Well recently I thought my stock O2 sensor was failing. I COULD have simply replaced it, but I had also just built and thrown in an H23 VTEC into my Prelude and had bought a VAFC to tune it out, so I thought, "wouldn't it be nice to be able to tune it myself?" So I started looking for a cheap wideband.

While looking at this thread and was about to order an Innovative Motorsports wideband when I read about the one person that mentioned the Zeitronix wideband. I started looking into this option, and was very interested in the package that it had: cheap wideband w/ datalogging that hooks up to your laptop, w/ no need for a display otherwise, the cheap Bosch O2 sensor, and all necessary equipment for under $300. From what i was able to read, the ONLY thing that it lacked in regards to the Innovative Motorsports wideband is the auto-calibration feature, which I thought would be very important, but I couldn't justify the extra money for only that feature.

So I bought the wideband through their website, and bought the optional serial-to-USB cable for my laptop, since it didn't have a serial port. I also opted for the 2-3 day shipping. On the 4th business day, the wideband got to my door. I opened it up, and everything was packaged very well. It came with all necessary instructions and wires, and everything looked good.

The sensor has a nice, very long lead on it and was easy to run through my car.

The laptop data cable is also long, and allows for a lot of movement when hooked up.

The actual wiring harness looks a lot like a VAFC wiring harness, and is similar in installtation; you just splice the wires, plug in the harness, and you're ready to go! The only thing is that I would have liked for the harness to have been longer, but it's nothin a little extra soldering can't fix.

The actual brain box is roughly the size of a box of cigarettes; it is very small and easy to hide. The circuitry is enclosed in a sturdy plastic box that looks like it will take a beating without a hiccup.

The installation was fairly straightforward. I simply spliced the wideband's harness into my VAFC harness to reduce the number of splices on the actual ECU harness. Once everything was hooked up, I plugged in my laptop, cranked the car, and started the program, and started logging.

The program is great and easy to use, as well as easy to install. It logs everything you could need, including the optional EGT, boost sensor, etc....sensors that you can buy separately. It gives a nice, easy to read line-graph display, and it's easy to move the pointer to a certain RPM to see what all the other sensor's were reading.

I also liked the narrowband output feature; it allows you to run your ECU and normal Autometer/Faze/etc 0-1V a/f gauges off the wideband's signal. I was able to simply unhook the stock O2 sensor, install and run the new wideband O2 sensor, and tap into the ECU's O2 sensor wire w/ the narrowband for its signal, allowing you to run the wideband in place of your stock sensor with no welding required. The only thing I haven't been able to do yet is stick a resistor inline w/ the stock sensor's heater circuit to get rid of code #41.

Overall, I would say this is the best wideband you can get without breaking the piggybank. I have not had a chance to personally use or install any others in my car, but from seeing others, this seems like it's up there w/ the best of them. I will be getting some pics later of the box and installation, and maybe some shots of tuning-in-progress, if I can get out of work at a decent hour.

I'm happy to answer any questions anyone may have

 

Can you give us any info on the warm-up routine, or calibration.

On the PLX, there is no indicator when it is warmed up or not, and it will read ~14.7 until it warms up, but it is a false reading.

Also, in my VERY LIMITED experience with the PLX, it didn't have any buttons/*****, so there was no way to tell it to re-calibrate to free air.

-PHiZ

 

I don't know if this thing can be recalibrated, and it came w/ no instructions on how to do it. I will prob. email him about it today to see if it can be done.

Also, warm up takes about 30 seconds. I believe it reads full lean until it warms up, but it could be full rich..........I've only had it on a few days and don't remember.

 

I still like my LM-1. Good review though

I would have to say all of the affordable WB out there now are very good. PLX, LM-1, Zeitronix, TechEdge...they all offer great products at great prices. None suck and none stand out!

 

Thank you very much for your review.. i think im going to order the zeitronix for myself. You dont live far away from me, we should have a test and tune day! lol

Haha, sounds good!

One day we should all meet up, though. I've been wanting to get a huge gettogether, but I just don't have the friggin time right now........... :runs and pouts:

 

Yeah, ive missed every local h-t meet.. id really like to meet some other ATL area h-t members

 

i like my zietronix as well. i logged the entire day on it and now i gotta go back over my logs lol

 

So has anyone logged their stock map sensor read outs with it?

 

anyone have a picture of the display unit in the car? Just wondering were people are mounting it

 

i owned a laptop and decided to use it instead of the display

im using my afc to moniter map voltage since it converts to mm/hg for me

 

i thought of that too, but thought it would be nice to have it log the rpms/map/afr all together for ease of tuning

 

I'm ordering mine really soon. I'm glad I'm hearing a lot of good opinions on it.

 

I ordered mine a few hours ago. I will try to do a full write-up

 

looks like alotof GA guys in here.

i had a little issue with runnig open header while street tuning (dont do it)

but now that ive got an exhaust on it, the #'s look real good.


im gonna spend all day tomorrow settingup my maps, but yea its great right now.

 

sorry for the BIG azz pics. I bought mine about a month ago. havent installed it yet Im waiting on my turbo to do it all at once. I will also give a review of this product after completion of https://honda-tech.com/zerothread?id=974988

 

Has anyone been able to log their stock map sensor with it?

it can be done there is one user input, as well as a boost input, which im sure could log the map too.

so it is possible, but i am not using it.

 

All i can say is, Great Wideband!

 

i have an autometer EGT gauge could i use that sensor with this widedand?

also let us know if anyone can get their stock map to datalog with this unit.

also the display looks really nice aswell. personaly i would buy the display so u wouldn't need a boost, EGT, or a/f gauge, u could just use the display for the wideband.

U can disable the o2 heater in uberdata, so that would solve the engine code problem.

 

hey FYI this iss what your tuning with..

as you cn see there is a spare input and a boost input to tap for MAP

i just made this log earlier while tuning my car out

Yep, it comes with an EGT 2-pin connector and lead wires to hook it up.

 

so really if u bought this unit, and bought the boost sensor, and EGT and the display. it would run u close to 500.

but take 125 off for the autometer EGT gauge that u would have built in
50 off for a good boost gauge
50 off for the narrow band o2 gauge
and if u placed this right u wouldn't need a large tachometer either 100

so thats 325 off. so u would be paying 175 for a wideband o2 sensor.

i think when i get an extra 200 bucks im ganna sell my boost gauge, EGT gauge and sensor and buy this unit. less gauges to mount, and acurate a/f readings!!!

 

Someone needs to start a group buy.

i know a mercedes forum had set one up a while ago.....we should start one for HT
