Power gains of up to 100hp and 120wtq to the wheels on a stock vehicle

This plug and play tuner attaches to two easy to access sensors in the engine bay and works with your factory ECU tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. It features a 64mhz processor allowing sensors to be sampled 800 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance.

The default setting is 3psi over stock and boost can be adjusted using a BMS data cable or JB4 Mobile adapter. We've measured stock boost on the Raptor at around 15 psi peak. Raising that to 18psi peak really wakes up this heavy truck!

Installation is very discrete and unlike flash remaps it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged. Compatible with all driving modes.

JB4 adds functionality with a plug and play OBDII CANbus connection allowing the JB4 to take in critical engine data directly from the ECU. Including pedal position, throttle position, timing advance, fuel trims, air/fuel ratio, engine knock, and much more. Other tuners without CANbus are not able to even monitor this critical engine data no less incorporate it real time in to their tuning algorithms.

The JB4 also features multiple maps based on this expanded engine criteria, smoother partial throttle performance, additional engine safety systems such as lean run or over boost, more advanced logging for those wanting to experience with different fuels and E85 mixtures, boost by gear to improve traction, the ability to read and delete fault codes, and much more to come via free firmware updates. Made in USA. 5 Year Warranty.

Harness Options:

Vehicle fitment

• 2011-Present Ford F150 2.7L & 3.5L Turbo EcoBoost & Powerboost

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

Sensor arrangements are vehicle specific, so while our model year guide gives common applications, there are some 2017-2020 vehicles that use V1.5 harnesses, some 2021+ models that use V2 harnesses, etc. Check your vehicle prior to ordering.

Part F-150_JB4 is CARB Approved Under Executive Order (EO) No. D-744-5 for 2015+ Ford F150 & F150 Raptor 2.7L and 3.5L Turbo engines.

Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. Separate JB4 Mobile app purchase also required.
