I am looking to purchase a wideband setup for my car, but my question is, are there any manufacturer's that make a wideband sensor that has a narrowband output also? This would be so that I don't have to weld another bung into my downpipe, and still keep the stock ECU happy.

 

im pretty certain most of them nowadays have that capability. the AEM and NGK units for example.

 

lc-1

 

I use a techedge unit.. i think all there units use simulated narrowband outputs...0-5v

they have a guage that shows a sweeping A/F along with the #'s showing like the link i gave to.

 

it doesnt come with a narrowband, it is a wideband 02 sensor, it does come with a wire that you wire into the 5v reference for the ecu

 

uhhhh, i have one. it can be a narrow and a wideband sensor. i ran it this way on my 6 port turbo

 

you could also keep the stock O2 sensor and just get a bung welded into the exhaust for the wideband.

 

I'm using the ZT-2 with simulated narrowband output. I have the switching point set a tad bit richer to get slightly better fuel economy in closed loop.
