I would lke to take my teg to the local rolling road to tune this but reading stuff others have posted I need a Wide Band Oxygen Sensor to stop me leaning out the engine too much. Is this the same thing as a Lamba sensor which is what my local rolling road's got?

 

VX o2 sensors are good for widebands, too.

 

they've only got a Lamba sensor there, will this do the same job?

 

Yup, the Civic VX are wideband. Hard to find though. I happen to have one that I'm keeping

 

give it up.

 

I never knew they were wideband
whats it cost new from honda?

 

Lambda and wideband are the same thing for your purposes.

VX O2 sensor is what a wideband O2 controller uses. Alone the sensor is not a wideband unit.

 

OK thanks!
