Cross posting this for attention.



This picture shows my wideband setup. To the right in the picture is the exit of my exhaust manifold with the factory o2 sensor and it connecting to my test pipe. on the left is the wideband sensor. I'm having some issues and i'm not sure if i ruined my sensor trying to figure out my previous fueling problem or if my wideband sensor is too close to the exhaust manifold and its getting cooked. I'm working on some exhaust updates so if i need to move it, now would be a great time. Is the wideband too close? The setup is a JRSC on low boost.

 

Have you considered moving the wideband into the bung that your OE style narrow band sensor is located ? Your Hondata S300 can utilize the wideband O2 sensor with a bit of wiring... and the gauge can still work.

 

I had not considered that just from some general interwebs searches when i was looking to locate the sensor before. But i would certainly be open to it!

 

You're not doing yourself any favors by having the lambda sensor where it is.

- The joint possibly leaks a little air, generally you want to stay upstream of it.
- The further away you are from the exhaust ports of the engine, the more you increase the transport delay. That's the time it takes for the exhaust gas to travel from the combustion chamber to the sensor.

Just move it to the narrowband bung. You don't need that anymore with the S300.

 

Interesting, a lot of what i was reading was giving me the feeling that I needed it more downstream and closer was not good. But, those were also turbo applications now that I think about it.
