Can you use Wideband sensor to give Narrowband signal?

I might be going nuts but im sure i read somewhere that you can take a signal from a wideband sensor and use it to feed the narrowband signal...ie only have a wideband in the downpipe. I seem to remember it being a case of splicing into 2 wires on the wideband sensor.

 

Only reason im thinking about this is that my new single downpipe only has a flange for a normal screw-in sensor, which would mean i need to get a plate welded on to use the standard narrowband sensor. Plus it would mean having to replace a wideband sensor + narrow band (over time).

 

Can anyone elaborate on this...or did i just dream it up?

I think that depends on if you can self adjust your wideband sensor?

Wideband is usually 0-5v depending on AFR

Narrowband is 0-1v, where 0 is rich and 1 is lean (or vice versa)

So if you have a controller which you can recalibrate, like the innovate LC1 for example, you can actually configure it to give a narrowband changover output at whatever AFR you desire.

 

MORE FUEL!:D

Cool thanks!!!

 

My only question now is can you split a single analog output channel to feed to readers. ie. LC-1 has 2 analog outputs. I would have one running in narrowband, going to the ECU to replace the old standard sensor...i would then want to feed my Datalogitz AND a guage. Can i just split the wire on one of the analog outputs and feed the guage and the datalogger or will doing this make the signal too weak?

If you buy the Innovate gauge this connects via the serial interface on the LC-1, leaving the other analogue out to do what you want with.

thats only with the XD-16 gauge which is exp[ensive...i was only going to get the other (new) innovate gauge thats cheaper but runs off analog signal and not serial...

Oh right, hadn't seen that one before. Not sure if it's a good idea having two things hanging off a single output - there's probably no real way of telling if it'll work without trying it. I presume your data logger hasn't got a serial input?

Yep, I've used the AEM Narrowband simulation output in the past to feed the ECU.

Very well it worked, too.

 

What exactly is the AEM narrowband simulation? I've read up some stuff that states you can change the calibration of the output but I don't know if that means the signal output or the guage output. Does the AEM UEGO have a 0-1v stock O2 sensor style output?
