{"product_id":"n63-n63r-n63tu-jb4-tuner","title":"N63\/N63R\/N63TU JB4 Tuner","description":"The Burger N63\/N63R\/N63TU JB4 Tuner is a sophisticated plug-and-play tuning system engineered to significantly enhance the performance of turbocharged BMW engines.\n\nThis device connects between your car's sensors and the DME\/ECU, allowing for real-time manipulation of boost, timing, and fuel trims to achieve gains comparable to an ECU reflash, but without altering the factory ECU. It boasts an impressive list of features including up to 100hp and 140tq gains at the wheels on stock vehicles, improved 0-60 and quarter-mile times, multiple tuning maps for various fuel types, and compatibility with E85 ethanol blends. The JB4 also reads and deletes fault codes, displays and logs up to 40 engine parameters, and includes boost-by-gear control for optimized traction. It integrates seamlessly with all driving modes and runs as smoothly as stock, with no impact on fuel economy during normal driving.\n\nThe tuner is housed in a billet aluminum enclosure and comes with a 5-year warranty. It is not VIN locked, ensuring it can be easily removed and transferred or resold. The JB4 also features full CANbus integration and is compatible with locked ECUs without requiring an ECU flash.\n\nConnectivity is further enhanced with the included JB4PRO adapter, enabling wireless connection to an iOS or Android device via Bluetooth 4.0. This allows for recording and analyzing vehicle data, changing performance maps, and updating firmware through the free JB4PRO app, which offers an intuitive interface and advanced log analysis tools.\n\nFitment requires careful attention to specific N63 engine variants (N63 TYPE_A, N63 TYPE_B, N63TU, and N63R) across various BMW 5, 6, 7, 8, and X Series models. Some applications may require checking sensor references. For models not explicitly listed, customers are advised to contact sales@burgertuning.com to verify JB4 fitment. The product requires 91 octane or better for performance gains.","brand":"Burger","offers":[{"title":"Default Title","offer_id":52687317434680,"sku":"N63\/N63R\/N63TU JB4 Tuner","price":779.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660683520.webp?v=1784882574","url":"https:\/\/store.motormia.co\/products\/n63-n63r-n63tu-jb4-tuner","provider":"MOTORMIA","version":"1.0","type":"link"}
