Thread: Aem Uego wideband

What I normally do is just get power from the ECU IGN power source and ground the wideband to the sensor ground right at the ECU connector.

You can run the ground all the way to the intake manifold if you wish, but in most cases you should be fine just grounding it at the sensor ground at the ECU.

^^^ That's what I did, and it works beautifully. I did notice however that Nismotronic reads a few tenths above what my gauge is reading at any given time.

I tried to adjust it out, but tt appears as though the voltage offset (if you select custom) only allows you to use whole volts. Is this correct, or was I just not paying attention?

Also, is there any chance of hurting the ECU if I have multiple gauges tapped into that power/ground source to the ECU? I have two others that I need to get powered up, and I was just going to put a Euro Style terminal inline with the ign power and ground.

I believe you can use decimals, not just whole numbers, but I will check that out and get back to you on that!

As far as the current draw on the ECU, for the most part everything that you have connected to power/ground will be very little draw so it shouldn't be anything to worry about at this point.

Thanks for the info. I'll have to check it out when I do some more break-in/tuning later. It's looking like I need another alternator before I can do any of that though... ugh.

I was considering getting the 95 Amp one offered by NAPA. Anyone know if the extra 15 amps would affect anything?

Thanks.
