yes ihave been searching and came up empty handed!!!!

ok theres this really smart guy (he was going to be a doctor if this helps) at my work (bmw dearlership) any way he was telling me about this turbo setup hes going to be puting on his neon. so i asked what kind of tunning you going to use and he says hes going to do it. som im interested in himm buying a wide band so i can tune my ca with it too. wrong hes going to spend $50 on a wideband sensor and is going to use a vot meter to decide the a/f reading. im confused and i want to do this similar setup if it works but my thought was that it would only read narrow band? plus if this does work any one no a good software program that can handle the input from the sensor plus decide the a/f ratio and some way of recording this i thought this would be way beter than buying a $380 wide band.

any info is much appericeated
yea i cant spell

thanks

Well, your o2 sensor should have five wires, Heater, heater ground, power, signal, ground. The o2 sensor works by changing voltage according to oxyegen content, All you have to do is measure the voltage between signal, and ground. Simple as wiring the signal to voltometer plus, then to ground (-) battery terminal is best. I'm not sure at what voltage is stoich, rich, or lean, but If you do some research about your specific o2 sensor you should be able to find it.

Of course it has to be a WIDE band o2 sensor, not the normal $50 super narrow o2 sensor they'll do absolutely no good on a turbo'd car. To tune it, get something to adjust a/f ratio such as a S-AFC, V-AFC, Hondata, Uberdata, or something of the sorts. This is really a whole nother topic in my opionion.

 

any one no voltage

 

Wideband O2's are available for $50 - the sensor anyway (from a VW, the Bosch LSU-4).

You still need a controller box to make the wideband work. Wideband O2's don't work like a normal narrowband O2. You could put the narrowband O2 in a bench vise and use a torch to get it to generate a voltage. The same would never happen to a wideband.

So tell your friend that he needs to buy a wideband 'setup' and not just the sensor.

You cant do that with a WB02 sensor
You need a controler, bottem line.

 

Oops sorry about that. never mind my previous post.

 

are you sure you need a controller bc he was saying that there will be no need for any other wiring execpt to the volt meter bc its a stand alone or some thing to that affect it doesnt need power wires bc it reads by the voltage so **** ill ask him again tommorw for sure ok

You NEED a controler to control the heater and the sensor. I built a DIY wideband controler for the older L1H1 WB sensor (honda lean burn civic). The controler produces a 0-5v output which you could read with a multi meter and convert the voltage to AFR. Hopefully this guy is planing to do it this way. If not dont let him touch your car

 

got any info on how to make your own controller??

 

DIY WB

 

That ^might give you a rough idea

the controler was easy to build. The damn display is the hard part! I just use a PLX m300 now

 

volt meter for wideband!!! that woould be really cool.

 

thanks for the info guys

 

hey....anyone familiar with the BMW type bosch wideband sensors(LSH25)? These will produce a voltage even sitting at atmospheric mixture...They are a capillary tranport style sensor...hence I wonder wny a controller is needed?

 

never mind....answered my own question...planars need referenced voltage for active transportation of ions across the measurement membrane, thus keeping a lamda of 1...and also, this sensor is an lsu, not lsh25...DIY wideband....functional with any other types of sensor?
