aem wideband install
i was thinking about installing my aem wideband tommorrow and i was wondering
how hard it would be... and can anyone find any write ups on this because the "search" button didnt give me crap oh and i heard i need a new bung put in my exaust system before the cat.... is this true??? thanks for all the help |
wow 14 views and noone knows anything or has a comment?? :lol:
its going to be a long night |
The actual gauge install should be quite simple and straight forward, but unless you have some tack welding skills of some sort, you will have to pay to have the 02 Bung professionally installed.
|
1. Find suitable place to mount it the gauge
2. Get bung welded in before the cat. 3. Put o2 sensor in bung. 4. Run harness into car via firewall rubber grommet (metal coathanger might help with this) 5. Hook up harness to gauge. 6. Use an Add-A-Circuit for a 12v power source that comes on when the key is turned on. 7. Make a ground on the car somewhere. 8. Make everything look clean. 9. Take it for a test drive. 10. Have a drink and admire the work ! :twothumbs |
looks like its going to sit here and look pretty until i decide to get a bung welded in then :lol:

Go to an exhaust shop. It'll take like 10 minutes max to do, and will only cost a few bucks. All they need to do is drill a hole, and weld the bung on there. You can put the sensor in and zip-tie the harness off to the side for the ride home, where you can finish the install.

If you have a digital camera catalog your work and be the future hero of all wideband installers!

I gotta ask, I've searched and found multiple threads on "wideband installs" but no solid answer to my question. Several threads say the bung has to be welded in before the cat, so: Is there a "best" place to put it? Like how far down on the downpipe is the best place for it? Does it need to be on the top / bottom / side / doesn't freakin matter just stick the damn thing in / etc / etc / etc. Does anyone have a pic of the bung and sensor installed? Thanks. :cssNET:

If you have hpt, turn off the rear o2 sensor and put it in there.

it should say in the instructions where and how to mount the bung. I believe it's at a 15 degree angle so that fuel won't get trapped inside it. Theres also measurements on how far down to mount it

Thanks for the responses. I just didn't want to get the wideband and stick it in and then order exhaust and have to redo everything because I put the bung in the wrong place.
|
it needs to be at least 18" after the head and before the cat. it also need to be at least at a 10* angle higher than being horizontal, (ex. 2 o'clock position or higher).

You will have to knock out the inside of the cat if you mount it in the rear o2 sensor port.

^^^^^ poss in the states there emission regulations are different and they don't monitor the converter efficiency like in Canada

When I installed mine in my cobalt I just unplugged the rear o2 sensor covered it and tied it up to the frame for later use. I then screwed in the wideband o2 sensor (you need a big effin wrench btw...i think 22mm). Then ran the wire up the engine bay, through the firewall on the driver's side. I make a makeshift gauge cluser in the left cupholder so nobody really saw the gauge but me. I ran the power to a fuse in the fuse box on the passenger side. Grounded it to a metal piece nearby and boom, done. I just hate running wires, so it was a pain. Also make sure when you run the wires through the engine bay that its not touching any moving parts or any exhaust or engine parts that get hot. Then you get melted wires.
