Thread: Aem Uego wideband

Anyone have a Aem Uego wideband hooked up to the Nemu? Just wondering if it's the white or blue wire that hooks up to the break-out box. Thanks!

It is the white wire that goes to the break-out box.

Thanks! Got it working! Is it normal for it to display the afr slighty different that what it actually says on the wideband itself?

It depends on where you have the wideband's power and ground.. do you have them grounded to the chassis/engine ground?

Try to ground the wideband to the same place the ECU gets it's ground from.

I haven't tried this yet, but I'll report back when I do....thanks!

People nearly never report back when they do... just sayin'

I hate when that happens! Lol! Seriously though, I haven't got around to it yet, been tied up with the family. I'll probably try it out this week sometime. I'll start with grounding the wb at the same spot as the Ecu. I also read that there is a voltage offset that you can try out too. Are you having similar issues?

Not yet... lol.

I'm doing research to see what is involved with using the AEM UEGO as the one and only O2 sensor through the NEMU board and Nismotronic. There's not a whole lot of information out there on the subject. I haven't even been able to source what wires I need to connect the data logging wires to on my step down harness...

This is very simple to do.

Connect the red wire to the switched power source at the ECU.
Connect the blk wire to the ECU ground.
Connect the wht wire to any of the ADC input channels on the ADC breakout box.

Go to Settings -> ADC inputs and select the wideband you are using in the drop down on the channel that you have the wht wire on.
Go to Wideband Settings and select the ADC channel as your AF input.

If you need to make any adjustments to make the value you see in the software match the gauge.. then use the voltage offset in the ADC section to scale the reading (if you need to!)

I found this thread that explains the process a bit more... Thanks for the info here. It helped me narrow down the search.
