For 2014+ BMW motors that have an (EWG) electronic wastegate. This add-on patch allows your JB4 to directly control your electronic wastegate raising the boost ceiling and tuning flexibility. The new EWG harness has two long wires coming from it. Purple and blue.

The new EWG connections allow the JB4 to directly add and subtract wastegate duty cycle (WGDC) from the wastegates providing additional tuning flexibility. Most useful for modified vehicles that are having problems targeting boost properly and will also improve boost response, spool up, shifting performance, and overall feel.

What are the EWG connectors? They are optional connections that attach the JB4 to the wastegate actuators on each turbo. By attaching directly in this way the JB4 is able to increase or decrease WGDC in a dynamic way to improve boost targeting.

Jun 12, 2020 · A few weeks ago a few were talking about ordering their EWG wires for JB4. Anyone have them installed? What is the verdict? I finally got around to hooking up my fuel wires last night and now looking to the next thing (the wires were built into my JB4 already, I just hadn't hooked them up).

Oct 10, 2024 · The passenger-side EWG wire install is a bitch. I suggest you release the big harness bundle clip above it to shift the harness over a bit for more room and have some long, angled needle nose pliers to release and install the connectors.
