Description
Get powerful performance gains without permanent modifications using the Burger Tuning JB4 Tuner for the Ford Ranger. Designed as a fully reversible plug-and-play solution, the JB4 delivers up to 50whp and 70wtq on stock vehicles with zero impact on factory ECU flash or warranty.
The JB4 connects to two easily accessible sensors in the engine bay and uses real-time CANbus integration to remap boost, timing, and fuel delivery based on live engine data. This advanced tuning method retains stock drivability and safety features while greatly enhancing acceleration and turbo responsiveness.
Unlike basic performance chips, the JB4 reads key ECU parameters such as pedal and throttle position, air/fuel ratio, timing advance, knock, and more—then adjusts performance dynamically. It’s preloaded with up to 8 performance maps for different fuels and modification levels, including E85 and race fuel support. Boost by gear, map switching, and datalogging are available via optional smartphone connectivity.
No VIN locking, no permanent ECU flashing, and the unit can be removed and resold at any time. It’s discreet, safe, and backed by a 5-year warranty. Installation takes just minutes with no tools or cutting required.
