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\u003cp\u003e\u003cstrong\u003eIs the JB4 a real tune?\u003c\/strong\u003e\u003c\/p\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\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\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\/p\u003e\n\u003ch3 class=\"bodytype\"\u003e\u003ca href=\"https:\/\/jb4tuned.com\/instructions\/Lexus_Stage1.pdf\"\u003e\u003cspan\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/Download-the-install-guide-2020-1.svg\" alt=\"\"\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/h3\u003e\n\u003ch3\u003e\u003cspan\u003eDYNO RESULTS\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003e2016 Lexus IS 200t stock vs. BMS JB4 tune, default settings\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/2048\/files\/image_101ca641-3640-42fd-8410-1e8c338b0376.png?v=1547856293\" alt=\"2016 Lexus IS 200t stock vs. BMS JB4 tune, default settings\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eJB4 Install Video\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/Z1blj-q0JKA\"\u003e\u003c\/iframe\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"797 Offroad","offers":[{"title":"Default Title","offer_id":51352514363616,"sku":"Lexus JB4 Tuner + PRO BT Adapter","price":599.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0610\/0654\/5120\/files\/lexus-jb4-performance-tuner_48c0c014-8a52-4cf8-bdb6-b50b54014d83.jpg?v=1775495256","url":"https:\/\/797offroad.com\/products\/lexus-jb4-tuner","provider":"797 Offroad","version":"1.0","type":"link"}
