{"product_id":"jb4-performance-tuner-for-n54","title":"JB4 Performance Tuner for N54","description":"The Burger Motorsports N54 JB4 is a plug-and-play performance tuner engineered to significantly enhance the power output of BMW's twin-turbocharged N54 engines. It provides an instant horsepower boost, with claims of up to 100 crank horsepower and 80 wheel horsepower on a stock vehicle, and can support up to 350 wheel horsepower on heavily modified cars with larger turbochargers.\n\nInstallation is designed to be straightforward using a simple plug-and-play harness, and the JB4 is compatible with all N54 ECU versions and transmission types, including DCT. The tuner offers a variety of features for customization and control. These include multiple performance maps that can be changed \"on the fly\" from the driver's seat, a 100% stock bypass map for returning to factory settings, and a valet mode.\n\nFurther enhancing its versatility, the N54 JB4 supports advanced fueling options such as ethanol fuel (E85) and progressive water\/methanol injection. It also includes features like an automatic tuning map that adapts to environmental and vehicle conditions, a racing fuel map, and an RPM-adjustable map for fine-tuning. Optional enhancements available include in-dash gauges for boost and other parameters, a programmable shift light, on-the-fly adjustable torque limiting for improved launches, and for manual transmission cars, an optional 2-step rev limiter and no-lift shifting.\n\nThe JB4 is designed to be the first and only modification needed to unlock a new level of performance, and it scales with further modifications. Its applications cover a range of BMW models including the 1 Series (E82\/E88 135i, E82 1M), 3 Series (E90\/E91\/E92\/E93 335i\/xi, E92 335is), 5 Series (E60\/E61 535i\/xi), X6 (E71 xDrive35i), and Z4 (E89 sDrive35i).","brand":"Burger Motorsports","offers":[{"title":"Default Title","offer_id":52687319826744,"sku":"N54 JB4","price":479.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687892345.webp?v=1784882615","url":"https:\/\/store.motormia.co\/products\/jb4-performance-tuner-for-n54","provider":"MOTORMIA","version":"1.0","type":"link"}
