Ford F150 EcoBoost / Raptor JB4 Plug & Play Performance Tuner with Bluetooth

Take your Ford truck’s performance to the next level with the Ford F150 EcoBoost / Raptor JB4 Tuner, the most advanced plug-and-play tuning solution available for turbocharged Ford applications. Engineered to safely increase horsepower, torque, throttle response, and overall drivability, the JB4 works with your factory ECU to optimize boost, timing, and fueling without permanently modifying factory software.

Unlike traditional ECU flashes, the JB4 installs discreetly in minutes using factory-style connections to two easily accessible sensors in the engine bay. Since no ECU reflash is required, the system is fully removable and leaves no permanent software footprint. Your vehicle retains factory safety systems while benefiting from substantial performance gains and smoother power delivery.

Advanced CANbus Real-Time Smart Tuning

The JB4 stands apart from basic performance chips thanks to its full CANbus integration, allowing direct communication with your vehicle’s ECU. This gives the tuner access to real-time engine data for intelligent on-the-fly tuning adjustments.

Monitored parameters include:

• Throttle position
• Pedal input
• Ignition timing
• Fuel trims
• Air/Fuel ratio
• Engine knock
• Gear position
• Boost pressure
• Engine load
• And more

This advanced tuning technology delivers stronger performance while maintaining OEM-like drivability and reliability.

Check your sensors to confirm the required harness before ordering!

JB4 systems use one of four different wiring harnesses. You'll need to locate and identify both the charge pipe and intake manifold MAP sensors, generally on the charge pipe leading into the throttle body, and under or behind the plastic engine cover on the manifold directly, to determine which JB4 harness your vehicle requires.

1) V1 Harness: Two V1 sensors, generally found on 2014 and earlier models
2) V1.5 Harness: One V1 sensor, one V2 sensor, generally found on 2015-2016 models
3) V2 Harness: Two V2 sensors, generally found on 2017-2020 models
4) V3 Harness: One V3 sensor, one V2 sensor, generally found on 2021+ models
