what happens?

I know the stock is sending narrow band o2 readouts to the ECU, but if you change the sensor that reads wideband, does that effect how the ecu runs?

if so, better or worst?

Trying to decide between plx and aem uego wideband and this question poped in my head.

I'm sure nothing happens, but curious to see what you think. maybe it'll run better or you could actually tap a $50 a/f gauge and it'll read wideband... lol just maybe.

 

Your ses light will come on. I dont know about you but that bugs me, Even if I know why.

I was just thinking about putting a bung in the down pipe and running the wideband off of it and leave the stock o2 in there. Would that work?

Although the AEM UEGO wideband has a 0-1V output, that signal does not simulate a narrowband o2 sensor output. A narrowband's signal oscillates when your ECU is running closed loop. The AEM's signal will not. I'm not sure about the PLX.

The best thing you should do it just have an extra bung welded in your downpipe and keep the two systems independent of each other. The stock o2 sensor has a heater circuit that the ECU controls as well.

 

The Innovate products WORKS carries have the capability of converting the wideband to mimic a narrowband signal that keeps the ECU happy.

 

BTW, the life of the sensor will vary depending on placement. Since a wideband has its' own heater, you don't need to place it that close to the engine. If I were using the front o2 sensor location, I'd just keep it in there long enough to get my tuning done and then take it out.

 

i have a question what if i have a cell fix(buschur racing) in the stock second o2 sensor and just remove the sensor and screw in the wideband, would i still get accurate enough readings to tune with and would the cel stay off?

thanks

oh yeah i am running cat delete , and the wideband is a utec tuner wideband

 

If you're running catless, then having the wideband in the stock rear o2 sensor location will be fine for accurate readings. Does the UTEC tuner wideband simulate a narrowband signal?

 

^^^^ thats a good question i dont know i just got it and im studying up on it before i install it is the tuner plus the expensive one it may. i really have no clue
