ECWI electronic controlled water injection. if that nipple is all you have, you are missing all the electronic controller, wiring, solenoid, and hoses that go with that fitting. water injected closest to the exhaust ports gives the best bottom end. usually the top screw is closed with water injection and the bottom screw is open a bit. if you don't want to buy the whole system, just remove and plug that nipple hole. open the top screw just a bit for the best bottom end performance you are going to ever get without ecwi
