Having trouble with AEM wideband

[s13drft89]

Hey, Well I got my wideband installed, but for some reason it reads only 13.4-.5, I had the car tuned prior to this. I also tried to mess with the Safc a bit for instance around 2k rpm it was reading 13.4 I stopped and dialed something much richer on the safc and still reads 13.4. Now do I have it hooked up right? I got the black to negative, red to positive, and then the bosch sensor hooked up. But next to the black and red wires theres other ones, not sure what they are for I believe one was blue and white. Iam not sure if this is the narrowband or the UEGO controller. any help would be appreciated thnx-Ricky

Sit at idle, look at the wideband, then adjust the idle to pig rich with the SAFC...see if you notice the difference on the gauge.

I also tried that, I turned it all the way to +50 (car idle like crap) but wideband didnt change much maybe stayed closer to 15.3 rather then 15.4. Thanks any other input would help

Damn...lol. Did you have to calibrate the O2 sensor? I know on the LM1 I had to calibrate the sensor.

[s13drft89]

What do you mean calibrate? sorry not sure what you mean by it. But when I was searching i found that you had to replace your stock o2 sensor with the aem one, kind of confused about that. For the wires there are four Red, Black,Blue, and I believe White. I heard the blue and white one are for the uego or "tunner". thanks for your help WD-Ricky

This is the downside to the AEM, and many other, wideband unit. There's no sensor calibration function, so if your sensor is a bit off, or as it wears with age and the output changes, the monitoring device has no way of adjusting for this.

Innovative widebands FTW.

For about $35 you can purchase a new sensor from your local VW dealer. Ask for the late model jetta sensor (can't remember which year, but I know it's post 2000), bosch unit. This is what LM, AEM, Zeitronix and a multitude of others use.

So basically your telling me that the oxygen sensor is no good? I think thats what your basically saying, (not in a sarcastic way). On the o2 sensor theres a little unit or little relaying looking thing that connects in between the o2 and the wideband, does that usually come new with the sensor? thnx-Ricky

Do you know if PLX has this problem?
