Wide Band Vs Narrow Band O2
My mate has two o2 sensors on his o2 eliminator,one is a Motec wide band o2 sensor, and the other is a 4 wire NTK narrow band o2 sensor next to the Motec.
As he goes WOTs on his car, Motec WB sensor reads 11.6 air fuel on its display while the NTK narrow band reads 0.69volt on his Jumptronix. He has checked all wirings and nothing appears to be amiss. The NTK appears to be normal at vacuum and low boost but will read between 0.65 to 0.79v at WOTs above 20psi boost. Moreover, the NTK has only about 4000 miles on unleaded fuel and still quite responsive.
From readings off NTK, the NTK is totally off as oherwise he could have blown his motor long before. To verify that, he checked his spark plugs and all appeared rich.
The NTK seems to be crap when working at high boost. What is your view on this?
