right normal lambda probes operate within certain parameters under a closed loop inside the stoichometric rule (roughly 14:1) and give an output voltage. However they cannot provide an extremely accurate air/fuel ratio which is necessary for control while tuning. Wide band sensors use a different method of air/fuel measurement which is more accurate and can work out how far from the stoichometric rule that the ratio should be even when the readings are extreme
Correct?
You can still keep a rough idea on what air/fuel ratio you have with a narrow lambda probe. Obviously if you run too rich you bore wash, and too lean you overheat.
Anyway i only asked about gauges lads, peace

Looks like you did some searching on the internet. Although you should have done that in the first place, I commend your effort. However, I still take issue with the notion that a narrow band 02 sensor (or an a/f guage with a narrow band) provides anything useful above 300 r.p.m.

Nobody ever said you were unintelligent - just uninformed. We were all uninformed once so that isn't really a problem - this place is about learning afterall. The problem occurs when you provide information as if its true when you are not sure. One idea might be to just say "I think" before your statement. If you say, "I think a a/f guage can be useful for turbo applications", I would not feel very sorry for the guy that went out and purchased one because of your statement.
Best regards.
