You can keep your gauges but you will need to get a gauge to moniter the a/f still. Or you could sell your defi gauges and buy aem serial gauge and oil pressure package.

 

Keep in mind that there is the UEGO and their is the Gauge-type UEGO.

I have an older AEM and a separate UEGO. But I have no gauge.

It would be nice to have all signals going to the AEM and then displayed through the serial gauge or the gauge0tech display. But you have to buy all the sensors and offload your Defi set up. May not be very economical.

 

"and I'll list up the 6-in-1 as well which has a wide band controller built in and can display 5 other functions as well."
Reads kind of odd. Just as a heads up:
The 6 in 1 is only a wide band. It will not display other functions like the serial gauge will. Actually, you only connect the white wire(if I remember) into one of the O2 inputs on the EMS.
Also as a heads up, if you run both the serial and the UEGO gauge(I run them both). The illumination of the serial gauge is allot dimmer, and you have to pull the black tint piece out to match the UEGO.

 

losing my mind working on the car all day long putting it back together.

The UEGO is different. The UEGO display only shows the wideband readings. The AEM 6-in-1 is cheaper than the regular AEM UEGO Display and can have a bunch of faces and bezels installed to suit your car. This is not just a controller it is a display as well.

I will have my new stock of AEM stuff coming in on monday I believe and I'll list up the 6-in-1 as well which has a wideband controller built in. So just bear with me before I list it up on my site.

You can get rid of all of your defi gauges with the AEM Serial Gauge if you buy all the additional sensors required (i.e. oil pressure, oil temp, fuel pressure).

If you have the AEM EMS 1052U - AEM Serial Datastream 19-in-1 (can display the wideband output)
If you have the AEM EMS 1052 - AEM 6-in-1 + AEM Serial Datastream

 

I think for the time being I will go with the AEM Wideband UEGO controller/gauge combo. Having some piece of mind is probably worth the $275 considering what everything else cost. Worst case I end up with a dedicated a/f gauge along with the serial or other gauges.

Is it safe to assume the the O2 sensor that comes with this kit replaces the factory O2 sensor and there is some way to connect the factory wiring to the new sensor? I would think there must be a way to tap/convert a narrow band output since that is what the factory is looking for.

 

The O2 sensor does replace the factory one but you don't use the same wiring. You have to run the new wiring up and through the firewall to the ECU.

 

Jano,

The AEM does not have an additional narrow band output. The only one I can think of that does is a PLX devices. Now, the AEM UEGO does have a O2 bung, you can just weld that onto your exhaust(pre-cat). You could also pick up a test pipe, and just have it welded on if you don't want to mess with the factory header(but you loose your converter). Once you have your AEM EMS, you can just replace the O2 one or two input with the UEGO gauge data output.

 

The gaugeless UEGO has narrowband output and I believe the gauge one does as well. So you can remove the OEM O2 sensor and fit the AEM one. You still need some load on the OEM heater circuit to avoid a CEL but you can do thatby leaving the stock sensor connected to the wiring or with a resistor.

Of course if you have an AEM EMS this all become irrelevant.

 

Not sure about the other, but I can promise that the Gauge type doesn't have a narrow band:



But like said above, if you have an EMS, don't worry about it.

 

Thanks guys...I did a little more research and according to AEM's gauge forums, the current 6-1 UEGO gauge can output a couple different ranges of analog signals. The admin there posted the following to essentially the same question as mine -

__________________________________________________ __________
Q - I see it has a 0-5 volt user programable output but does that mean I can program it to on send a 0 to 1 volt signal to the ecu ? and if so how is that done. oh and does the uego have a warning light for lean readings?

A - You can download the UEGO gauge instruction manual here:
http://forum.aempower.com/forum/index.php?topic=16214.0
You should be able to get a better understanding of the gauge by reading manual.
The analog output (0-1, 0-5, etc) is selected by turning a switch on the back of the board.

Since there might be issues other than just the signal (CEL's if not wired right, etc.) I think I will leave the factory sensor alone and have the bung welded in, and clean things up if/when I go with the full EMS. Any guidelines as to where it should or shouldn't be located? I would imagine anywhere in the general vicinity of the factory sensor with enough access for someone to drill and weld?
