    http://www.gearhead-efi.com/Fuel-Inj...1&d=1380313658. This picture you posted of the narrowband in the header. PUT the wideband in the other header. Doesn't help that your narrowband is non heated I missed that part. Your problem is not injector data. Your narrowband does not like the overlap of the cam and being a cold sensor. It shows that when you put it in open loop it runs ok. That means your ve tables and injector data is close. When it goes to closed loop the narrowband goes crazy and the fueling goes downhill.
