I am wondering; the wideband I just ordered has a narrowband output for running a normal a/f guage. Can you use the narrowband output to run your stock ECU's O2 sensor, allowing you to just stick the wideband into the stock O2 sensor's hole and using it to control both the ECU and to datalog?

 

It depends. From researching various units before buying mine, I saw that some have a 0-1 volt output especially for replacing the stock sensor, while others had a 0-1 volt output for running an AFR gauge. The difference was that the one for the gauge was averaged; that being that a lot of the variability was removed from it so that the AFR gauge wouldn't bounce around.

Such an averaged signal would do unknown things with the ECU.

 

be more specific... are you talking about a plx w/b with an autometer type a/f gauge?

and what ecu are you trying to plug it in to??

 

SO you've looked into this before, eh?

Know anything about how the Zietronix wideband figures the narrowband output voltage?

 

I found information here:

http://www.zeitronix.com/Products/zt2/zt2.htm

It says "Simulated Narrowband Output to feed stock ECU".

There you go. It will work fine, ditch the stock sensor.

 

I've had a hand in a couple of different plx set ups...

one with their 4digit display and one using the convertor to use the autometer a/f as a w/b display... both feeding a narrowband signal into a honda ecu.

now both cars are feeding a w/b signal into stand-alones..

 

Thanks Beepy, I can't believe I missed that part of the site!
