JB4 EWG Add On Connectors (PAIR) for Kia Stinger/G70 and Infiniti VR30 Q50/Q60

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.

Note JB4 models shipped prior to Oct, 2019 may also require an updated 2580 master chip if EWG wires trigger a startup fault code that clears until restarted.
