I'm going to install a AFR gauge in my 944 SP2 car. Looking at the Lindsey page, which 02 sensor do I need? Or, does it depend on the gauge I'm going to order. Thanks for any help.

Don, Innovative Technologies is the one that I use and am VERY happy with it, Like $200 comes with the Wideband o2 Sensor and Gauge, Instructions ECT. Also, The have a "Calibrate" procedure for accuracy.. Im Running the standalone so I need that.. I did notice the only time you get a Good Read if flat out on a straightaway, (to where its steady)... Id get them as a matched set..
It comes with a weld in bung if you're not going to use the factory one, Text me Ill be more that happy to Tig Weld it in for you...

How did the Camber plates work out? Ill be at the Glen Oct 2nd and 3rd, with fresh paint on the car...

i had an AEM wideband for a while, it did its job once i got the wiring right lol

Hi Glen.. Thank you for the notes. Lou has a gauge he pulled out of the 911 when he went to a full AIM system. I'll have that on Sat and figure out what's next. I think I can pull the 02 sensor and install the bung, correct?

Camber plates are in, and alignment is fantastic. Thanks for all that. I will also be at the Glen on Oct 2-3 if all goes as planned.

Since you are running the Stock Engine Management system, I would think that you would have to Either wire the Wideband So that it gives feedback to the ECU AND The Gauge (Which is possible with the one I have) OR to make it E-Z Just run another bung for the wide-band. If memory servers, I recall the instructions telling that it had to "X" Distance from the outlet of my Turbo and and that I could not run it in the factory location. I think it gives it a better read? Anyhow, Im not sure about the NA cars. It also instructed me to "Clock" it about the 10 o'clock position in the pipe to avoid condensation Ect.. Maybe Give BEHE a quick call and ask. I made several calls before I got and installed mine.. Im actually going to lower my FP because it was running a little fat... Brion is coming over next week to help set the car up with me, I just have to finish the paint work this week, Doing some Airbrushing on it this weekend.. see you at the Track!

I run an AEM UEGO in my car, it was about $150 when I bought it in 2015. The controller is actually within the gauge pod itself, which is the common 52mm size. It includes an LSU 4.9 sensor which is standard fare. I installed it directly where the stock O2 sensor went, it's fine. If you have a turbo car the stock location isn't going to work for a wideband.

The UEGO also doesn't need free-air calibration, and there are multiple outputs. One can send an emulated 0-1v "narrowband" signal to a stock ECU, which is expecting that range. The other outputs are the 0-5v wideband signal (for an ECU that can use it) and I believe a serial signal for datalogging equipment that can use that. I just have the wideband signal hooked up to my standalone.

It's not super fancy but it works well and has good response time, it fits my needs fine for a self-tuned NA car. My only complaint is that it's sensitive to ground offsets. I.e. the gauge will be saying one thing, and when I open my tuning software, the wideband signal is showing up as a number that's very close but not exact. Sometimes off by 1/2 an AFR point. I've tried grounding the WB controller to the same ground as my ECU and it doesn't really help. YMMV. Only an issue if you use it for closed-loop fuel control or VE auto-tuning.

Adding another brand into the mix..
I'm running a Prosport Analog AFR gauge in my mostly stock 87 ROW car. Happy with it so far.

Comes as a complete kit including O2 Sensor and bung. Theres a digital option too which is probably alot more accurate? Albeit a bit more expensive.

Thank you for all the replies. I was given a set of AEM gauges. 30-5130. I asked AEM which sensor to order and they told me 35-2001 which is equivalent to Bosch 17018. However, I've read that AEM does something special with their sensor and that I should buy from them. Anyone have some experience with this? I can buy the Bosch sensor from Pep Boys today and save 30.00.

Thanks,

Don

Probably a reference to the calibration. Most popular widebands (e.g. Innovate LC series) require you to do a free-air calibration before use. The AEM setups don't require this. I believe the onboard electronics are somehow "ballasted" at the factory to correct any production tolerances. Sort of like putting wheel weights on a rim.
