2G Wiring aem

[Inkdlyfe]

How do I make the wideband the row signal to the factory o2 sensor wiring so it will reads to the em. Would I just tske the signal wire from both and put them together but not attach it to the narrow band or

In ecmlink you can simulate the narrowband and you will also be able to monitor 0 to 5 volts for WOT tuning.

Usually with the Aem manual it will tell you what pin to splice the wideband wires into. The stock O2 doesn't do much with the Aem.

Splice the two signal wires into the Aem, where stated and the aem will read it.

It's all covered in the install guide available off their website.

If you are using the rear location then you would tap into pin #75 going into ecu on a 2g and #74 if you are using the front location. Do you have ecmlink?

 

[Vor V Zakone]

It says aem in the title. So I'm not sure what he has.

 

[AllWheelTerrorTsi]

The wideband being an aem is what he is referring to I'm sure. I think he wants to simulate narrowband using his wideband but you cant without ecmlink or some sort of piggy back or standalone. Correct me if I'm wrong though.

I know my innovate has a yellow wire that simulates a narrow band signal. He should just be able to splice that into the ecu or whatever he wants to have a narrowband signal.

Most widebands have a simulated narrowband output.

Thank Donnie Kak

The post is also very confusing and is absent of grammar and spelling.

ok yeah so you can simulate narrowband without using ecmlink but instead of being able to log both 0-1 volts and 0-5 you can only monitor 0-1 volts. Still pretty useful though if you have a bad stock sensor. I wish I would've have gotten the x series or an innovatethough because my aem is inaccurate from what it logs in ecmlink to what it shows on the gauge. I know I can set it up as a linear wideband but I hate I have to do extra work just to log correctly. The new AEM, new Innovate and AEM x series all use the saem Bosch 4.9 sensor though so I didn't think the new aem would have the same exact problem the old aem widebands had.

 

[Vor V Zakone]

Yeah. My innovate mtx l in my 3000gt Vr4 has a 0-5 volt out put and a 0-1 volt yellow wire that simulates a narrow band. I'm surprised the Aem one doesn't.

Mine seems to be accurate. Considering it has a bad exhaust leak at the cat. Haha. It's time to go test pipe.

Basically I'm trying to get rid of my o2 cell it says no activity from o2 . So i figured tapping into the wideband will delete the cell im getting i dont have a link or anything like that right now when I get my turbo back on ill then be running a aem fic 6 which then will be intertwine with my wideband its self . Running my wideband in place of the narrow band seems to doing just fine 14.4 at idle and when cruising in 5th at a steady Rpm it's at low 13s some times high 12s I was just trying to get rid of my cell with out having another bug welded

The new aem one I have just has a blue wire that you tap into the ecu and basically hijack that signal and then it reads what the wideband is reading. There are five modes on the AEM I'm using P00 which is 0-5 volts and then in link I can simulate narrowband so its doing both for me. P04 is the setting just for 0-1 volts if you don't have link. My o2 sensor was bad when I installed link and my combined FT were up 30% no matter what my adjustments were then I saw my front o2 wasn't cycling so It was a no brainer.

Do you have anything that you can log with?

 

[Inkdlyfe]

So what pin would I tap into the wide band before was wired to the o2 wires not the ecu at all. And I believe it's pin 74 the all whire wire but that's where my tac is wired to should it go there to

Not I'm getting a adaptor to run it off my computer they said i can get a computer plug that the blue wire goes to so rifhr now I dont have a log

Do you have anything that you can log with?

 

[AllWheelTerrorTsi]

If youre in a 2g its pin #76 for front o2 and its pin #75 for rear location

 

[Inkdlyfe]

The rear one been deleted. So pin 76 anyone know the color code on that? 98 eclipse so its the big ecm not the 2 small ones

Can you not see images on mobile phone cuz it's says img won't do anything else

 

[AllWheelTerrorTsi]

I sent that using my phone and it worked fine but now I'm on my laptop and its just a small black square. I can post the url if you cant see the 95+ ecu pinout

http://www.dsmlink.com/images/forums/2GECUPinout.pdf

Now you should be able to click the link and see the image. The rear and front o2 are both white wires so make sure you cut and tap into the right wire coming from the ecu.

That's weird. I don't like how they do that. You can have both a wide band out and a narrow band out.

Here's the wiring for my innovate. Yellow = wideband 0-5 and brown = narrow band 0-1.1. That's what I meant earlier. I really love my innovate and was a steal at $80.

 

[pauleyman]

You guys keep talking about ecmlink. OP is 420a.

 

[AllWheelTerrorTsi]

Sorry. Ecmlink is irrelevant. The ecu pinout I linked is also irrelevant as that is for 1995+ turbo ecu's only.

420A pleasse

Your correct
