Ditto all the positive feedback.
I'm using the AEM EMS, TwinFire Ignition and UEGO.
One note, make sure you wire it (directly) to the battery for ground AND power.
There WILL be differences between the EMS and UEGO if you do not (mine was a small difference but was annoying just the same).

 

Mine worked fine for 10,000+ miles on my previous car, never had any problems. It would be nice if they read below 10 or above 18, but like someone else said, you really shouldn't be running out of that range anyway.

 

I love mine, I havent had any problems with it. I've had it for about 10 months.

It even says Poo when you turn it on

 

Ha Ha!!! maybe it's telling you something about your driving

 

First thing I said after the install is "It says poo!"

We're so mature

 

ok im a newb to the uego just picked mine up today and im wundering will this replace my stock o2 sensor? if so what do i use to hook it up to the ecu?still running my stock 91 ecu?

 

My only problem is the 10-18 range, but in reality that should really be all that you need.

I like mine, a lot. I have helped put in a LC-1, and after that headache I chose the UEGO. Not ever having to deal with calibration and a simple hook up was all the persuasion I needed.

 

No and yes. Out of the box I don't think it will, but I bet there is some way to do it.

 

No bad experience for me, I hooked it up and it worked.

 

no it wont' replace your stock o2 sensor. drill a hole, spot face, and weld on a bung at least 36" from the turbo. didn't you just ask this question in your own thead? why the **** did you revive an old one too. no need to say you're a newb, we coulda guessed.

 

ummm i revived this thread so maybe more people could help me. then i posted my own question.so no need for the sarcasm cool guy.

 

drftem2- its just how it works around here, special when you post the same question twice
