The 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-app map switching between factory and various performance maps, boost limiting by gear for improved traction in lower gears, progressive water\/methanol support, built-in data logging, built-in code reading, 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 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 and is sold in over 67 countries worldwide.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eIs the JB4 a real tune?\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eYes the JB4 is a real tune. By tapping into specific sensors and CANbus for real time vehicle data the JB4 is able to alter your boost, timing, AFR, and\/or fuel trims, to a similar degree an ECU reflash would, but without the vehicle ever knowing its been tuned. The result is safe, smooth, and significant power and torque gains while retaining your factory safety systems and without having to unlock\/flag your ECU.\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003cspan\u003e\u003cu\u003e\u003c\/u\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/burgertuning.com\/pages\/faq\"\u003e\u003cspan\u003e\u003cu\u003e\u003cimg alt=\"JB4 FAQ\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/jb4-faq-bms-2400_ebe313c1-7832-4131-8f06-a40f5b967b9f_1024x1024.jpg?v=1578019911\"\u003e\u003c\/u\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGen 3 B48 Install Guide\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/jb4tuned.com\/instructions\/GEN3-B48-BMW-JB4-Install-Guide.pdf\"\u003e\u003cspan\u003e\u003cspan face=\"-apple-system, BlinkMacSystemFont, San Francisco, Segoe UI, Roboto, Helvetica Neue, sans-serif\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/Download-the-install-guide-2020-1.svg\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGen 3 B58 Install Guide\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003ca href=\"https:\/\/jb4tuned.com\/instructions\/B58TU2-JB4-Install-Guide.pdf\"\u003e\u003cspan face=\"-apple-system, BlinkMacSystemFont, San Francisco, Segoe UI, Roboto, Helvetica Neue, sans-serif\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/Download-the-install-guide-2020-1.svg\"\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"style-scope ytd-watch-metadata\"\u003e\u003cstrong\u003eGEN 3 B58 Shocking Dyno Reveal: Our 2025 BMW M340i Pushes \"30PSI\"\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/jxvAgGiFLmg?si=WJKQONozaRaWb-c3?rel=0\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eStock vs. JB4 Dyno Results\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003e2\u003c\/span\u003e\u003cspan\u003e023 G70 B\u003c\/span\u003e\u003cspan\u003eMW\u003c\/span\u003e\u003cspan\u003e 7 Series 740i B58\u003c\/span\u003e, no other mods\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/g70-bmw-7-series-b58-dyno_1024x1024.jpg?v=1684364105\" alt=\"2023+ G70 BMW 7 Series 740i B58 3.0L 6-cylinder dyno specs tuner tune\"\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/jb4_b58gen3_dyno_1024x1024.jpg?v=1684363975\" alt=\"2023+ G70 BMW 7 Series 740i B58 3.0L 6-cylinder dyno specs price tuner JB4\"\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"Burger Motorsports","offers":[{"title":"OBD Wired Connection (Steering Wheel Controls)","offer_id":43048019034230,"sku":"JB4-B48B58GEN3-OBD","price":1399.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1217\/5090\/files\/mode-auto-concepts-australia-bms-jb4-tuner-bosch-md1-mg1-06-2020-_-solution-audi-bmw-cupra-mercedes-benz-amg-skoda-vw-obd-cable-wired-data-connection-1.jpg?v=1684821511","url":"https:\/\/modeautoconcepts.com\/products\/bms-jb4-tuner-for-b48-b58-gen-3-bmw-2-3-4-5-7-x1-x3-x5-x6-x7-g-series","provider":"MODE Auto Concepts","version":"1.0","type":"link"}
