Description
The Burger Tuning JB4 Tuner for the 2019+ Ford Ranger delivers substantial gains of up to 50 wheel horsepower and 70 wheel torque on a factory truck — all without the risks of ECU flashing. Designed for the 2.3L, 2.7L, and 3.0L EcoBoost® engines, this tuner integrates seamlessly with your Ranger’s factory ECU for optimized boost, timing, and fueling, reducing turbo lag while maintaining factory-like drivability.
Unlike flash tunes, the JB4 installs with a discreet plug-and-play harness and can be fully removed without a trace. With CANbus OBDII integration, the JB4 monitors and uses real-time ECU data such as throttle position, air/fuel ratio, engine knock, fuel trims, gear selection, and more — ensuring smooth, safe, and powerful performance.
Preloaded with multiple maps for pump gas, race fuel, and ethanol blends (E85), the JB4 also allows boost-by-gear control for better launches, fault code reading/clearing, and custom tuning via your smartphone.

What is a JB4?
The JB4 is a next-generation plug-and-play tuning system for turbocharged vehicles. It intercepts and optimizes signals between the engine’s sensors and ECU, increasing performance safely and effectively. With CANbus integration, it makes precise, real-time adjustments for power gains unmatched by basic performance chips. Fully reversible, not VIN-locked, and backed by frequent free firmware updates, the JB4 has set the benchmark in turbo tuning for over a decade.
