Description
Unlock the full performance potential of your Ford Explorer with the JB4 Tuner, the ultimate plug-and-play solution for turbocharged EcoBoost® engines. Designed to deliver up to 100hp and 120wtq to the wheels on a stock vehicle, the JB4 improves acceleration, reduces turbo lag, and enhances overall drivability—without the risks associated with ECU flashing.
Discrete, Fully Removable Installation
The JB4 connects to two easily accessible sensors in the engine bay and works alongside your factory ECU to safely remap boost, timing, and fueling. Unlike flash remaps, the JB4 is fully removable, leaving your Explorer unaware it is making additional power. Fuel economy remains unchanged during normal driving, and all driving modes—including towing—remain fully supported.
Advanced CANbus Integration
Featuring full CANbus functionality, the JB4 reads real-time engine data from your ECU, including pedal position, throttle input, timing advance, air/fuel ratio, knock sensors, fuel trims, gear selection, and more. This allows the JB4 to deliver smooth, consistent power gains with unparalleled precision. Other tuners without CANbus cannot access or integrate this critical engine data, making JB4 the superior tuning solution.
