JB4 Plug and Play Performance Tuner

The Burger Motorsports JB4 Tuner, now including the JB4PRO adapter and free app, is engineered for the 2023+ Mercedes-Benz AMG 2.0L Hybrid Turbo engine. This system offers a quick, plug-and-play installation, connecting to two key sensors to safely increase turbocharger output by 3-6psi. It enhances performance by rescaling timing and fueling for the boosted output, and the installation is fully reversible in seconds. The JB4 utilizes CANbus integration, providing a more advanced and responsive tuning experience compared to standard 2-channel systems. This allows for a smoother drive and improved overall performance. The tuner is housed in a durable billet aluminum enclosure and is designed and assembled in the USA, backed by a 5-year warranty. Enhance your driving experience with wireless connectivity via Bluetooth 4.0 to an iOS or Android device using the free JB4PRO app. This app enables data logging, performance map adjustments, and firmware updates. The JB4 tuner is compatible with various engine configurations including the 2.0L Turbo Mild Hybrid / Electric Turbo (M139l) found in the C43 Sedan, GLC 43 SUV/Coupe, SL 43 Roadster, and GT 43 Coupe. It also supports hybrid applications like the C63 SE Performance Sedan and GLC 63 S E Performance SUV/Coupe. For optimal performance, a minimum of 91 octane fuel is required.
