AEM UEGO wideband wiring

Re: AEM UEGO wideband wiring
I used an "add a circuit" under the dash that allows you to add another fuse off of one currently there. The white wire is for the signal going to an EMS, right?? If so, I wired that to an open spot in my ECU so that my Neptune could pick it up. Need to extend the wire.

Re: AEM UEGO wideband wiring
solder a wire on a 10a fuse and find a switched power slot under the dash.
if you grind away a tiny bit of the plastic on the top side of a slide in fuse you'll have enough surface area for a good solder provided you use flux for a quick fuse

Re: AEM UEGO wideband wiring
hmm
anybody have any pictures of there setup?
i have the same aem wideband (currently not installed) but im going to run it separate from the oem o2 sensor

Re: AEM UEGO wideband wiring
i just installed mine today
if you don't have running lights and fuse 16 is blank, take a spade off the hot side to an inline fuse holder then to the wideband
just in case anyone is searching in the future i mean fuse 16 for a 94-97 integra

Re: AEM UEGO wideband wiring
I finally wired mine up today, this is what i did. I got this fuse thing from discount autoparts and soldered my power wire to the fuse holder that i put in a spare fuse slot under the dash. then i put the ground behing the steering wheel.

Re: AEM UEGO wideband wiring
According to the AEM manual here: http://www.schnitzracing.com/manuals/AEMWBK.pdf you can set the configuration to the UEGO to P4, and use the white wire to plug into D14 of your ECU instead of your normal Narrowband O2 sensor.
HULOG should capture what the ECU is reading (since the reading will look like a normal nbo2 sensor to the ECU) and Crome Pro (or many of the other free softwares) should be able to plot that for you.
I'm about to try this today.

Re: AEM UEGO wideband wiring
Thread is old but I'll toss my hat in, having an AEM gauge type UEGO..
The white wire is a simulated analog 0-1v output, I would only hook uo that wir e if you're using a stock ecu and it needs the signal to not throw a cel/run like ****.
There's another loose wire that's a full 0-5v output. That's what gets connected in place of the oem o2 signal and the stock ecu will read 0-5v, assuming it's chipped. Your tuning software of choice should have a dropdown menu of o2 scalars. Select AEM and now your ecu will monitor real time o2 data and allow you to datalog the o2 info along with everything else.
There's no point in having a wideband if you can't connect it to your EMS of choice and monitor it as you definitely can't tune **** with a stock narrowband gauge.
Some engine management systems will even self tune the fuel map based off of the widebands 0-5v signal hooked up to it, you simply input an air fuel or lambda target value and as you drive the ecu will build a fuel map on its own.

I'm going to hook my AEM up to D14 and put it back into P0 mode (normal wideband 0-5v) for datalogging.
Having it on D10 doesn't work for Freelog or Crome anyway, and having it in P4 (simulated wideband) mode doesn't seem to help with that.
I have to say though, having the 02 sensor enabled is performing some impressive corrections during part-throttle driving, compared to disabling it (with the AEM connected as a narrowband simulated).
Going to just disable it though. Thanks again.
