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 and is sold in over 67 countries worldwide.\u003cbr\u003e\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: center;\"\u003eIs the JB4 a real tune?\u003c\/h3\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan\u003eYes the JB4 is a real tune.

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\u003c\/p\u003e\n\u003cp class=\"p1\" style=\"text-align: center;\"\u003e\u003cspan class=\"s1\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan\u003e\u003ca href=\"https:\/\/burgertuning.com\/pages\/faq\"\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\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003ca href=\"https:\/\/www.jb4tuned.com\/instructions\/s55_jb4_install.pdf\"\u003e\u003cimg alt=\"BMW F80 M3 F82 F83 M4 F87 M2 Competition install guide\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/Download-the-install-guide-2020-1.svg\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/burger-motorsports-bmw-m3_1024x1024.jpg?v=1574641207\" alt=\"Tags: bmw m3 f80 tuning, best tune, s55, 2015 2016 2017 2018 2019 m3 m4 tune, jb4 tuning software, bmw m3 tuner for sale, bmw m4 tuner m4 competition chip, bmw m4 upgrades stage 2, F82 bmw m4 tuning potential, bmw m4 jb4 dyno, performance chip\" style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/jb4-tuned-bmw-M4_1024x1024.jpg?v=1566953936\" alt=\"jb4 tuned bmw M4 bms burger tuning burger motorsports Tags: bmw m3 f80 tuning, best tune, s55, 2015 2016 2017 2018 2019 m3 m4 tune, jb4 tuning software, bmw m3 tuner for sale, bmw m4 tuner m4 competition chip, bmw m4 upgrades stage 2, F82 bmw m4 tuning potential, bmw m4 jb4 dyno, performance chip\" style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan\u003e \u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan class=\"bigblack\"\u003e\u003cb\u003eS55 BMW M3\/M4 JB4 Map Guide\u003c\/b\u003e\u003c\/span\u003e\u003cbr\u003e\u003cb\u003eMap 0:\u003c\/b\u003e\u003cspan\u003e Disable JB4 \/ Full Pass Through Mode \u003c\/span\u003e\u003cbr\u003e\u003cb\u003eMap 1:\u003c\/b\u003e\u003cspan\u003e Stage1 map adding approximately 40whp and 40wtq across the power band on pump gas.
