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.

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?

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.

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.

Ive got one more question for this subject :blink:

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.

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!

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?

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?

    • Hey y'all! I'm curious about how y'all go about widebodying your cars. I noticed that when running a square setup, my front wheels are a bit more tucked in than my rear wheels. Not by much, maybe 5-10mm. This leads me to wonder - when I widebody, should I use narrower front flares and wider rear flares? I found a set of 40mm rear flares that I really like, and was thinking of pairing them with some 18mm front flares, but I don't want the car to look strange. How have others done this? Note, I'm in a sedan. Thanks!
    • And if it was anything other than an auto tranny part, it might be a problem. But seeing as all auto trannies belong in the recycling bin, it's fine.
    • I have an R32 Fenix rad. It is good.
    • All the schemas I can see, indicate your typical setup of ATF 'cooler' (read: heat exchanger) in the bottom radiator tank..ie; https://nissan.epc-data.com/stagea/wgnc34/5413-rb25det/engine/214/ ...but I can prattle on a bit here. These trannies have a thermistor in the sump ~ the TCU reads this and 1. bumps the line pressure up when the ATF is 'cold' and 2. prevents the TC lockup clutch from operating, until the ATF comes up to minimum operating temp (keeps the ATF 'churning' through the TC so it heats up quicker) -- trigger point is around 55C. In these conditions, the engine coolant temperature rises faster than the ATF temperature, and also helps heat the ATF up, which is why it's best to think of the in radiator tank setup as a heat exchanger ; the heat can flow in both directions... ...with these trannies, the 'hot' ATF comes out the front banjo bolt, flows through the cooler/heat exchanger, and returns to the box  via the rear banjo bolt. This gets a mention, due to the wildly different opinions wrt running auto trans fluid coolers ~ do you bypass the in radiator tank altogether, or put the cooler inline with the in radiator tank system...and then, do you put the additional cooler before of after the in radiator tank system?... ....fact is the nominal engine operating temp (roughly 75C), happens to be the ideal temperature for the ATF used in these trannies as well (no surprises there), so for the in radiator tank system to actually 'cool' the ATF, the ATF temp has to be hotter than that...lets say 100C -- you've got 25C of 'excess' heat, (slowly) pumping into the 75C coolant. This part of the equation changes drastically, when you've got 100C ATF flowing through an air cooled radiator ; you can move a lot more excess heat, faster ~ it is possible to cool the ATF 'too much' as it were...(climate matters a lot)... ...in an 'ideal' setup, what you're really trying to control here, is flash heating of the ATF, primarily produced by the TC interface. In a perfect world, wrt auto trans oil cooling, you want a dedicated trans cooler with builtin thermostatic valving - they exist. These should be run inline and before the in radiator tank system ~ when 'cold' the valving bypasses the fin stack, allowing the ATF to flow direct to the in radiator tank heat exchanger, so it works 'as intended' with helping heat the ATF up. When 'hot' (iirc it was 50C threshold), the valving shuts forcing the ATF through the cooler fin stack, and onto the in radiator tank heat exchanger...and you sort of think of it as a 'thermal conditioner' of sorts...ie; if you did cool your ATF down to 65C, the coolant will add a little heat, otherwise it works as intended... ...the 'hot' ATF coming from the front bango bolt, is instantiated from the TC when in use, so all/any flash heated oil, flows to the fluid-to-air cooler first, and because of the greater heat differential, you can get rid of this heat fast. Just how big (BTU/h) this cooler needs to be to effectively dissipate this TC flash heat, is the charm...too many variables to discuss here, but I just wanted to point out the nitty-gritty of automatic trans fluid coolers ~ they're a different beastie to what most ppl think of when considering an 'oil cooler'... /3.5cents   
    • Been a busy but productive day. Axle and hubs acquired. All fitted up after a bit of modifying. Need to sort out wider mudguards and running light reflector covers but other than that the trailer is gooood to go !!
