For 2014+ F Series N55 motors that have an electronic wastegate. This add on patch allows your JB4 to directly control your electronic wastegate raising the boost ceiling for more heavily modified N55 vehicles such as those using E85 or water/meth injection. Connector is not used on map1 or map2 even if installed. Additional information and directions are posted here: http://www.n54tech.com/forums/showpost.php?p=299688&postcount=539
