{"product_id":"jb4-tuner-n54","title":"JB4 Tuner N54","description":"The Burger Motorsports JB4 Tuner is a sophisticated performance module engineered to unlock the full potential of BMW's N54 engine. This unit installs via a simple plug-and-play harness, connecting directly between the vehicle's sensors and its DME\/ECU to actively manage and enhance performance parameters. It is compatible with all ECU versions and transmission types, ensuring broad application across the N54 engine platform.\n\nThis tuner offers substantial power increases, with stated gains of up to 80hp to the wheels (100hp crank) on a completely stock car. For vehicles with factory turbos, gains can reach up to 160hp to the wheels, and on fully modified cars with larger turbochargers, the JB4 can deliver up to 350hp to the wheels. Beyond raw power, the JB4 provides a range of advanced features including multiple on-the-fly selectable performance maps, a stock bypass map, valet mode, support for ethanol fuel (E85), progressive water\/methanol injection, and an auto-tuning map that continuously adjusts to current climate, octane, vehicle condition, and modifications.\n\nInstallation is designed to be straightforward, and the JB4 can be used as a standalone modification or scaled with further upgrades as the vehicle is modified. It is compatible with JB4 Mobile for smartphone logging and tuning adjustments via Bluetooth, or with a Windows laptop using a BMS data cable for data analysis and firmware updates. For optimal performance gains, 91 octane fuel or higher is required. The unit is not VIN-locked, allowing for removal without a trace and resale. It is made in the USA and backed by a 5-year warranty. Please note, this item is not CARB exempt and is not legal for sale or use in California.","brand":"Burger Motorsports","offers":[{"title":"Default Title","offer_id":52687324250424,"sku":"N54-JB4","price":379.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660191076.webp?v=1784882692","url":"https:\/\/store.motormia.co\/products\/jb4-tuner-n54","provider":"MOTORMIA","version":"1.0","type":"link"}
