Description
Looking for more power without permanently modifying your ECU? The JB4 is the most advanced plug-and-play tuning solution available for your turbocharged Ford Edge ST (2019+) or Ford Edge 2.0T (2022+). This performance tuner connects easily to two sensors in the engine bay and works seamlessly with the factory ECU to remap boost, fuel, and ignition timing for dramatic performance improvements while retaining stock-like drivability and fuel economy.
Unlike basic tuning chips, the JB4 offers full CANbus integration, allowing it to pull and adjust real-time data from the ECU including throttle position, timing, fuel trims, AFR, engine knock, gear selection, and more. This level of integration delivers smooth, responsive power delivery and enables advanced tuning strategies that adapt dynamically to your driving conditions and fuel quality.

Harness Compatibility – Check Before You Order:

V2 Harness: Two V2 sensors (typically 2017–2020 models)
-
V3 Harness: One V2 sensor + One V3 sensor (commonly 2021+ models)
Be sure to check your intake manifold and charge pipe MAP sensors to determine the correct harness for your vehicle.
