pfc fcon is designed to run with hks fcd !!!! if its e304 then it HAS to have its own mapsesor and if its 3112??? then its a useless no map sensor setup make sure to get the e304 1 with the map and a gcc controller also the plugs are tp18 for gt turbo and tp19 for the little v price around 150£ with map and with no gcc and no fcd !!!!!!!
