Permanent Wideband O2 Sensor
Is there a way to replace you primary O2 sensor with a wideband? I've done this before with a standalone, but it may not be possible with the stock ecu.

Technically yes but it's so hot there it wouldn't last very long.

I have a wideband 02 always hooked up (on) in my downpipe about 5 inches from the upper flange. It has been great and reads very accurate for over 2 years now

There is always a way. :) Mostly depends on the desired result and ow much effort you want to apply. ;)
So what's your goal in such setup? Maybe there is an easier way to achieve it. :) |

I could just put in a new AEM but I thought this would be a great time to to learn about all the great things people are doing with stock ecus (if anyone is willing to share basemap please pm me). I already have my wideband wired to the ecu as my primary in my current setup. It would be nice not to have to rewire and add an extra narrowband in the car. |
I believe the most reasonable solution for you is to have linear output from your WBO2 wired in place of stock rearO2 and be used for logging; and simulated NBO2 output from your WBO2 wired in place of stock frontO2. :)

I like this! Great idea. How do I simulate the reading from my WB02 to a NB02? |
What wideband do you have? That's how I have my Zeitronix is setup right now.

I think the AEM has a 0-1v signal to simulate the NB signal. A bit of searching should get you some more info, but basically you have a wire going from the real NB to the ECU. You're going to cut that wire close to the ECU and have the AEM's signal replace the one coming from the stock o2 sensor. In my case I decided to use an on-off-on switch so that I can choose to run either the stock o2 signal (when I go to the track or if my WB dies) or the simulated signal from the WB.

You won't want your sensor that close to the turbo anyways, 10" downstream is about how close you want to get it.

It has a 0-5v signal output
Can I rescale the ecu?? https://www.evolutionm.net/forums/at...ensor-uego.png |
I know in my dsm i used my ugeo to narrow sim works perfectly fine. wired the with wire in to the ecu thru o2 pin. activated narrowband sim in ecmlink.

Both Zeitronix Zt-2 and Zt-3 have narrowband O2 output. Both are adjustable so you can make your engine run in a closed loop (idle or low load) different than stock 14.7 AFR. Either to improve fuel economy or cover up idle problems for moded cars.
