It piggybacks the engine's sensor network over CANbus, so the car makes real power while the DME stays stock — no flash, no VIN lock, and no conflict with an over-the-air update. Burger Motorsports quotes power gains of up to 120hp and 120tq to the wheels on a stock B58 running pump gas, with more available on a modified car. Installation takes about 20 minutes with hand tools and it comes back off just as easily.\u003c\/p\u003e\n\u003cp\u003ePick the generation that matches your engine. Gen1 covers the earlier 2016–2019 B58 and is also offered in a CARB-approved version, which is the one you want if the car has to pass a California visual inspection. Gen2 covers the 2020+ B58 with the revised fuel system.\u003c\/p\u003e\n\u003cp\u003eBoth the standard JB4 and the JB4PRO include the JB4PRO Bluetooth adapter and the free app, so wireless map switching, live gauges, datalogging and firmware updates from your phone are standard either way. The JB4PRO is a different board built for heavily modified cars, and it is available on Gen2 cars only. Running stock or bolt-ons, the standard JB4 is the right call; building toward E85, port injection or methanol, go PRO.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePower gains of up to 120hp and 120tq to the wheels on a stock B58 running pump gas\u003c\/li\u003e\n\u003cli\u003eMap 0: stock tuning — JB4 disabled\u003c\/li\u003e\n\u003cli\u003eMap 1: +3 psi over stock (91 octane)\u003c\/li\u003e\n\u003cli\u003eMap 2: +4 psi over stock (91–93 octane)\u003c\/li\u003e\n\u003cli\u003eMap 3: +6 psi over stock (93+ octane)\u003c\/li\u003e\n\u003cli\u003eMap 4: absolute target map with a peak target of 20 psi (93+ octane and\/or E30)\u003c\/li\u003e\n\u003cli\u003eMap 5: absolute target map with a peak target of 22 psi (E30+ recommended)\u003c\/li\u003e\n\u003cli\u003eMap 6: custom user tuning map\u003c\/li\u003e\n\u003cli\u003eMap 7: progressive water\/methanol tuning map\u003c\/li\u003e\n\u003cli\u003eMap 8: valet \/ low boost map\u003c\/li\u003e\n\u003cli\u003ePiggyback tuner — boost is controlled through the sensor network and CANbus, with no ECU flash\u003c\/li\u003e\n\u003cli\u003eBoost-by-gear control, so timing and boost can be pulled out of 1st and 2nd for traction\u003c\/li\u003e\n\u003cli\u003eLive gauges, datalogging, and fault code reading and clearing\u003c\/li\u003e\n\u003cli\u003eNot VIN-locked; roughly 20 minute install and fully reversible\u003c\/li\u003e\n\u003cli\u003eCARB-approved version available on the Gen1 fitment\u003c\/li\u003e\n\u003cli\u003eNot compatible with hybrid or mild-hybrid equipped vehicles\u003c\/li\u003e\n\u003cli\u003eJB4PRO is available on Gen2 cars only\u003c\/li\u003e\n\u003cli\u003eJB4PRO board adds direct ethanol sensor control\u003c\/li\u003e\n\u003cli\u003eJB4PRO board adds port injection \/ CPI \/ WMI control via the PnP add-on harness\u003c\/li\u003e\n\u003cli\u003eJB4PRO board adds built-in fuel pressure control for advanced tuning on ethanol mixtures\u003c\/li\u003e\n\u003cli\u003eJB4PRO board adds onboard datalogging memory\u003c\/li\u003e\n\u003cli\u003eJB4PRO board adds additional high-current outputs for extra pumps, relays and solenoids\u003c\/li\u003e\n\u003cli\u003eJB4PRO board adds additional inputs for monitoring external sensors\u003c\/li\u003e\n\u003cli\u003eJB4PRO board carries Bluetooth and memory on the board itself rather than via the adapter\u003c\/li\u003e\n\u003cli\u003eJB4PRO board adds CANbus integration with flash tuning\u003c\/li\u003e\n\u003cli\u003eFree firmware updates for the life of the unit\u003c\/li\u003e\n\u003cli\u003e5-year warranty\u003c\/li\u003e\n\u003cli\u003eDesigned and assembled in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eJB4 tuner in a billet aluminum enclosure\u003c\/li\u003e\n\u003cli\u003ePlug and play wiring harness\u003c\/li\u003e\n\u003cli\u003eJB4PRO adapter for Bluetooth connectivity\u003c\/li\u003e\n\u003cli\u003eFree JB4PRO smartphone app (iOS and Android)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFuel matched to the map: 91 octane minimum for map 1, 91–93 for map 2, 93+ for maps 3 and 4, and an E30 or stronger ethanol blend for map 5.\u003c\/li\u003e\n\u003cli\u003eA smartphone (iOS or Android) for the free JB4PRO app. The Bluetooth adapter is included with both the JB4 and the JB4PRO.\u003c\/li\u003e\n\u003cli\u003eThe correct generation selected at checkout — Gen1 (2016–2019) and Gen2 (2020+) boards are not interchangeable, and the CARB-approved unit is a separate Gen1 option.\u003c\/li\u003e\n\u003cli\u003eOn a Gen2 car running a \u003cstrong\u003estandard\u003c\/strong\u003e JB4 on ethanol, add the \u003ca href=\"\/products\/jb4-fuel-pressure-upgrade-kit-b58-s58-b48-supra\"\u003eJB4 Fuel Pressure Upgrade Kit\u003c\/a\u003e for direct fuel pressure and fuel trim control.
