2G: Cant log AEM WB in Link V3

[RocCitySlayer]

So.. My car has been off the road for about a month now, Turbo blew and no longer wanted to spool. So since it has been down I have been straightening out a few things that were messed up on the car. Mounted the FMIC the correct way (prev owner had it retareded) Cleaned up a few things. Now I want to finally make sure that my AEM wideband is logging in link because it hasnt been. My question is, how exactly do I get my wideband to log in link? The gauge works, and is wired into the ECU but When I go into ECU inputs in link I cant get it to log. I dont understand why im having such a hard time with this... Any help is appreciated

Thanks, What would be the ideal ecu input to have to WB going into? And do I need to worry about setting up voltage for the sensor or no?

Depends on where you have the sensor (I don't remember where you put yours).

If you replaced the front o2 with it, then use pin 76 (front o2 input).
If you didn't and don't need emissions, pin 75 (rear o2 input) is a common one. Remember it should only be installed in the rear o2 spot if you don't have a cat.
If you do need full emissions, I'd still do pin 75 and just put quick disconnects on the wideband input wire, rear o2 input wire (sensor side), and rear o2 input wire (ECU side). This way you can easily switch back to the stock sensor when needed. This would require a 3rd bung to install the sensor to.


Yes, it'd be recommended to set up the sensor via voltage as the AEM is known to have issues with logging correctly in link.

I do have a cat but do not need to worry about emissions. And im pretty sure the sensor is in the rear. I have one sensor coming off the o2 housing and 2 more under the car right before the cat.

Also, how can I find out what voltage I should be setting it at?
This was on the car when I bought it so im not to sure of exact locations

Well, if both sensors in the rear section of the exhaust are before the cat, I have no idea what's going on there. The rear o2 just checks if the cat is working, so if it's before the cat, it won't work.

Maybe I'm wrong about them being before the cat. Its been awhile since I looked under the car. But could one of them be the Wb sensor?

[snowborder714]

Yes, most likely. But you need to check if it's before or after the cat for sure.

Thanks for the info
I finally got it to log. only problem now is its .5 off.

I still cant get my wideband to log correctly. When the car is running the gauge switches from rich to lean back and fourth. But when I turn the engine off and keep logging the gauge and link hover around 13.5
What is the problem?
By the way the gauge is a AEM 35-8460 uego wideband
