I haven't really heard any feedback from people with these inexpensive widebands. The price tag is very attractive, but I am wondering if they are accurate and reliable enough to tune with. Has anyone tested one against a professional wideband setup?

Also, has anyone used one with a PFC Datalogit?

Uego.......

If you want truely tune your car, they range from $400 to $5000.

I do like the lambdaboy...(sound lame) but this one work well.

 

the diy wb is accurate as tested by many in the mustang crowd. that's where i come from. hehe. just bought my rx7 on tuesday.

 

I've got two of the oz-wb and am quite pleased with them. I would rather have a four gas analyzer to help get my timing more spot on but I don't have $10K to squander on one.

As for comparison it's hard to say, it seems to agree with what Dave at KD logged on his dyno but then I am comparing in different conditions on the road.

Maybe the next time I take the DP out I'll put another bung in it so if I take it to KD again we can do side-by-side comparisons.

I also have the datalogit but have not had much time to play with logging. My car has been in the hands of someone with a four gas analyzer to get the <3000K maps to pass MA emissions - possibly with a MP (no cats).

 

I built one, and the display from Tech Edge.. Peter is a good guy to deal with. It had an issue, but he offered to take a look at it for me. Should be back in a week or so, all tuned & ready to go.

And yes, I intend to integrate it with the datalogit that I already have,

 

I heard there were some issues putting the techedge together. Anyone here succesfully put it together?

 

Having had a former life as a manufacturing engineer for telemetry equipment:

No real problems but I've seen less requirements for post-layout mods. Particularly in regards to physical fitting such as the heat sink.
Of course I realize that Peter does not have the $ for mutliple prototype passes to iron these sort of things out.

The display is not bad but I feel it suffers from jumper abuse. I understand the new display is double sided so this may no longer be a problem.

Maybe I'm just picky having done Milspec designs for the military.

 

Newberd,

Do you know if they (tech edge) are taking orders for pre-assembled units again? Web site has not been updated since May, so I was just wondering. Also, where did you buy your sensor? Is it a five wire sensor? How much did you pay for all of the stuff?

Also, I would really like to hear how your data logging goes with the datalogit. Are you able to program the datalogit to convert the wideband output voltage to AFR? I am very curious how this works with the datalogit.

Many thanks,

Jeff

 

ARex, I don't know. I know that Peter's pretty busy, and I did see that he suspended the pre-built units, still.. I think he's refining a few things, probably to make it easier to build & support.

I got my sensor from the parts bin.. $120 or something like that. Yes, it's the 5 wire L1H1. I'd bet that you could hit a honda junk yard with an O2 wrench and pluck one for five fingers, or a minimal charge, if you wanted to. But less than $200 is allready a bargain for a wideband.

I haven't screwed around with datalogging yet. It will at least log voltages, which can be converted to AFR in excel or something. Ideally what I'd like to see would be some software that would keep statistics on where you are on the VE table, let you set a target AFR for each cell, and self-tune if you will. I don't think this should be too difficult to come up with. But we'll see.

 

Cool, thanks for the info.

If you would be so kind, keep us posted on your datalogging efforts when you get started. I think I will be getting the Datalogit and wideband soon.

Thanks!

Jeff

 

I got my tech edge WB in about 2 weeks ago. I ordered the pre-assembled model. (version 1), the second version wasn't out when I ordered...
I got the 2.6m kit, it has more than enough wire to run the length of the car (not that we need it)
I purchased my o2 sensor from a guy who had an extra for $150 and the WB kit was $240 US.
I have it installed but I havn't hooked it up to the datalogit yet.
The display is rather large, larger than I had expected. but it looks nice, and seems much better than the Autometer AF gauge. I just hope it is accurate...I am not really sure how to test it...

Has anyone wired the Techedge WB to a datalogit yet? I havn't found much info on it.

 

I built one that doesn't seem to work... I'm not 100% sure if my sensor is bad or if my building is bad...

Anyone near Washington DC have a WORKING wideband setup that can use the NTK sensor? If so, you could try my sensor on your circuitry to see if my sensor is bad or what. Newbernd? If yours works when you get it back would you like to meet up sometime and try my sensor?

Brian

 

Brian,
I have the entire kit prebuilt from techedge. I'm waiting on getting a bung welded into my exhaust. Good for you are all my aprts are sitting on my workbench. Drop me line if you want to try any of my parts before I install them in my own car.
And yes i too also intend on hooking it up to the Datalogit software which I have installed in my car.
FWIW Bought my O2 sensor from local NAPA store for $138

Regards,
Crispy

 

I spend this afternoon getting all my wires cleaned up and also hooked the WB into the Datalogit. I am getting voltage reading from the O2 sensor, it doesn't seem to quit mesh with what the display says...At idle the display reads 11.1 and the voltage is around 1.95....which according to the website should give me about 11.8
I guess I need to remove the sensor and get an Air reading...that should be around 4volts.

Has anyone calibrated their sensor? From what I understand, If I subtract 1.5 volts form the open air reading voltage, that will give me the voltage where the lambda value is 1.....right?

 

Chris,

This would be great! I have my wideband I built and the sensor... just don't know which one is bad. I would love to come over and try my sensor on your circuit board or whatever! I'll give you a call and we can work something out

Brian

 

Brian,
Sure thing. You have my number.

Coop,
Sounds like you have a floating ground. Read the datalogit board. there has been much discussion on this very issue.
