I just got Aem wide band , when hooking it up do i still leave the stock narrow band hooked up and in its original bung and get a bung welded on to the down pipe for the wide band ?
or
Do i replace the narrow band with the new wideband sensor in the narrow band location .(if i did this wouldnt it throw a Cel because the computer isnt reading and a/f?)

some one please enlighten me, this is my first wide band hook-up

thanks

mike

 

ideally you would weld another bung; im not sure if the aem has a narrow band analog output, if so you could replace the stock o2 and use the output from aem to the ecu

 

any one know if it has the output ?

 

read the directions...

 

directions are kind of vauge , it has a grey wire that is a 5v out put , would this be the one that ties in with the old narrow band wiring ?

 

up

 

no narrow band output should be 0-1v ; 0-5v is the analog wideband output

 

Almost all widebands these days have a narrow band output, I used to have the uego, but I don't remember if it had it or not.

You would essentially weld in another bung and use both. But if you only have one bung, swap out the narrowband for the wideband, and disable your o2 sensor, via a chipped ecu.

 

i already have a chipped ecu with a program from phearable.net but im not sure if his ecu deleats it or not .

 

bump for info !

 

common!

 

Aem uegos have the option for a "narrow band" output.

However, I would simply disable o2 feedback all together (chipped ecu) unless you are running aem ems or an ems with the capability to intelligently use wideband o2 feeback.

 

i just orderd a chip from you (phearable.net) under tony romeo i cant wait to get it , its the only thing i need!

 

John does your ecu's eleminate the stock o2 sensor?

also please ship that thing as soon as you can

 

More then likely he did not. You should have told him to disable when purchasing the ECU. If he did not you can set the voltage on the output to 0-1v. its in the direction on which setting you want. I'm sure he'd send you another chip at a low cost or if your lucky you can contact him before he sends it out.

Your chip will have o2 feedback disabled.
Your order is going out today (Thursday) via usps priority mail.

 

Thank you , i Really appreciate it !

 

Consider that you're going to toast your wideband o2 quite quickly if you keep it connected for daily driving.

 

like how quickly are you thinking ? and how do i know when it is going bad ?
thanks

 

Last I checked, lifespan on the Bosch was around 50-100 hrs. A bit more for NGKs, but not 4 times or anything.

 

life expectancy for most sensors is a loong time, i have had the bosch that comes on the zeitronix on since i got it; over a year and a half ago, daily driven .
Remember that they come stock on lots of VW's, hondas, etc.

The thing is you HAVE to have the wideband controller feeding it voltage at all time when the car is running, if not it will foul rather fast.

 

im having a few problems with it right now , its reading in the mid 14's crusing in vaccume in the morning when on the way to work and it will read then shoot up and the led lights (aem wideband) go back and forth like crazy then it will reset itself and do it alll over again .

i think it might be because i have the power source coming from the radio , im going to change it tonight and see if it solves my problem but had anyone ever had this problem with the aem ? maby it is something else simply wrong or something .

 

It replaces your stock sensor. It says so clearly in the feature set. Didn't you know what you bought? Other people shouldn't be answering if they don't know.

How did you connect the sensor? If you wired it in, I hope you soldered it. The signal wire is very sensitive to resistance. If you simply twisted it together, and taped it up with duct tape, please shoot yourself.

Most likely you simply don't understand what the sensor is telling you.

Car should run rich while warming up and during WOT, high RPMs and loads, and briefly right after a sudden mash on the throttle. Should run lean when there's no throttle but RPMs are above 1300. Should fight back and forth quite a bit around 14.5 during normal driving. Keep in mind that the stock ECU, chipped or not, is not as good keeping up with the sensor as the AEM EMS.

Preflashed chips are junk. They defeat the purpose of getting a wideband. You got a wideband so you could properly tune the engine on a dyno. Anything that disables the O2 is junk and should not be used for dd. The only time you might consider disabling the O2 is if you're only going WOT as in the car is purely for drag racing.

Life expectancy for the sensor should be the same as OEM as long as you're not burning oil, coolant, or running rich. In racing applications the life expectancy is short because you're running rich. But dd should be fine. I hope you know those sensors are expensive and hard to come by. I hope you're not using a chipped ECU or you have oversized injectors and an adjustable fpr.

They lose accuracy after a couple of hundred hours. NGK and Bosch WB are not intended for DD full-time use.

They're meant for tuning maps and then you take it out and disable O2 afterwards.

 

the ''cheap'' bosch wideband comes stock on vw's 1.8t.
I dont think they replace them every couple hundred hours.
After many miles and hours mine still reacts like new.
