{"product_id":"jb4-b58-tuner","title":"JB4 B58 Tuner","description":"The Burger JB4 B58 tuner from Burger Motorsports is the most advanced plug-and-play tuning system available for BMW B58 turbocharged engines. It is designed to deliver significant power gains of up to 120 horsepower and 120 lb-ft of torque at the wheels on a completely stock B58 engine running on pump gas. For those with bolt-on upgrades, higher octane fuel, E85 mixtures, or larger turbochargers, even greater gains are possible.\n\nThis tuning system features a simple plug-and-play wiring harness for quick installation and removal, while providing advanced tuning capabilities. It includes on-the-fly map switching, boost-by-gear control, progressive water\/methanol integration, fault code reading and clearing, and direct electronic wastegate control. Unlike traditional ECU flash tuning, the JB4 does not require staged upgrades or permanent ECU modification, allowing for immediate experience of stronger turbo response, smoother power delivery, and significantly improved acceleration.\n\nThe JB4 includes the JB4PRO adapter and free app, allowing wireless connection to a Bluetooth 4.0 compatible iOS or Android device. This enables users to record and analyze vehicle data, change performance maps, and update firmware. The JB4 is compatible with GEN1 and GEN2 B58 engines and is CARB approved under Executive Order D-744-4 for many 2016-2018 BMW applications. It offers superior performance and safety compared to basic chip tunes and includes a billet aluminum enclosure, with a 5-year warranty.","brand":"Burger","offers":[{"title":"Default Title","offer_id":52687306391864,"sku":"JB4-B58","price":529.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661174477.webp?v=1784882431","url":"https:\/\/store.motormia.co\/products\/jb4-b58-tuner","provider":"MOTORMIA","version":"1.0","type":"link"}
