JB4 Tuner

The Burger Motorsports JB4 Tuner is a plug-and-play performance module engineered for the 2022 and newer Lotus Emira, available for both the 2.0L I4 Turbo (M139) and 3.5L V6 Supercharged (2GR-FE) engines. This system works by connecting to sensors within the engine bay and interfacing with your factory ECU to optimize boost, timing, and fueling for enhanced performance and reduced turbo lag. It achieves power gains of 60-100 horsepower at the wheels without requiring an ECU flash, making it compatible with locked ECUs. This JB4 tuner includes the JB4PRO Bluetooth adapter and a free app, allowing users to wirelessly connect to their tuner. Through the app, you can analyze vehicle and tuning data, switch between performance maps, and update the JB4 firmware. The app also offers advanced log analysis tools to help assess performance and identify tuning concerns. Key features and benefits include power gains up to 100whp (depending on fuel), improved 0-60 and quarter-mile times, multiple tuning maps for various fuel types, quick plug-and-play installation, E85 support, fault code reading/deleting, display and logging of up to 40 engine parameters, boost-by-gear control, and exhaust flap operation control on compatible vehicles. It offers safer and more effective performance than basic chip tunes, with full CANbus integration and smooth stock-like operation across all driving modes. The tuner requires 91 octane or better for optimal performance gains and is not VIN-locked, allowing for easy removal and resale. Vehicle fitment is specifically for the 2022+ Lotus Emira, with dedicated support for the 2.0L I4 Turbo (M139) and the 3.5L V6 Supercharged (2GR-FE) engines. The tuner is designed and assembled in the USA and comes with a 5-year warranty.
