Wideband Sensor

[ArcticFox]

So, I am seriously considering a wideband sensor. I found this one from PLX
http://www.plxdevices.com/M-Series_productinfo.htm

What are you guys running? Links apprecaited along with any feedback on different models, differences between them, better this or that, etc. ...Tim

what is the main pupose of this?

OMFG...nobody here knows WTF a wideband is for? I need to find another forum! LOL.

It is also known as a LAMBDA sensor. It is used to determine real-time air/fuel ratios. Real important for somebody who does his own tuning....maybe with Conforti's new DME editor (to be released soon), or for those with forced induction......club racers who are tuned ion the edge, etc.

I am not 100% sure about this, but I don't think a wideband sensor will work with the factory DME. I thought you need a stand alone engine management system to utilize this.

Do you already have a tec lll or similar? If so, contact Vic Sias, www.siastuning.com, he would know all about that.

it's not for interface w/ the factory dme. what it is for is to allow the driver to monitor the car under certain conditions to make sure it's getting enough fuel. it's a great tuning tool when you can datalog to figure out what areas of the dme map need to be modified.

i don't have one in my car since i stopped modding my m3. but just about all my customers are getting the new aem unit since it's easier to read than a standard digital number output.

Call me, we started to use them with the Motec, and then went a different route. When I say brand new, I mean brand new!!!! Jay

Hey Tim, will that work with the Unichip? I was under the impression that it would only work with a stand alone ie. TECH 3.

I aint insterested in making it work with the DME. I have an O2 bung ready for plugging...lol. I am just using it to read AF ratio, thats all.

Jay, I will call you. Tim

So how are you going to know what AF ratio is optimum(and safe) with your cars setup? Are you using a dyno to tune and establish a base line that makes the most power and then tune a little away from the edge for safety's sake? That's probably the best reason to have one.

haha bung... i don't know why, but i've been laughing at dumb things

the aem wideband gb is still up isn't it? i'm not familiar with wideband set-ups though, what's the going price?

[ArcticFox]

I have already dyno tuned it with a Motec. However, with Jim's new DME Editor coming out, I wil be able to ditch the piggyback computer and "do it right". Thus, I want a wideband for tuning on the dyno and "checking it" on the street, under "normal" conditions, not dyno conditions.

As far as optimum ratios and how will I know....well, as long as that mo fo aint lean, it should all be good. Of course, it will be dyno tuned first....but then, maybe some street tweaking.
