Aem Wideband Kit

[benl1981]

After looking a bit into Wideband kits the AEM type seem pretty good.

The best price I can find is about $200US delivered for one that has digital display etc.

I plan on having it go into the datalogit so Im not to sure I need the gauge but some say it may be more accurate so probably good to have. Few questions

1. Does this price seem about right and the kit that most are using.

2. How long do you usually get out of the sensors if not running things overly rich.

3. I would still like to run the narrowband also (for fuel economy on cruise). Do most of you weld another bung in pretty close to the narrowband on your dump pipe? It doesn't have to be a specific distance away from the other sensor does it?

4. Anyone got pics of their setups in relation to dump pipes etc.

5. Where do you usually bring the wires through? Do you feed them through near where the wires come through to the ECU.

6. In the short term I may take out the narrowband and use the wideband for tuning. Is the thread the same on the wideband as the narrow?

Thanks all.

Here is the one I'm considering.

I own one and tune my car on it, ran the car on the dyno lately and AFR's were very similar to the dyno.

I welded the bung in(which is supplied) just before the cat, then the wiring can be fed up through the old cat temp sensor wiring hole

My AEM is fitted in the dump pipe back near the gearbox mount. Bought the wiring up through the gear stick boot/hole and up to the a-pillar where the gauge is. then have the analog out from the gauge wired to my FC-Hako box. pretty good setup, works well

I am going to buy the same unit but I am going to buy it from Australia($30 more) for warranty. Its got 12 months warranty and it would certainly cost you more than $30 to send back to the US if you had to make a warranty claim.

I don't see why you can't run it in in place of the old o2 sensor but you want to run narrowband which scraps that idea. I don't want to hear anything about it being too close to the turbo. People have tried and done it for a long time with no issues. My car is a road car so I rarely see consistent high rpm and heat.

You may want to consider an Innovate unit. They are still pretty good sensors, quick and accurate, and they have more outputs, ie you can use the wideband Innovate unit to send a narrowband signal so its basically two sensors in one. I don't think the AEM can do that. I have a Power FC with the O2 sensor disabled so I will be removing the narrowband and fitting mine in place.

Threads are the same across most sensors. I don't see the point of removing it. Its a good tool to always have to ensure your ratios are in close to where they should be. Whats to say your narrowband isn't failing and giving your car shit feedback and hindering your fuel eco. If the wideband sensor can fail near the turbo, there is no reason the narrowband wont.

If you are fitting it in a new location, the only thing I know is it needs to be fitted wit the sensor facing down at an angle so any moisture drips off the sensor and not into it.

The aem is good, i recently put one in just after the dump pipe and it works well. It was reading pretty much the same as the dyno's sensor which was recently replaced.

If your fuel mixtures aren't too rich and you don't burn a lot of oil then you could expect about the same life that you'd get out of a standard narrow band which is 100,000k's under normal driving conditions. Seeing as you probably won't be driving under normal conditions then you might half it to be safe maybe.

I plan to replace mine at about 50,000, to get a new replacement sensor is something like $60-70.

All this can be answered by google but here's some help anyway.

1. That is the going rate for wideband kits.

2. Bosch say they will last for 100,000k's.

3. You will get better fuel economy if you don't use a narrowband signal. You can just use the stock location for your wideband sensor. http://www.bosch.com.au/content/language1/downloads/sensors_oxygenlsm11.pdf

4. Did you see mine yesterday? I'll post a pic for you when its light.

5. Yes.

6. I told you yesterday that the wideband setup in my car can output 2 configurable channels. One goes to the gauge and the other one can output a narrowband signal or a wideband signal. The threads are the same.

Q 2 and 6: These questions imply you need to read up on the difference between wideband and narrow band and how your gauge works.

There is a thread that will answer all of these questions just a few pages back.

Thanks Nathan. I didn't get a chance to look at your setup unfortunately. The nice turbo setup must have blinded me

It seems like the innovative may be best if wanting to use it for narrowband signal emulation aswell. It would be a benfit in having just the one sensor and being able to output Narrowband and wideband signal. I'm not sure the AEM can do this properly.

Can anybody with an AEM shed some light on how they have gone using the one sensor for both narrowband and wideband output?

Apparently on the AEM there is a function P04 that can simulate a narrowband. But by switching the gauge/output to that does it mean that the gauge will also show differently or if you running an output to the FC datalogit that the output will then be the 0-1v rather than the standard 0-5v. (i.e. does it not have the 2 channel the innovative does?)

The P04 output seems to show a output of around the 0.5v at 14.7 with the voltage fluctuating up or down from there depending on the movment from stoich. From what others seem to say it isn't a true narrowband signal but sounds like it should work..

The Innovtive seems like you may be able to set the switch point?

Hi Ben. Just a quick tip. It is the wideband controller that outputs the signal. It is not the O2 sensor.
