EW G Add On Connectors

The Burger Motorsports EWG Add On Connectors provide enhanced tuning capabilities for your JB4 system by directly interfacing with the wastegates. These connectors enable the JB4 to add or subtract wastegate duty cycle (WGDC), offering greater flexibility for performance tuning. This is especially beneficial for modified vehicles struggling to achieve proper boost targets. Installation involves connecting the wires to the JB4 harness, updating the JB4 firmware and settings, and attaching them to the wastegates. The product offers several key benefits, including improved boost response, faster turbo spool up, smoother shifting performance, and a more refined overall driving feel. User reviews suggest a noticeable improvement in car feel, particularly during shifting at higher RPMs, with some users reporting fixed overboost issues. A note for users with older JB4 models: those shipped before October 2019 may require an updated 2580 master chip to avoid a startup fault code. This chip is available separately. The product is available for various vehicle platforms, including the Kia 3.3t, Kia 3.3t JB4PRO PNP, Infiniti VR30, and Mazda 2.5T V2, with specific installation guides provided for Kia/Genesis and Mazda applications.
