Okay well I bought the AEM UEGO Wideband from the group buy on here, I am very happy with it. Actually I bought 5 of them and looks like I will be buying more since more people want them over here. The thing I didn’t like is it wasn’t supplied with a Gauge Pod or Holder so I went out and bought a 52mm One. You can see in this PIC everything the Wideband Meter kit came with: You have the Bosch Sensor, The Harness for the Sensor (which is long as hell), The Wideband Meter, The harness for Power, Ground, and data logging outputs, and my gauge holder I bought for 12 bucks or so). What you can’t see is the Bung that is required to install the Sensor, I had misplaced it.

1. Disconnect the Negative Battery Terminal since you will be messing with electrical stuff.
2. I decided I would mount my sensor in the Straight Pipe, I recommend this for many reasons, one of which is you can share with someone else if they need a tune…it makes a good package deal if you ever sell the wideband and most importantly it is out of the way. Other ideas are the down pipe or Turbo outlet pipe. SO you need to Jack the car up and take out the Straight Pipe

3. Once the straight pipe is out, you have to install the bung in it..best way is to drill a hole the size you will need for the sensor

4. Then since you are going to be welding a bung on the hole, sand it down so it is nice and smooth:

5. The place your Bung on top of the hole and weld it in place, then cool it down before going any further or trying to screw in the sensor.

6. Then once it is cool, put the Straight Pipe back in and install the sensor…no pic of this but you know what to do.
7. Then you need to run the Harness to the Sensor from the inside of the car. What I did was ran it through the shifter. You have to cut through the rubber Shift boot and push the wire through.

8. Its now a good idea to test fit your Gauge, I like it on the right side since my right eye is my strong Eye…Then hold both harnesses up to the Gauge, The Sensor Harness and the Power/Ground/Datalog Harness and see how much slack you are going to need for the harnesses exposed and running to the Meter. Don’t secure the gauge yet.

9. Now zip tie off as much of the Sensor harness you will not need and get it tucked up and out of the way. You can now concentrate on the Wires Harness. This is really easy, if you are not hooking up and data logging software it is just a power and ground wire. I ran the Power and Ground to the same wires as my Turbo Timer. Splice in, Twist the wires together, Solder the wires together, and tape them up nice and clean. Sorry this pic I just couldn’t focus, this is before I taped the wires up

10. Now all you have to do is tuck all the wires away, secure the gauge pod somehow. I used double sided tape for now, and start it up. Here is a pic of the installed unit.

Next up, 550cc injector install

very nice write up! Nice action shot of the welding too!

Does it need to be that far downstream?

No shocker in this one???:biggthump

Is that a Megan gauge of some kind in the last picture? If so, what's your opinion of them?

Good writeup, by the way!

I put my sensor in the same location, if I remember correctly the instructions said 36" from the head, somewhere around there.

nice write up man. who ever sold you those widebands hooked you up... :P

gottabfast - actaully I found out today it should be 24 inches at least from the Turbo...

Rittmeister - if you mean my boost guage, that is an ALLtechni Guage..nice stuff..thye sell them at the APEXi store here..

Sco0terzsl - That makes sense to me brother.

slamed150 - Yeah man thanks for the great deal..they are all installed already and a few more people want them...

for a second their i had to remind myself that ur in japan..nice pics and write up..will prob. be a sticky

LOL was it the steering wheel location?

Cool write up!

My brother must have gotten in on the same group buy. I was home over Christmas and helped him get the test pipe part hooked in. Looks like he found this thread somwhere else and followed it ;)

I have the write up on Zilvia, B15, and here

Thats what I kindof figured. :)

Looks great D! Man, you got a lot going on with the car, huh? I'm doing stuff too, hopefully will be done by summertime. :)

How is this wideband working for you? I just picked one up and will install this weekend. Nice write-up by the way.

Moved to: Technical Information Library

Mr Sentra - Thanks Marvin!

Rev1 - Hope it helped you out...how did the install go?

RYAN_S-14 - Cool Mr Mod Man :tongue:

Install went great, I ended up using a larger hole than you show on your writeup though. If you look at the bung, there is a "stepped" end. I made the hole large enough for that to countersink down in the exhaust. I assumed that, so it may not be correct.

Overall it's working great, great enough to find out about a lean condition up top. :( I guess that's why we get these.

i bought one of those too ,but i was thinking can i install the sensor into the hole that is already on the downpipe?(the narrow band 02 sensor hole)

You can but from what I have heard it should be further down..how close is the hole in your DP to the Mani?

I think people put them farther down the exhaust to prolong the life of the sensor.
