Description
The Burger Tuning JB4 EWG Add-On Connectors allow your JB4 tuner to directly adjust wastegate duty cycle (WGDC), delivering greater tuning flexibility and improved performance. By taking direct control of the wastegates, the JB4 can more precisely target boost levels—especially beneficial for modified vehicles experiencing boost control issues.
With this upgrade, you’ll experience faster turbo spool-up, sharper throttle response, smoother gear changes, and an overall more responsive driving feel. This add-on is ideal for drivers seeking maximum performance refinement from their JB4 setup.
Note: JB4 units shipped before October 2019 may require the updated 2580 master chip if the EWG wires trigger a startup fault code.

What is an EWG Add-On?
An EWG (Electronic Wastegate) Add-On Connector integrates with your JB4 tuner to control the electronic wastegates in your turbocharged engine. By adjusting wastegate duty cycle directly, the JB4 can fine-tune boost delivery for smoother, more powerful acceleration. This upgrade is particularly valuable for vehicles with aftermarket modifications where maintaining consistent boost targets can be challenging.
