, improved 0-60 and quarter-mile times, boost-by-gear control for enhanced traction, the ability to read and delete fault codes, and support for exhaust flap control on compatible vehicles. The unit comes in a rugged billet aluminum enclosure, is designed and assembled in the USA, and is backed by a 5-year warranty. It is compatible with all driving modes, and fuel economy remains unchanged during normal driving conditions. The JB4 is not VIN-locked, allowing for easy removal and resale. Requires 91 octane or better fuel for performance gains.
