What is a JB4?
The JB4 is the industry’s leading plug-and-play tuning solution for turbocharged engines. By integrating into factory sensors and utilizing CANbus data, it delivers intelligent real-time tuning and unmatched power gains. Backed by over a decade of ongoing development, the JB4 remains the gold standard for those who want serious performance without compromising drivability or safety.
Choose your sensor
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
2) V1.5 Harness: One V1 sensor, one V2 sensor
3) V2 Harness: Two V2 sensors
4) V3 Harness: One V3 sensor, one V2 sensor
Included in the Package:
-
JB4 Tuner with billet enclosure
-
All necessary harnesses for plug-and-play installation
-
Optional JB4 Bluetooth Connect Kit (sold separately)
