Description
The Burger Tuning JB4 for the 2010–2019 Ford Taurus SHO delivers up to +100whp and +120wtq on a stock setup — with even more power possible when running E85 blends or race gas.
This fully CANbus-integrated plug-and-play tuning system remaps boost, timing, and fueling for maximum performance while maintaining factory-like drivability and safety. The JB4 adjusts mapping dynamically based on throttle position, knock control, ignition advance, AFR, gear, and more, allowing for smooth and powerful acceleration without the risks associated with ECU flashing.
With 8 preloaded maps, including stock, valet, and high-performance fuel-specific tunes, you can switch settings on the fly via the optional JB4 Mobile App or BMS Data Cable. Advanced safety protocols ensure boost stays low until the engine reaches safe operating temps, and the JB4 will drop to a safety map if it detects knock, lean AFR, or overboost conditions.
Installation is quick, fully reversible, and leaves no ECU flash footprint — ideal for warranty-conscious owners.

What is a JB4?
The JB4 is the most advanced piggyback ECU tuning solution for turbocharged vehicles. Installed between the ECU and factory sensors, it fine-tunes performance parameters without permanently altering factory software.
With CANbus integration, the JB4 reads dozens of engine data channels in real time, allowing for precise mapping, E85 support, advanced safety protocols, and wireless smartphone control. Burger Motorsports regularly releases free firmware updates, ensuring your tune stays current and continues to deliver optimal performance.
The JB4 is completely removable, not VIN-locked, and can be resold or transferred to another compatible vehicle.
