Resolved Wideband Alternative?

[yesItsdsm]

I was having a converstation with a friend of mine who tunes. He mentioned to me that there's and o.e.m. replacement O2 sensor from Bosch that functions as a wideband that can be had for a reasonable price. Sounds like a cheap alternative to buying an expensive wideband setup. Anybody ever hear of this? If so, do you know the part number or what car to buy the sensor for?

 

[marcmsj]

Your friend was mistaken

 

[c4uldr0n]

A wideband is more than just a sensor. Your car wouldn't know what the heck it is.

He's talking about going down to the VW dealership and picking up a Bosch sensor (if your sensor burns out) that does come OEM on their vehicles (some at least).

As stated, a WB setup is more than just a sensor....you have to have a means to read the output which is what the controller does (plus most have a 0-5v analog out for logging).

WB = 0-5v
NB (OEM for us) = 0-1v

I got excited when I read the title, but figured it was not real...

Whats the cheapest (most afforable) wideband you've guys used, not to thread jack.

 

[1gdsmraider]

aem uego wideband.

 

[FORMONTOYA]

I use the PLX SM-AFR, no display (logged through DSMLink) which can be purchased for ~$200.

 

[95GSXBLUR]

PLX M-300 About $315 w/ display and logable.

Or the new updated PLX SM-AFR as stated above.

The Innovative LC-1 can be had for fairly cheap as well. It doesn't have a display, you can just log it through DSM Link, which isn't a problem. Save money where you can, right?

I have an LC-1 paid under 200 for it. Easy to install and very configurable.

 

[crazy_skier]

the zeitronix is by far the best bang for the buck under 300 and it can log rpm egt (if you have probe) tps a/f ratio and if you purchase the boost sensor boost to plus you can log it in link i'm pretty sure and i read of someone re-writing the link program to have the zeitronix program incorperated into it

 

[daren_p]

To the OP, well your friend was half right but thats already been explained Pretty much all the WB's they offer nowadays are very resonable as there are more then a few models that start under $300. I believe the NGK unit has the cheepest price but AEM, PLX etc also offer some in the same range.

so a sensor like one from Innovative can be intergrated with the stock ecu and read thru a logger? Or would I have to get a controller for it?

Our ECU's can do nothing with a wideband output. It will always need a 0-1v narrowband input. The wideband reading is something you want to log in order to have a more accurate air/fuel ratio at wide open throttle and tune accordingly.

 

[bastarddsm]

actually you could probably run the 0-5v through a opamp configured for a 1/5 gain and the bias it correctly and run a wideband in place of the stocker and log it with our favorite method.

You know you have a lot to learn when someone post a paragraph like the above and you comprehend it as much as "Actually if the nano ions are charged properly, and the flux capacitor is fluxing, then you could log the lithiem ion particles movement verses the flying monkey formula provided by Einstein."

There IS a 4-wire Bosch O2 sensor that a few OEMs used that is a different type of wideband than the now common 5-wire Bosch. It is just a normal 4-wire O2 sensor built to a higher quality standard with a transfer function that takes inputs of O2 voltage from 0-1volt and the impedance of the O2 sensor heater and spits out Lambda, which can then be converted to the AFR of whatever fuel ratio you're using.

MoTeC uses these with their M4 and M48 ECU's: http://www.motec.com/definitions.htm#4 Wire Wide Band Lambda Sensor

A+ that's a cool Motec link. I forgot all about Motec.
Side note: Champaign, Illinois!! That place f-ing rocks! Rock Fest two years ago I flew all the way up to see HUM play at one of Ward Golling's bar's out back. Great show and very nice people.

So whats the most cost effective wideband solution? I'm getting DSMlink this summer so what would work with that?

The innovate LC-1 costs $189 on extremepsi and can be wired directly into the O2 signal and read by dsmlink.

 

[ThingyNess]

Add another vote for the Innovate LC-1. Mine works great, and it's nice and cheap. If you need a gauge, get a voltmeter for $10 from an electronics store.

Thanks

This sounds like the plan for now.
