RH9 GTR Posted August 27, 2014 Report Share Posted August 27, 2014 If i select NGK AFX , i cant find any seperate controller for it. Please guide me if the link below is ok and no additional controller is required with it ? Does this unit has a built in wideband controller Â ? Â Can you guys confirm and give me a go ahead so that i can buy the item. http://www.frsport.com/NGK-91101-AFX-Powerdex-Wideband-Air-Fuel-Ratio-Monitor_p_2315.html Quote Link to comment Share on other sites More sharing options...
