AEM UEGO Reliability

[Joe's_GSX]

I am looking for a wideband. I don't want to need to replace the sensor every couple of months. I was reading some reviews about the UEGO and saw that their sensors are not all that great. I see that they use a Bosch Sensor which last time I checked was a good product. Any Ideas? If you have this unit, please post your overall experience with it and how long you have had it? Any problems would be great too.

Thanks Tuners!

I am using the unit. It works great. The only thing that you need to keep in mind when mounting is, you should mount the bung before the flex section. I have been using it for about 6 months and no problems.

Can you tell me more so why I need to mount it before the flex section?

Aem recommends there sensor is mounted 36" from the exhaust ports on turbo car running over 850 degree C EGT. Sensor life is going to vary, I run 114 leaded gas in my car so replacing a $75 sensor every six months is cheap insurance.

You can mount the sensor closer to the stock o2 but over heating the sensor will also cause it to fail early. you must install the o2 before your cat if you still have one?

Most wideband kits on the market these days are using the Bosch sensor. Ironically, even NGK's kit uses the Bosch sensor, and NGK owns NTK (O2 sensor company).

The two most common killers of O2 sensors are leaded fuel and extreme heat. If you mount the sensor where the directions recommend, and you run unleaded fuel most or all of the time, then you should not have any problem with the Bosch sensor lasting you a long time. And as stated above, the replacement sensors will typically cost you $50-$75.

I installed my Bosch sensor roughly 8 months ago, and I haven't had any problems.

I have mine after the flex section because it was about the only place it can be mounted without hitting something. And its exactly 36" from the turbo/Mani. Hope it works fine..

I have mine roughly in the same spot as Boost95. I've only had mine for 2 months though and it seems fast to respond to changes. I'm happy with it.
I must note for any wideband, or any o2 really, that you don't have an exhaust leak before your sensor or you will get erroneous readings.

From my experience, The AEM UEGO has consistently been 2 or 3 points off from most other widebands used at the dyno or other makers.

PLease explain points? You mean full AFR? Like if it should be 13:1 it would read 12:1, please explain.
