Is it possible to install a wideband O2 sensor in the stock position and have my stock ECU use it alongside my Air/Fuel Ratio Gauge using the same one? How? Maybe there is such a thing as a Wideband O2 with a "Y" cable??? Any Ideas?

 

i would not put a wide band o2 sensor in the stock location if that is on runner number 4, but further down stream like where y8 o2 sensors are.

both aem and higher end innovative wide band sensors support narrow band simulation, which allows you to hook up a wire from the wide band gauge to the stock narrow band ecu port

 

Agreed. Even if you can't weld, there are no-weld in bungs made by AEM. They use a drilled in hole and a clamp. Don't put it on one running, it won't be 'accurate' for the whole motor. Example, my cylinder #1 had a misfire and spewed fuel out my tailpipe. If I had my wideband on the #4 runner, it would have been reading just fine.

My AEM UEGO? or whatever it is, wideband, I believe supports narrow band emulation. I however, just kept my stock O2 sensors where they were and mounted my wideband elsewhere.

 

Mine appears to be at the end of the manifold. So,this is acceptable? Or is it to close?

 

I think that is probably fine, but mine is closer to the cat.

 

It's better to use both. Keep the stock one for the ECU, and add the wideband elsewhere (further downstream) and use its own gauge.

 

I run one under car as my primary, but yes it's an innovate wideband.
I don't currently run an oe narrowband at all.

 

This is more or less my suggestion, but obviously the other way does work.

 

A wideband suggestion is to have it at least 2 ft away from the exhaust port. Thats so that it gets a proper reading from all the cylinders.

 

Yea... Not even close :-) LOL!

 

i bought a bung off of ebay for 2 dollars and paid an exhaust shop 5 bux to weld it onto my down pipe. most widebands you buy new come with the bung as well, i know the AEM does

 

AEM does in fact come with one. I got a one of the clamp on style bungs that I'm going to try out and I'll post my results. It was on sale on amazon, $30. But I can transfer it to my new exhaust when I get that done in the next couple months.

 

The innovate MTX is $150 on eBay and comes with a new bung.

That's what I'm using in one of my cars.

 

i have the MTX-L i believe, i love it. self calibrating, easy to hook up, and you can buy replacement o2 sensors from autozone for 50 bux

 

Dang, I got my AEM for $160 and I forget what the bosch sensors are. Probably right at $50 or so from autozone. They came on quite a few different cars, stock.

 

I'm going to buy another one bc they're hard to live without.

 

when i bought mine the computer said my sensor was for a newer hyundai haha

 

"self calibrating"??? I thought ALL O2 sensor / air-fuel setups were just plug and play. Guess I need to do some educating/research... Thanks for the Info!

 

I think that has to do with them being run in an overly rich environment for too long.
