I need to know something...
...Did I screw up by getting this gauge? It's a Defi "D" a/f ratio gauge. Everybody on here is talking about a wideband gauge is the best to get. I can't seem to find out if this is a wideband or not! I don't think it is because my searching on here is showing that they are pretty expensive. I gave $112 for this one (ordered it saturday). I'm getting this for my nitrous setup and I want it to read right. If it is a narrow band, how can I make it read correctly?

People usually get wide band for tuning their cars on turbo or supercharged applications. You could use a wide band to tune nitrous also if you wanted to.
An a/f guage would be important when running any kind of FI because you want to make sure that you're not running lean at any point during acceleration. If you hook up your own a/f guage and it's running fairly rich while spraying, you should be okay.

Looks like you need a wideband regardless.
Get one from Dezod, he has them on sale now (read his sale thread)
As yeat I still dont know why someone needs a narrow band a/f gauge. I think they are useless, unless its Christmas.

Rep Power: 423 Just buy the wideband O2 sensor and hook it to that gauge. The gauge isn't any different... the sensor output is what it needs.

Rep Power: 423 I'm not sure what the output should be. 0-12 or 0-5 sound like something that would be feasible. It should come out in volts, you just need to know what the gauge is set to convert.
Ok, so I'm assuming our cars have the 0-5 volt sensors and the narrow band gauges are 0-1 volt, right? Sorry for all the questions but I just want to fully understand this.

narrow band gauge with w/b o2 is a no-no.

Rep Power: 423 I stand corrected...
"Some newer vehicles are being produced with what is referred to as a "wide band" oxygen sensor. This sensor produces a 0 to 5 volt signal, as opposed to the older sensors that produced a 0 to 1 volt signal. While the new vehicles are designed to use the wide band sensors our air/fuel gauges are not, and will not work with them.
Some examples of vehicles that use the wide band sensor are; PT Cruiser Turbo, Dodge SRT-4, all VW's, Subaru WRX, and most turbo and supercharged new vehicles. If you are not sure what your vehicle uses, check your oxygen sensor. If it has more than 4 wires, it's a wide band sensor. If you would like to use our air/fuel gauge on one of these vehicles, you will need to purchase our model 2244 oxygen sensor. It can then be installed in your exhaust to drive our gauge. The original wide band sensor will still be required to run the stock components on the vehicle."
(pertaining to Autometer)
A std. O2 sensor reads 0-1V BTW. I found that too

Ok, so let me get this right. Our cars have a narrow band o2 sensor right? Well, if the gauge I'm getting is a narrow band type, it should work right? Are you guys using the wide band to get more accurate readings?

Rep Power: 413 you can't just add a wideband sensor and call it a day, you bought something pretty...well... useless. Sorry. It's got pretty lights though!

Rep Power: 811 our cars have a narrowband sensor and hooking up a wideband or narrowband gauge will tell you nothing. you need a wideband gauge and wideband 02 sensor.
