N55 JB4 Upgrades

JB4 N55 Replacement Control Board

Update or replace your JB4 control box with the latest options listed below. Note most 2014+ vehicles include electronic wastegates and will benefit from the EWG board. If upgrdaing a previous PWG system to EWG we suggest you modify the JB4 harness by cutting off the black ground & red power wires. Also note the purple MAF harness is no longer used for any N55 application so this can also be cut off the harness to clean it up. Note replacement boards do not include an enclosure and will ship with the latest production firmware. In the case of F series this is OBDII CANbus based firmware.
