The JB4 tuner installs between your car's sensors and its DME\/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way the JB4 separates itself from the competition with much more advanced connection points and processing including CANbus, fuel \u0026amp; spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade.\u003c\/span\u003e\u003c\/p\u003e\n\u003ca href=\"https:\/\/www.n54tech.com\/instructions\/JB4_S58_INSTALL.pdf\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/Download-the-install-guide-2020-1_1024x1024.png?v=1590871760\" alt=\"\" data-mce-src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/Download-the-install-guide-2020-1_1024x1024.png?v=1590871760\"\u003e\u003c\/a\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003cp\u003e \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/s58-bmw-engine-tune-vs-b58-s55-jb4-tuner_1024x1024.jpg?v=1591655403\" alt=\"S58 BMW engine tune vs b58 vs s55 tuner JB4 XM3 XM4 M3\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDYNO\u003cbr\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/BMW_X4M-JB4-dyno_1024x1024.jpg?v=1580197539\" alt=\"X4M X3M BMW JB4 DYNO\"\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/S58-bmw-x3m-x4m-jb4-tuner-tune-flash_1024x1024.jpg?v=1610580112\" alt=\"JB4 tuner chip for S58 BMW X3m X4m X3m competition X4m competition\"\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/bmw-X4M-tuner-jb4-burger-motorsports-tuning-bms-aftermarket-parts_1024x1024.jpg?v=1567401083\" alt=\"BMW X4M X3m Tuner JB4 Burger Motorsports Tuning BMS Aftermarket Parts\"\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cb class=\"bigblack\"\u003e\u003cb class=\"bigblack\"\u003eDRAGY TIMES\u003cbr\u003e\u003cbr\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/jb4-tuned-x4m-stock-vs-jb4-tuned-0-60-mph_1024x1024.jpg?v=1567449009\" alt=\"X4M dragy times  0 - 60 MPH JB4 tuner Burger Motorsports\"\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/b\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cb class=\"bigblack\"\u003e\u003cb class=\"bigblack\"\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/bmw-x4m-quarter-mile-time-jb4-vs-stock_1024x1024.jpg?v=1567524784\" alt=\"BMW X4m S58 1\/4 mile time JB4 tuned vs Sock\"\u003e\u003c\/b\u003e\u003c\/b\u003e\u003c\/p\u003e","brand":"Burger Motorsports","offers":[{"title":"Default Title","offer_id":41467787378850,"sku":"JB4_S58 + Long OBDII cable","price":1116.92,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0527\/9953\/7314\/products\/bmw-m3-m4-jb4-tune-tuner-burger-tuning_8130af04-f19c-4b61-96f4-379839d9ccc3.jpg?v=1640621159","url":"https:\/\/broxtuning.ca\/products\/s58-jb4-for-2020-bmw-x3m-x3mc-x4m-x4mc-1263058","provider":"Brox Tuning","version":"1.0","type":"link"}
