Ok, well guys I have a few questions. And before the trolls get on here about searching I did. Here is what I found. https://www.evolutionm.net/forums/se...rchid=13026502 . so I still didn’t find the answers to my questions. I am planning to install my AMS downpipe and test pipe to finish my exhaust. But I want to do my wide band with the downpipe out.

My questions are:
1) A lot of people are saying that it is not a plug and play sensor. True?
2) Call AMS today for some help and they said that I need to have a gauge to allow the wide band to work. If the wide band goes
To the gauge then what goes to the ECU?

I know I am new to this tuning world. And I want to do this right and also learn. So that is why I am asking. Want to do this right NOT RICE. thanks for your time guys!

 

I'm not sure what you mean by plug-and-play here. The AMS downpipe has an extra bung for a wideband sensor, so no problem there. The wideband sensor and gauge will need to be wired up, not exactly PnP, but no big deal either.



The gauge for most equipped widebands will have a +5V output that can be run to the ECU.

 

what goes into the stock 02 connetor? the 5+ out of the guage?

 

wideband comes with its own sensor, no?

 

What are you trying to accomplish? Just setting up a wideband and gauge to have in the cockpit? Or do you want to be able to log as well?

 

This, You get a sensor with the widebands if you get a standalone model (such as aem), you put the sensor in an open port on your exhaust and run a wire to the desired gauge location

 

Wow, this guy's confusion has me confused.

Your stock O2 sensorS (one on the downpipe, at the O2 housing location, the other on the stock cat which will now be on your test pipe) still go to the same places they were originally. The only difference to these is that you may want to include a spacer on the rear O2 sensor to avoid throwing a code and subsequent light on the dash. The first O2 sensor is used by the ECU to monitor AFR and adjust accordingly, the rear O2 sensor after the cat is a check to make sure the cat is working as part of emissions control. No cat (you having a test pipe) means that this O2 sensor thinks something is wrong with your cat and throws a code. Using a spacer means less exhaust gas flowing through the sensor tip and as a result the gas looks "cleaner" and no code is thrown.

To get a wideband running to display your air-to-fuel ratio (AFR) on an independent gauge, you must purchase said gauge and a wideband O2 sensor that goes with it. You will now have 3 O2 sensors, the two stock ones and one specifically for your gauge.

You route the wiring from this new O2 sensor directly to the gauge, and from the gauge there will also be inputs for power, ground and perhaps a dimmer so that when headlights are on, the gauge is less bright since at night time you don't need blindingly bright light to see, but in day time the brightness from sunlight might make the gauge hard to see.

 

there are 2 holes near the bottom of the downpipe where the test pipe connects. they are both for o2 sensors. one is for the stock o2 that will run back to the ecu. the other is for an optional o2 gauge (which you should get) that will run back into the interior of the car in order for you to monitor your afr readings.

heres a how to. https://www.evolutionm.net/forums/ev...tallation.html

 

DING DING DING. ok thank you all. I understand now. sorry for the confusion i caused others. lmao Total of three O2's.
Kool so even tho we hook up a wideband, the ECU is still only seeing the factory O2?

 

yes. you maintain the stock o2 sensors that go to the ecu and you add the o2 sensor that comes with your wideband/gauge (the ecu has nothing to do with the wideband o2 sensor).

if you're confused with what you should get (or something that has the complete package), check out the AEM UEGO (about 200 bucks). if you get that then all you'll need are wiring skills or find a buddy that does.

 

To add confusion to this, a wideband like the Zietronix has an option to wire an output in a simulated narrow band to your ecu - so your wideband could replace one of the O2 sensors that your car sees. This would allow you, for example, to tweak the stoichiometric point that the ecu is programmed to maintain up or down, depending on your needs...

 

Bringing back the thread since i'm a newb and a little confused as well.

So correct if i'm wrong.

I wanna have a gauge(preferably analog - i admint for looks) for real time monitoring and also computer/evoscan logging. So what i need to do is pickup the following a Wideband kit(which includes the gauge, controller, and sensor - e.g. just like the AEM/Innovate). Have the sensor run from the o2 bung to the gauge. and then use the 0-5v analog output on the back of the gauge to the computer. That combined with a tactrix cable should allow me to log everything i need. But what is the connection from the gauge to the computer? is it a serial? how do you go about doing that?

Appreciate the help. this is my first wb so i've never seen all these parts first hand.

 

AEM sells the wideband AFR in analog now. It also has the logging wires like the digital one.

 

And what connection is that? aem's website just says "0-5v analog output included for use with data loggers and virtually any engine management system" - i dont' suppose that means USB. is it serial? do i need to purchase something else to connect the 0-5v from the back of the gauge to the computer for logging?

First wb so little confused.

 

Serial and you have to map the wires to the pins - that I believe is the same regardless of Digital / Analog.
