Power gains are up to 120hp to the wheels (140hp crank) on a completely stock B58 engine on pump gas, gains with bolt-on parts, higher octane, E85 mixtures, and larger turbos are even higher.\u003cbr\u003e\u003cbr\u003eThe JB4 features a simple plug \u0026amp; play installation harness for easy installation \u0026amp; removal and includes many features not found with any other tune. Including on the fly in-dash map switching between factory and various performance maps, optional in-dash gauge displays for boost, boost limiting by gear for improved traction in lower gears, progressive water\/methanol support, built-in data logging, built-in code reading, optional direct EWG control to prevent throttle closure with exhaust modifications, exhaust flapper control, and much more. Other more expensive tuners may claim to equal the JB4's technology but upon closer examination lack most if not all of the JB4's features.\u003cbr\u003e\u003cbr\u003eRemember the JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customization, but for those who are interested in logging, adding new features as we post them, etc, we suggest the BMS DATA cable or REV3 mobile phone adapter. \u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eJB4 Map Guide:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eMap0:\u003c\/strong\u003e Stock tuning, fully disable JB4\u003cbr\u003e\u003cstrong\u003eMap1:\u003c\/strong\u003e 3psi over stock added (91 octane)\u003cbr\u003e\u003cstrong\u003eMap2:\u003c\/strong\u003e 4psi over stock added (91-93 octane)\u003cbr\u003e\u003cstrong\u003eMap3:\u003c\/strong\u003e 6psi over stock added (93+ octane)\u003cbr\u003e\u003cstrong\u003eMap4:\u003c\/strong\u003e Absolute target map with peak target of 20psi (93+ and\/or 30% E85, EWG connector suggested)\u003cbr\u003e\u003cstrong\u003eMap5:\u003c\/strong\u003e Absolute target map with peak target of 22psi (30% E85+ fuel, EWG connector suggested)\u003cbr\u003e\u003cstrong\u003eMap6:\u003c\/strong\u003e Custom tuning map -- see details on JB4tech.com B58 JB4 page\u003cbr\u003e\u003cstrong\u003eMap7:\u003c\/strong\u003e Progressive WMI map with tuning a function of meth flow and user-defined boost additive. \u003cbr\u003e\u003cstrong\u003eMap8:\u003c\/strong\u003e VALET \/ Low Boost Map\u003cbr\u003e\u003cbr\u003eNote for 2018+ G chassis vehicles with the digital dash layout we have not yet added in the JB4 commands to allow in-dash control but will provide those via a free firmware update once developed.

The JB4 tuner installs between your car's sensors and the 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\u003cp\u003e\u003cspan\u003e\u003cu\u003e\u003ca href=\"https:\/\/burgertuning.com\/pages\/faq\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/jb4-faq-bms-2400_ebe313c1-7832-4131-8f06-a40f5b967b9f_1024x1024.jpg?v=1578019911\" alt=\"JB4 FAQ\"\u003e\u003c\/a\u003e\u003c\/u\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.n54tech.com\/instructions\/JB4_BMW_B48_B58_Install_Guide.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=\"\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.n54tech.com\/instructions\/JB4_BMW_B48_B58_INSTALL_CARB.pdf\"\u003eCalifornia Customers -- Download the CARB Version Installation Guide\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Burger Motorsports","offers":[{"title":"Gen 1 B58","offer_id":45223528824994,"sku":"BMS-B58-JB4","price":838.6,"currency_code":"CAD","in_stock":true},{"title":"Gen 2 B58","offer_id":45589195358370,"sku":"BMS-B58-JB4","price":838.6,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0527\/9953\/7314\/files\/jb4-tuner-00002.webp?v=1777322634","url":"https:\/\/broxtuning.ca\/products\/jb4-for-bmw-gen1-gen2-b58-1xxit","provider":"Brox Tuning","version":"1.0","type":"link"}
