Aem Wideband Sensor Installing

[paulr33]

the exhaust temp makes sense

but thats the first ive seen a 1 meter limit

how far away would the std 02 narrow band sensor be?

you reckon its 1m?

[KiwiRS4T]

I don't know about Tech Edge but the Innovate wide band sensor has a narrow band emulator with a seperate wire which is outlined in the instructions so you can just plug in to where your original O2 sensor was. Otherwise you will have to go to a welder and get the spare bung that came with your unit welded in to the front pipe. There is a special spanner available to get the O2 sensor out - you may have to get one or get a workshop to undo it for you.

Well supposibly the factory narrow band can be mounted close due to them not being affected by heat as much.

Here is what it says regarding fitment:

Remember however that placing the sensor too far to the rear of a vehicle will often over-cool the sensor, and too close will over-heat the sensor. Turbo vehicles are even more difficult as there are larger variations between boost and non-boost operation.

Turbo installations require the sensor to be positioned even further from the exhaust valve. Initially try 1 metre distance from the turbo outlet. Don't be fooled by manufacturers placing narrowband sensors right after the turbo outlet, wideband sensor will overheat under boost.

I think I might just install it prior to the cat location (even though I would love how easy it would be just to put it into the factory location). I have a exhaust temp sensor in the dump pipe and under full noise the temps really get up there.

Ive got an innovate lc-1 too close to the turbo, and it throws a code and turns off whenever i give it some stick

[kjb_r33]

I had a Tech edge sensor mounted in the stock ones position, it lasted about 12 months but did die. Wide band sensors cannot handle the same heat that the narrow band ones can. New one got mounted just before the cat in the front pipe. Current ones been going for about 2 years, no problems.

[KennyR33]

the aem windeband should be placed 36" from the turbo outlet according to the manual.

36" is 0.9144 m

[PM-R33]

Cool cheers for confirming all that guys. Looks like before the "cat" it goes.

well you cant place it after the cat if you dont have a decat otherwise the readings wouldnt be very accurate

[KennyR33]

Ive got one more question for this subject

where have all of you put the harness plugg between the sensor and the harness to the gauge? the big connection thingy, i dont want it just hanging under the car :S and how well can the cables handle the heat from the exhaust???

I brought my cable up through the gear lever boot, plugs inside car and it saves running to much of the cable outside and is worth the effort of lifting boot. Just straighten out the lip on the steel plate that holds the boot into place.

well i have the cable inside the car i brought it through the hole under the passanger seat, but the big thing that connects the sensor and the other cable is just hanging under the car and that cant be all that good :S so i need some ideas on where to place it, can i just press it over the heat shield for the cat or is it going to get to hot?

hey guys

I've done a turbo swap and I'm gonna be putting the wb sensor in the downpipe just before turbo for time being which is where the guys who made my downpipe placed the bung. I'm not gonna be pushing it hard with this in place - its purely to see what my fueling is roughly doing in the low load cells whilst I get it to my tuners for the rollin road..

I'll whip it off further down the line and mount it in the downpipe to see how it goes then run the wiring through to the cabin.

I'd also like to get it talking to my G4 link ecu I've got installed so it can do the autotune for the lower load cells as I drive.

[PM-R33]

I ended up running mine in the factory location. I couldn't be f**ked putting it down so far and wanted it ready for my tuning.

The way I figure it is on normal driving there is no way it is doing the sensor any damage (my exhaust temp sensor is right next to it and the temp on cruise is very low). Fair enough on WOT it might get hot for it, but considering they say it has a limit of around 900-1000 degrees, it still doesn't get anywhere near that in my car so it can't be killing it that quickly.

Fair enough it might reduce it's life but if it fails in a years time than I'll consider moving it, for now i'm going to see how long it lasts where it is.

Live life on the edge!

I'm sorry if this sounds retarded but it is ok to install the Bosch sensor directly into the pipe without welding and using a bung?

[Shoota_77]

It does a little bit....

Basically no, you need the weld on bung to have enough thread to screw into. The pie thickness of your exhaust is not enough to hold it.

[CrimsonLey]

Thanks for the reply. where exactly should I mount the whide band sensor? 36" from the exhaust lands on the down pipe.

I'm planning on buying a titanium down pipe. would it be a good idea to install the bung on the titanium down pipe?

[benji-nz]

For me I put the bung in my decat pipe, nice and simple.

If you're going to do it you may as well do it properly and put it as close to where is recommended by the supplier/manufacturer.

You may need to get a different bung to weld on to a titanium pipe. I'm not sure if mild steel or stainless can be welded straight onto titanium but someone may be able to answer that?

or if you don't want to weld a bung for whatever reason.. get this:

[CrimsonLey]

Thanks for the info, mate.

My issue is that I want a titanium exhaust so I'll have to get a Ti bung.
