I know nothing about the Wideband O2. The only thing I know is that it's a way to tune your cars A/F ratio.

Can anyone give me helpful info or links to get me started in the right direction?

 

It's a way to monitor your car's air fuel ratio, not change it. To change it you need other things, such as a programmable computer like Emanage or SAFC or a JWT ECU (where JWT adjusts the programming for you), or simple fuel pressure adjustment, etc.

 

Do most people make their owm? is there a place to buy a wideband kit? I have an SAFC-2 and once I get enough knowledge I'd like to get a Wideband so I can tune my car on any given day. How much should I know before I start messing with any of that.

 

most people buy a premade unit 300-400$

search google or ebay for wideband kits

if you dont know what a wideband is it sounds like you need to do alot more research before you start tuning your car

 

Well I know it's an O2 sensor that sends a signal to a electronic unit that shows what your air/fuel ratio is. Which allows you to see if your car is running rich or lean. Also I am just learning about widebands. So that's why I'm trying to find helpful info and sites ao that I can learn as much as possible so that when I am ready I will buy one and tune my car appropriately.

 

I"m in the same boat,I know what a wide band O2 do,but never use one,just want to heard some thought of what's available and does not cost a fortune,maybe around $500 with a display unit and egt will be nice.Is the Zeitronic the only one to go with that price range.

 

You can get an Innovate LM-1 with display for less than $400.

Why would you need egt if you have a wideband?

 

all you do is go to google and search "wideband oxygen" and you get all this and many many more

AEM Uego Ownz joo!

 

I'm kind of leaning towards the PLX wideband setup.

Does anyone know if NTK sensor outperforms the bosch sensor enough to merit buying an NTK system over a bosch?

 

I was lookin at that one, but the gauge only goes down to 11:1. Does the digital readout go lower than that?

 

Also look at the zietronics

 

No.

Think about this though... why would you want to monitor the AFR being that rich? If the reading goes off the scale rich like that, isn't the important thing now to get that AFR back up? I don't see any benefit in having the ability to tell you what the AFR is at that level, especially since you can't run a car like that.

Same for the other way around... I don't think it's important to be able to see what the reading is, for the AFR, when it exceeds the 16.75 maximum that the Uego is set for.

Your biggest concern in both of these situations is to get the AFR back into the measurable scale - not worrying about what it is when it's off the scale.

Of course this is just my .02 cents.

Do you know if any other WBO2 sensor reads lower than 11.1 or higher than 16.75? I would think that the majority of WB02 sensors work in the 0-5 volt range - therefore all WB02 monitors would be restricted to the same ~11.1 - ~16.75 scale...

 

Basically all wideband work the same just different company and feature right?Is there something you have to get xtra for the Innovate LM-1 with display(for less than $400)?What's the main different between Innovate LM-1 with display and the Zeitronic with display(I'm leaning on this one cause it has the egt feature)?Well the reason I want the egt was that,I hear someone told me that the egt will tell you what's going on faster than the A/F does,is that correct?Sorry for asking too much question,I'm still learning this wideband stuff.Thanx alots.

 

Sorry I already got the emanage with the ign and injection hardness,don't know if any of this will work better with emanage or not.

 

The EGT gauge will give you a clue about whether or not you're running too lean or too rich - rich = cooler temps and lean = hotter temps, but the WBO2 is going to give you an exact (within 0.1 or so, AEM claims) measurement of your mixture.

I'm sure that there are other reasons why your EGT could climb that aren't a direct cause of your mixture being to lean - like driving under a load (uphill, towing) or something. The WBO2 on the other hand will tell you whether or not your mixture is truly too rich or too lean.

Why do you think dyno shops use WBO2 sensors and not EGT sensors?

But hey, I've got them both, so I'm covering all my bases...

I have the e-Manage also. You'll definitely want to get the WBO2 sensor if you plan on trying to tune the e-Manage yourself.

 

that makes no sense i would think if you went lean your A/F would sky rocket faster then your EGT

the NTK sensor isnt worth the extra expence

 

Thanx for clearing this up for me,so I just need to get the wideband then,which one do you have?Anyone have experience with something that's simply to use and read with a display(like the Zeitronic or Innovate LM-1)?Thanx for the help guy.

 

Dude... look at the AEM Uego from the link posted above...

Can't much simpler than that. It also fits in a 2 1/6" gauge pod!

 

IMO, the biggest thing to look for is datalogging capabilites and tach harness. If you can't datalog rpm and afr, they lose a lot of their utility.

 

This was written by Klaus, the inventor of the Innovate LM-1:

Ref: http://www.innovatemotorsports.com/f...&highlight=ntk

Differences between Bosch LSU4/4.2 and NTK:

1. Response speed
Measured by the sensors own response delay between pump cell and sense cell:

Bosch <5 msec
NTK ~50msec

2. Back Pressure sensitivity

Bosch sensor has about 1/3 the NTK's pressure sensitivity.
Pressure sensitivity means that the sensor reads richer than reality in a rich mixture, leaner in lean mixture.

3. Temperature sensitivity

NTK sensor is fairly insensitive to temperature either at bung or EGT, can run with constant heater voltage.

Bosch sensors are very sensitive and needs to have precisely controlled cell temperatures. Bosch sensors are sensitive to housing temperature.

4. Heatup time

NTK ~60 seconds
Bosch ~20 seconds

Diferences between Bosch LSU4 (066) and LSU4.2 (057/058)

1. Heater response time
066 sensor has higher thermal mass and responds slower to heat input. This makes the 057/058 sensor a little bit more challenging to control, heater PID must react faster.
No problem in the LM-1, because it's already designed for the faster response of the 057.

