I didn't know whether this belonged in the Engine forum or here, but here goes.

I have come to the conclusion that my A/F ratio gauge is useless, I need a Wideband o2 sensor.

There are 2 that I have looking at lately, the FJO and the Lambda units. The thing is, I've been trying to see if I can get more information and if I can somehow work out a group buy for these if anyone else was interested.

Can someone help me out? Or better yet, if you have one (Onpol and Red I think) what do you think of them?

some links you might want to consider.(and for everyone else)

bah...there is no way in heck that I'm doing it do it yourself.

I'm just plain lazy smile.gif tongue.gif

I gave FJO a notice about wanting to a group buy. Would anyone be interested in joining this if FJO gave us the green light?

At $547-$625, wideband o2 sensors are definetely not cheap. However, when your serious about tuning your car, this piece of equipment is certainly a must.

It will be wonderfull to have a WIde band O2 but the cost is too high and the life of this sensors is short.The best use of this equip. is just to tune the car and thats it not to leave it in your car for everyday use.Thats why is wiser ($) just to use the one in your dyno shop.

Quick question guys and it might be a stupid one. Is there an O2 sensor out there, be it from a honda, mitsu, ford, etc., etc. That would be compatible to use with our ecu and give us a better more accurate reading.

MaierApril

not that I know of

turbulence

no. a wideband o2 sensor has a different output voltage range than stock o2 sensors. and even if there were an o2 sensor that would give a more accurate reading, the ecu wouldn't know the difference. .5v form either sensor is the same to the ecu.

EL Tiburon

so basically what you are saying is that the O2 is not the problem. It's the way the ecu reads it.

No, the problem is both. The stock o2 sensor only reads a very narrow range of mixtures, and uses a very limited voltage range to report it. The stock ECU can only "understand" that kind of o2 sensor.

If you were to get a wideband O2 sensor, you would need a custom gauge/display to 'read' it, and you would have to make the tuning adjustments necessary.

Only aftermarket "stand alone" ECU's can read/understand/make adjustments off a wide band o2 sensor.

Actually, there is a Honda Civic (HF?) I believe that used a wideband sensor in it's STOCK exhaust. Do a little ore digging around on the internet, then the junkyards, and you'll have the sensor for next to nothing.
