What information would one need to purchase a wb02? There's alot of discussions about wb02 but no recommendations for products... Any suggestions?

 

Depends on how much you want to spend and what you are looking for. I don't think you really need one that logs since you can find Wideband o2 patches for many ecms so you can take the wideband o2 0-5v output and connect it to a PIN on the ecm to then have it outputted in the ALDL stream.

I would get one that has the following:

I would stear away from any wideband o2 controller that has a Non-Linear output (i.e. uses a table.) Problem is with a lot of Non-Linear O2 controllers is you usually only have a few datapoints that are known to make up the Voltage to AFR curve. You then end up have to interpolat a lot of the points for the missing values. So it could end up not being as Accurate as a Linear one.

Linear o2 controllers can have their problems too. I have a ground difference on mine so my AFR is always off by about 1 AFR. My AFR gauge says 14.7 and what I have coming out of TunerPro with the o2 controller hooked into my ECM is 15.7.

A friend had a TechEdge 2B0 Wideband controller and lived right up the road from me. So after having him show me it, I got the same one. I love it. Has all those features plus a bunch that I don't use. Just need to track down why the output is 1 AFR off from the gauge I got with it.

That is my 2 Cents.

 

How can you love it when there is a 1 AFR error? I'm thinking of a new rule: anyone mentioning a TE WB unit on TGO is immediately banned and their post deleted. For anyone that doesn't understand this, search the diy-efi archives.

gt500pwr, there are several WB's available that folks on this list have and have commented on. The two most common are the Innovate and Zeitronix units.

Sounds good to me.


The Innovative LM-1 is a fine unit.
While not released yet, NGK has one, for $299 now, and it uses a NTK (Honda) sensor. I have one on order, but it's still on backorder.

 

Yah I know the story... Sorry if I brought up a sore subject. I have a similar problem with other brands too. The voltage going to the ecm isn;t the same as the voltage going to the gauge. I have som sort of ground problem causing a difference. Any way sorry again if I brough up a sore subject.

 

I'm pretty much a novice at tuning as it goes around here but I have had a Zietronix for about 10 days now and so far it's great. Within 10 minutes of my first drive with it I realized that my tune under WOT was so lean that I have had luck on my side not damaging my engine.

 

Some great info, I appreciate the feedback. The WB seems to be the way to go so since i'm gonna start fresh might as well do it right.

 

What about using something like AEM’s Wideband UEGO Controller, and just disable the narrow band 02 sensor in the ecm? That way I'll only have the WB info which is want we're looking for and I don't need 2 02 sensors. Is that correct? What will I be missing out on? This is a nice 2-1/8" digital gauge and bosch wb02 sensor AEM : Programmable Engine Management Systems


Thanks

 

The LC1 is cheaper than the LM-1 and works great as well....

 

LC-1 Looks nice... will it hook up to the 8746 ecm? From the video I watched at their website it looks like just 1 wire to tap into the ecm. Will this unit replace the original sensor(narrow band) or does it only do wide band? Will I be able to log the AFR using a standard aldl or do I need to use the software that comes with it?
