wideband o2

[nwbDSM]

I got questions about wideband. I'm currently looking at upgrading to ECMLink v3 and was also told that I should get a wideband. My questions are...

1. Some said that it can be used to replace front o2 sensor. Some also said that it is better to add a bung (about 2-3 feet away from turbo). Where exactly I should install a wideband o2 sensor?

2. Can a wideband o2 sensor be connected to the ECU w/ ECMlink v3?

thank you

The answer to question 1 is No it can't be put in the front o2. But, Some people will say yes it can... Read this Whole thread for a better understanding of why it's not a good Idea... .

Although their is one reason to place it in the front o2. It's to negate the effects of having a sensor reading a "delayed" o2 signal when using it as to stimulate a Narrow-band o2. But with a little work with the setting in v3link you can work around any issue you may or may not have.

The answer to question 2 is Yes Here is a link Click here and Here.

If for some reason you Absolutely have to put the sensor that close your suppose to fabricate a heat shield this way...

Thanks MY1GDSM. So, tell me if I understand correctly. I can still put a wideband in the rear o2 sensor, right. My car doesn't have CAT, by the way. If so, what do I do with the old rear o2 sensor wire? Sorry, I'm just trying to wrap my head around this. I'm planning to get AEM. What do you use on yours?

And I'll be the one to say plenty of people are running a wideband instead of the front sensor without problems, including Tom Dorris, one of the makers of ECMlink.

If you install it in the rear o2 spot, you'll just tuck the rear o2 harness out of the way. You will also tap the output of the wideband into the rear o2 signal wire so you can log the wideband in ECMlink.

Thanks snowborder714. This helps a lot. But, why can't I tab a wideband to the rear o2 harness?

One more quick question though, I read something about AEM wideband and ECMLink from HERE and am wondering if anyone is running into the issue stated in ECMLink site. I'm planning to get AEM and want to make sure that everything would go smoothly.

Any thoughts or suggestions.

sorry but quick question. Can the innovative Motorsports db gauges be used in ecmlink or does it have to be the lc-1's? Thanks

And I'll be the second.

After battling with the delay and other tuning issues (especially when using a simulated NB signal), it's worth it to me to replace the sensor every couple of years. With that said, I haven't personally seen one fail yet in the front O2 port. I've heard lot's of second-hand recommendations not to do it, but have never seen a true failure. YMMV of course.

Now that I think about it, I think OEM front NB O2 sensors fail more often in the factory location than WB sensors do.

And... @ "the Tom Dorris". Tom would enjoy that I'm sure.

You can tap a wideband into the rear o2 harness. Doesn't matter where on the rear o2 signal wire you do it.

Yes, the AEM is known to have issues with ECMlink. I don't know how well it works after following the writeup on the link wiki about it.

The DB gauge is just that - a gauge. You need the LC-1 as it's the sensor controller.

Honestly unless you have a sensor that knows it has a heater timing error theirs no way to know if their is a problem...Or if the sensor is reading correctly.

sorry but quick question. Can the innovative Motorsports db gauges be used in ecmlink or does it have to be the lc-1's? Thanks

The DB gauge is just that a Gauge that goes to a LC-1... theirs also a new Innovate gauge that resembles the AEM called the MTX-L that the gauge has the controoler built in like the AEM gauge...

Only problem I've seen is If you Log the wideband to the the EGR temp input on a 1g it won't read below 11.0:1 in the logs with out a buffer...

Thanks MY1GDSM.
What do you use on yours?

No problem,

I use a LC-1 with a DB gauge... Unless you meant what input I use... In that case it would really depend on you own application...

Overall I just wouldn't recommend a AEM UGEO...

I'll be the third to say you can absolutely run a wideband in place of the front o2 with dsmlink. I myself do it and I know many others that do it. If you are using dsmlink which has narrowband o2 simulation or you have a wideband gauge that has narrowband o2 simulation you can easily run the wideband in place of the front o2. The only problem I have heard a few people have is the wideband gets too hot in the front o2 location. I haven't had any problem with this and I don't know anyone personally that has I've just heard some people say that.

Oh got you. But can you get the db gauge and the lc-1 sender unit to hook it u to the ecu? Or which lc-1 would you recommend?

 

[snowborder714]

Yes, you can use the LC-1 to feed both the gauge and the ECU for logging. Go search eBay for an LC-1 kit as they have had the best price recently. Just pick one of the higher reviewed/top sellers to buy from.

Ok thank you i will check that out. Thanks

fwiw im running the AEM in v3-- works good thus far
