Ive read somewere that bosch makes a wideband o2 sensor for vw that is a wideband and it fits into the stock honda harnness. 92-95 And probably more years. I looked it up and the connector is the same. SO I was wondering if anyone has been using and has had good results.

Anyone at all.

 

You can't just plug in a wideband sensor into a Honda engine harness and be able to use it, or get any useable reading from it. (The Civic VX uses a wideband, which is an NTK sensor, though.)

You may want to do a search for PLX devices, NGK AFX, Motec PLM, Innovate, etc..

 

THanks for your reply but your telling me two diffrent things. I cant use it then I can. Please explain.

almost all honda use narrow band sensor, exept civic VX!
Wide band sensor need special circuit

 

What kind of special circuit? Whats the diffrence between the two? Is it possible to wire the vx sensor to a dx or ex harness?

Im basically just trying to eliminate some wires getting in the way an taking up space.

 

the wideband basically needs a controller for it to work properly...

and you only need a wideband if your ecu is tunable (which stock ecu's are not) and you plan on tuning a/f ratios on the street...

other than that its useless, other than maybe hooking it up to an a/f ratio gauge..

ok my ecu is tunable thats the point of me even asking? Wait ok putting all this together I see. The plx device will be my controller for the wideband 02.

So if I went and bought a vx o2 and a plx. I would be able to wire those to my ecu through the say the stock harness.

Thats the link to the plx devices I was refered to earlier in this forum and it has the exact bosch o2 sensor I was talking about. And It is available with the controller.


Think you guys for your help I appreciate it.

Now back to the original question?

Has anyone used it and and had good results or bad results.

let me make this simple. NO you cant wire any type of wideband o2 sensor into any of your factory harness or ecu. a wideband is its own sensor/guage. all it does is tell you the A/F ratio. the VW bosch sensor youre talking about is the sensor most companys use in thier wideband kits. the VX sensor can only be used on a VX, with VX wiring, and a VX ECU.

understand now?

So basically Your telling me its only a referance to me and not my ecu? That really doesnt make sense at all. If my ecu doesnt know what my a/f ratio is then how can the software protect my engine from blowing up? How can I datalog? How would it know when i step on the throttle besides the tps which doesnt read oxygen so therefore wont determine how much fuel to dump accuratly. (i know I can spell for sh+t)

 

Wideband sensor kits are indeed for your own reference. The sensor plugs into the gauge and you read your afr. I know the UEGO kit has another port in the back of the gauge which is used for datalogging and such (i don't use this) if you plan on tuning the car yourself. That is what the widband kit does.

Your ECU is completely separate. You can use the information from the datalogging to burn your own chip. Once you've got the tune you want burned onto your chip, you can place it in the socket on the ecu and drive away. Your wideband does not tell your ecu to do anything.

The wideband sensor and gauge are tools to help you tune your ecu to your desire...based on what you have been saying it sounds like you wanted to get a tune out of just buying a gauge/sensor and datalogging. You use the info from your wideband kit to then tune your ecu

 

the stock ecu only reads 0-1v while wb output is 0-5v. usually.


you need a narrowband signal from the wideband kit, thats the signal you can tap in the o2 sensor signal of your ecu,

Oxygen sensor voltages are also not linear, which is another reason you need a dedicated controller. <U>To make it simple, the Bosch wideband needs a special controller to</U>: calibrate it, heat it up, interpret the voltage output, and to deliver both narrowband SIMULATION and wideband outputs. Simulation means you can run it in place of stock (with the wideband's controller), although your stock ecu will throw a CEL for the heater if you don't put a load on that circuitry.

Widebands are not really benifitial with a bone-stock ecu's. It will just tell you the afr's need to get tuned with an aftermarket EMS...

 

ok Lets see if im understanding .

I need a wideband and a controller to see my a/f ratio more accurately. I can link the wideband to the ecu through its narrowband line but is pointless so I should just disable the o2 sensor and link the wideband and controller to my laptop for datalogging.

does this sound good or no?

Now if Im running crome Or ectune will either of those programs protect my engine if and or when I make a mistake by leaning it out too much?

 

may i ask why you are so interested in getting a wideband and tuning software? if your car is stock or just has an intake, it's pointless to be wasting this kind of money.
For your last question, you're making this sound like Crome and Ectune fix the tune on their own. That's NOT how they work. Crome and Ectune are programs you use on your laptop. YOU, the tuner, decide where the fuel should be increased or decreased. You don't just plug it into your ecu and expect it to magically know how it should be running. You should probably just save your money for real power upgrades and worry about the tuning then.

 

You can use eCtune with the wideband to target a specific AFR, but for higher rpm & boost, it won't react fast enough if your base fuel maps aren't close. I think eCtune may have lean protection, but I can't remember. Tuning is a little harder than some make it out to be.

But I have read that some programs protect the engine from going to lean. Or should I say letting you upload a bin map to the ecu that will let you go too lean.

I did get schooled as far as the o2 sensor issue I had because if you read progress of another noob youll understand. But anyway thanks for you time.

Im sure it is. But ls blocks are a dime a dosen so Ill buikd one while I play with one. Its fun to learn and play with the diffrent options. Fuel and spark is the key. When and how much is the problem. Isnt the point of datalogging to get map as close as possible, and to see whats hiccuping?
