Let's talk widebands

BurningRubber · Jan 24, 2010

Who likes what, and what is affordable?

I know there are 1 and 2 sensor widebands. 2 sensors would be nice, but not mandatory if the price gets jacked way up. One could always switch banks in a matter of minutes.

I am looking for something that is going to be very accurate. The flash/bling factor is not a concern as long as it works well. I want to be able to keep tabs on what's going on when I am spraying, and I want to tune the car myself with my Diablosport rather than have someone else do the work.

How hard are they to install? I am not great with wiring, but I learned a bit while installing my nitrous kit. Got to start somewhere.

aem is very good, innovate are good as well. havent tried the rest.

PLX gauges are the best

AEM UEGO is the best kit in my opinion, and too cheap to pass up.

I know a lot of people tend to go with either one of those brands. I have heard the AEM UEGO kit is great.

Gauges, or a whole kit?

That is what I was leaning towards also. I have seen them for just under $200. Do you have one, and if so, did you install it, and how hard was the install?

I have an AEM UEGO in my 1999 GT. I got mine brand new (but just opened) for $180 locally on craigslist. The install wasn't bad at all, it comes with complete instructions. The hardest part is welding in a new O2 sensor bung into your exhaust, and postioning it correctly in the exhaust stream to get an accurate reading.

BurningRubber · Jan 24, 2010

Sounds like you got a good deal.

So you need to weld a new o2 bung in, you can't use either bung for the rear o2 sensors?

Yeah, I believe the computer needs all of the stock O2 sensors in order to run correctly and not throw codes, but I could be 100% wrong on that. In any case, 99.9% of people I've talked to with the UEGO kit have welded in a new bung. Here's the instructions in .PDF format if you want to check them out before buying.

The item number (if you're looking to buy it on summit or something) is 30-4100, by the way.

If you have your rear 02's shut off in the tune you can use a rear 02 sensor port.

I have the rear o2's turned off, so as long as the bungs are the same size, it should work...

Thanks for that link, those are pretty clear instructions.

Sure do, that is what I was hoping to hear.

AEM uego here also. great gauge at a great price!

install is simple. IIRC you only need a switched power and ground. i'd get the serial cable so you can datalog with it

lang williams · Jan 24, 2010

I may be wrong but I thought the further down stream in the exhaust the less accurate they are.

That is pretty damn simple.

That is correct. As I understand it, the tail-pipe clamps that most shops use to check the A/F ratio can be up to 1 point off since it's so far back.

not trying to jack the thread but would you trust a ebay wide band gauge like this?

I picked up some autometer gauges the other day at summit but may take them back for this:

that is true, but when your on a dyno and don't have a wideband they stick it in the tailpipe, this would be far more accurate then that since it's not that far downstream

links are dead. i've never seen a generic wideband gauge

I use the AEM UEGO

midnightdriver · Apr 12, 2010

I have some ?'s too.

I wanted to run dual wide bands, because I want to keep taps on each cylinder bank. Would I buy two gauges, like 2 AEM kits or i looked at the FAST dual kit but that is not cheap, $480 plus.

I like that the fast can data log and display but do i need to data log?

Can I install a switch to turn the wide band on and off instead of using the ignition switch, already have a switch by my traction control button that was installed for the previous owner's bass that is no longer used?

Lastly can i install the wide band between the factory cats or should it be installed after the cats?

Thanks
