Oxygen Sensor in the Exhaust
Got tired of shooting in the dark so i got an o2 sensor and put it in my exhaust with an air fuel gauge.

i was thinking of doing this on my gs450L that the PO put pods and jets in. lemme know how it works out

OK, I got a heated four wire o2 sensor rather than a un heated sensor becuase I was unsure if the sensor would get to operating tempurature (~600 degrees F) without it being heated. The sensor cost me $50 from autozone and was the cheapest one I could find without ordering one from the internet. The gauge cost me an additional $40 and I got it from autozone as well.
I have one question for anyone who knows anything about o2 sensors. First off, the sensor I purchased was a narrowband sensor and so was the gauge. The gauge reads the output voltage from 0-1volt that the sensor puts out. In the manual for the sensor it says that 0-.4 volts is lean and .6-1 volt is rich. My question is with the narrowband sensor will the i just read rich if it's a hint rich and lean if it's a hint lean because the output is not a linear curve. even though there are about 10 LED's that light up in a circular pattern? I'll get some more pictures and a video up soon it's pretty slick looking so far!

those gages r fine for non racing applications as long as your in the middle your ok. the middle area will be kinda wide, i bet you could go 1 or 2.5 jet sizes up or down and still be good.

let me know how well it does Nick...
What carbs are you going to tune ?
Also after your done, double check your volts with a good multimeter.
I have found some of the A/F gauges are off .2 to .6 volts.
Nick don't use the multimeter while riding LOL
Good luck....
Later

I'm using the 34mm gsxr carbs. I just got back from a spin after I made some changes in the jetting. With the stock pilots 32.5 and three turns out with the air mixture screws at idle the gauge sits at the blue led and oscolates quickly up to the orange led and back down maybe 3 times every 5 seconds. You can hear the engine sound a different tune when this happens if you listen carefully. Once i'm cruising though it goes to the max rich led and if i let go of the throttle and engine brake it goes to the max lean led. I think that's how narrowband works though. I'll post some videos to help explain myself soon..

i think your running rich. the going up and down is normal for the gages (mine dose it on my truck). it should run in the normal range wile cruising, idling and normal to rich at full throttle. the lean during engine braking is normal

As you noted previously, narrow band senors are very finicky. The zone between lean adnd rich is almost a vertical slope. Your life will be much easier if you use a wideband.

ya but at $200+ i don't think it worth it unless you r racing
altho if you use it for more then one vehicle then it would be a great tool

I guess it depends on how much time you think it will save. Another $150 above what the narrow band costs minus the time spent fiddling with it seems pretty cheap in the end. If I ever get around to it, I am planning on doing the same thing. I'll let you know if it was worth it. You're right though. As a method of tuning for more than one bike, it is definitely best.

Unfortunately I left all my carb tuning equipment at my grandmas and have my carbs off and don't want to re-install to get videos without switching to some appropriate jets. It will be a week before i get it re-assembled... sorry..

Also, with wideband don't you need a controller? I can get a wideband o2 sensor for $60 but don't you need something to intemperate the signal or do you just hook it directly to a wideband gauge from the sensor?..

I did this last year. :-) It works great. http://video.google.com/videoplay?do...77991342&hl=enYou'd have to be crazy to be sane in this world -Nero
If you love it, let it go. If it comes back....... You probably highsided.
1980 GS550E (I swear it's a 550...)
1982 GS650E (really, it's a 650)
1983 GS550ES (42mpg again)
1996 Yamaha WR250 (No, it's not a 4 stroke.)

My brother and I rigging it up! The blue is not as bad as distracting as it looks in the video but it's... noticeable.. The rich light is illuminated but it does that as default i guess i'm just trying to demonstrate how the gauge looks.