2. Sensor tolerances
066 sensors have tighter tolerances between sensors. This is not an issue with the LM-1 because it is calibrates to the individual sensor when doing a free air calibration.

3. Connector is different.

4. 066 sensor is slightly more tolerant to overheating of the sensor housing at the bung. It takes longer to give completely erronious values, but has the same specs.

5. 066 sensor is more expensive.

 

So not all wideband O2 had tach harness?

 

no, some don't even datalog. i.e. the cheaper PLX devices units.
The Innovate LM-1 is great but the tach harness is ~$100.


Just research and you will find a unit with everything you need.

+1 for the AEM Uego.

i use the EGT to montior temps over a period off time lets say during a top speed run if i see it go up to high i let off easy.

i would get detonation @ 1100 F before with an afr of 13~:1 (on the uego)

i was able with the AEM Uego to get my car to peg 1380F EGT on a top speed pull.
which is where my EGT were at before all my detonting problem occured.
when i was running on the detonating motor i would see EGTS between 1400~1500 with very bad detontaion which ended up after a year and a half costing me a motor.

im still waiting on some time to make a trip over to the dyno for some pulls.

 

I just bought Innovative's XD-1 standalone gauge, it's supposed to be here Wednesday. I'll post and let you guys know how it is.

 

I talk to sx7r,he told me that I can use the AEM hook up to my emange to datalog(or moniter) on my computer,is that right I can used the rpm on the emange and the a/f on the AEM together,or maybe I misunderstand him.Kinda like the way the AEM look too.

 

the aem unit does have a signal output wire IIRC
so you can hook it up to ems

 

I have an M-300 PLX wideband is goes lower than 11:1. My digital readout goes from 10:1 to 20:1. Anything outside that range will read as "rich", "lean", or "air". I've been running my wideband Bosch PLX setup for over a year now and I have great reviews!

:edit: Here is a video of my wideband o2 sensor while I was revving the motor. I made the video because of my cutout, but it shows a good view of the digital readout.

Today I just finished wiring up my Innovate XD-1 gauge. I have to say it works really nice, but it's a little confusing. I still have to figure out how to datalog with it, but the led "needle" is programmable with different colors and corresponding values. I'm pretty sure the range on it is 9.0-20.0 AFR. The controller also has two analog outputs, so it can be hooked up to a separate logger/ECU tuning device. The wiring was pretty complicated, the instructions don't do a very good job. The wires were a little short too, I had to add some. Other than that, I'm happy with it!

Anyways, just thought I'd share.

 

I have the LM1 From Innovative. I purchased that because I wanted to take it from car to car because I have alot of people that will need their cars tuned this summer.

After seeing Brad's (see above post) Gauge in the car from innovative for a perminate tuneing tool that'll stay in the car I'd choose that for sure. It's got great readout and display. Colors help at a glance and it's just the right size.
Brad... I think once you get the spring needed to change your boost up in the 10range you'll be able to MPH better. It's well on the way to running great! Keep up the good work!

I am going to supercharge my max very soon and I am looking into how I will tune my car. I decided to go with an eManage wired to my carpc that is permanently in the car. For a wideband o2, I just can decided what to go with. My top choice as of right now seems to be the Innovate LM-1 kit with the RPM converter. I like the idea that I can use any A/F gauge with this kit. Dynojet Wide Band Commander seems to be a good deal and it comes with a gauge. I heard good things about the AEM Uego and the PLX kits but there was nothing that really apealed. Any suggestions about which to go with would be great. Thanks.

 

Ahh, why do widebands have to be so expensive

 

Go with the Innovate wideband. Its a great kit, you wont be disappointed.

 

I bought the Dynojet and I like it quite a bit. It was easy to install, and it has powerful features. It has outputs for the included guage and warning light, as well as USB for your laptop; an output you can hook up to emanage with autotune to automatically correct a/f ratio, and a programable solenoid output.

It can datalog multiple inputs, such as a/f ratio, RPM, throttle position and boost at the same time. It can store the log internally, to output to laptop later, or it can output in real time to laptop.

You can have the programmable output logic do something like "if throttle position = wide open, and boost > 6 PSI then activate water injection".

 

which wideband would you recommend to run with a emanage with profec e-01?

There is an opening I can use right on the turbo practically, I wonder which can handle that heat as a perm install? You can build/get a heatsink for the innovate setup I think.

 

i'm running the zeitronix and its quite a bargain since you can monitor a/f, lambda, tps, boost, and egts with just one unit. Add that along with the datalogging and monitoring capabilities.

however, sometimes the lcd screen is hard to read so i'm thinking of making a little screen for it. IIRC its was $345 for the whole unit plus lcd screen

 

I'm running the Zeitronics full set up and it is pimp! With the basic package ($399) you can log data on TPS, RPM, and AFR on your lap top, or display it on the supplied display. For another $109 you can get a boost sensor, and for $65 you can get a EGT probe so that you can log AFR, RPM, boost, EGT, at certain TPS signals. It gives you a lot of info, and for a minimal expense you can move it from car to car. I bought a 2nd main harness and an o2 sensor harness, that I have used on 3 other cars, but the EGT stuff has not been used.

 

You install it on the manifold or the y-pipe.

 

Thanks for all the replies. Now I think Im going to go with the Zeitronix, do any of the other kits have the ability to record a/f, lambda, tps, boost, and egts?
