Wideband o2 sensor

[koukimonster139]

Searched, but mainly found for sale threads :-/

anyway heres what i got

1997 240sx
s14 blacktop
basic bolt ons
safc
ebc




and here is my question.

I have been running a straight through exhaust consisting of aftermarket turbo mani, elbow, downpipe, 3 inch straight pipe to an apexi N1. As for oxygen sensors, I used the stock one in the elbow, and an o2 simulator in place of the second one. (no cat). I am wanting a wideband so I can actually tell what my oxygen content is instead of my gauge just doing retarded stuff. Is it possible to use the wideband system with my current setup? Or do I need a cat?

also does anybody have any recommendations on a wideband kit or high flow cat if that is the case?

don't believe you actually need a cat for wideband?? since the stock o2 is before cat anyways...

because most people seem to like to put the wideband on the dp, you need to weld a bung on the dp, shouldn't be much..., the stock o2 is too close to the turbo

(i don't have a wideband, only responding from what i've been reading...)

Depending on the turbo dictates the distance on where to place the O2 sensor for the wideband. Hit me up on AIM : RPSport John.

I have a couple wideband options for you to choose from, and can help you with the install too.

go with the AEM Eugo gauge..its awesome ive had one in my old supercharged accord, my 99 GSX and now in my 240 with a blacktop..top quality stuff

AEM FTL, worse wideband EVAR

You ain't fuckin lying here! Never ever run race gas with them either!



In my personal experience, I've fell in love with PLX M300's (or any of ther gauges) I've installed between 10-15 of these things, on everything from stock turbo cars, to v8 turbo cars, and love them.

The best part is, if you were to screw up a sensor somehow, you goto your local parts store, ask for a 1.8t beetle 02 sensor, and your'e set to go again (usually between 35-50 dollars)


No recalibration needed either! Plug in, and go. I'm using mine to supply the narrowband output to my ECU as well. I noticed the car ran ever so slightly smoother running it that way vs the dual sensor.

I'm looking into getting a wideband as well, but I'm not sure what to go with. I am currenly running a stock redtop except forsafc2, mani, outlet, dp, test pipe, and exhaust 3" straight through. Is the test pipe a viable location for the sensor or will I need to weld a bung to the dp? Also, I plan on upgrading a quite a bit is there any limitations to any of the widebands?

I have had the NGK AFX for a while now and it is awesome. I have run race gas and premium pump gas with no problem and the price is reasonable too. The display is easy to mount and easy to read also.

Ok, there is something you should know about wideband stuff.

It is divided into two parts.
1. The Controller
2. The Sensor.

The most commonly used sensor is the Bosch 5 wire sensor, like the beetle uses. It is inexpensive and takes to leaded fuel well. It is not very good with extreme heat (think rotary). So mounting this sensor further down stream is going to be a good bet (like, 4 inches before the cat.

The controller. Everyone argues that their controller is better than others, but they are all pretty much exactly the same. Minus the aem, that is a POS.

Do I need a guage with my wideband? No. You need DATALOGGING.

The ability to graph the AF/R vs RPM vs LOAD is what is going to help you to accurately tune your car. The LM-1 is handy for this because it datalog's in the box itself. Dont be fooled by flashy displays or guages. You will not have much luck tunning with these, unless you are on the dyno, under a constant load, which 99% of the time, you will not be.

Funny story about NGK. I was at sema. Went up to the NGK booth, there they had the AFX laid out, pushing it. I asked them, why is this wideband controller better than any of the other competitors.

"well it has a easy to read guage on the controller"
"so what, you have to datalog to tune anyways, what else"
"well, since we make scientific oxygen sensors, we know what we are doing."
"Isnt the AFX getting boxed with the bosch sensor though"
".... well, yeah... but the NGK sensor is scientific, and alot more expensive."
"So why is this controller any better...?

Personally i like the PLX devices wideband controller, it has the fastest data sample (Frames per Second) rate out there. This comes in very handy street tunning and data logging fast cars.

I also sell the innovative/haltech LC-1 Wideband, and replacement gear, and a baller http://static.zoovy.com/img/rpsport/W180-H146-Bffffff/W/wideband_display.jpg af/r guage too. This stuff works, works good, but i like the PLX better. When I become a PLX dealer, i will be selling their stuff too..

Hope this helps, go with the PLX or Innovative, the NGK AFX is spending $100 more for something doing the same exact job.
