I would like to install a wideband sensor. I don't want to drill a hole into my DCsports header so I want to use the stock O2 sensor location. I read through a couple of threads in other forums and found the answer I want to hear. Most of the wideband sensors have a narrowband simulator that I need when using the stock ECU. So one of my questions is if our ECUs (e.g. my '98 one) are able to read and use the signals that come from the wideband when using the analog output of the controller. Will there be any problems when replacing the narrowband with a wideband? I don't want to drill any holes into my header...
Another question is which wideband sensors are self calibrating? There are AEM UEGOs, Innovate LC-1, MTX-L .... which one is the best and the easiest to use?
(Sorry for my probably bad english, I'm still learning and these technical and automotive words are not common when learning a language, haha)

I believe that the point of the narrowband output is to be just good enough not to throw a check engine code. If you are still using the stock ECU, the narrowband output is unlikely ideal for performance or mileage. I would just drill the secondary hole several inches away from the location of the stock sensor. That's what I do anyway. I've only used the LC-1. I've used a couple versions of it for 8 years now. It is probably the most accurate, but is definitely temperamental. It is very sensitive to proper grounding and voltage spikes. It can also get confused and need to be reset. I have my secondary output configured to drive a gauge, rather than a narrowband output. You can calibrate the sensor to ensure accuracy throughout its life. Some of the simpler controllers don't let you do that.

I agree with above ^^
The LC-1 does not "self" calibrate, you have to put it in calibration mode, but there are no knobs or voltage measurement needed, just let it calibrate in "free air", it takes just a few minutes.
Don't forget to calibrate it before you put it in, sounds like a dumb warning, but I got excited and threaded mine in, which required removing the AC compressor for clearance. Then I realized I had to calibrate, which meant pulling the compressor off again. Hopefully yours will be easier to get to, mine is on a down-pipe in a bad location. They are a bit longer than stock as well.
I made a video here about wb02 with respect to megasquirt, but I explain what the narrow band output 'should' do... as mentioned above, it might not act like a real o2 sensor for fuel control. Just be sure you get the correct cable color (yellow or brown) on the LC-1 if you get that one, one is 0-5v, one is simulated, I forget which off the top of my head. I did use the simulated output on my stock ECU, and it did not throw codes, but I did not leave it long before going to megasquirt.
