AEM UEGO only reads 8.5 in Link

[thejollyrancher]

Hey guys,

I drive a 1g TSI. I recently got an AEM wideband and it reads perfectly on the gauge, yet when I open dsmlink it constantly reads 8.5. I tried setting it to linear wideband as well and got a similar result. I believe I have it wired correctly, the white wire is connected to the stock white wire which is going into pin 4 of the ECU. Whats causing this and how do I fix it?

Thanks!

I followed that exactly and no dice.

Did you read through the whole thread and then on to this link?

Post a log.

Ill go through that link and set the calibration, however all the videos I watch at least have the wideband logging SOMETHING before calibrating it. Ill give it a shot anyways and post a log ASAP!
Thanks

If you didnt calibrate it then....

It's not even that its not calibrated, its showing no change in values at all like the ECU is just getting a constant raw voltage. Ill calibrate and post a log to be sure !

Here's a log

So I took out a multimeter and measured the voltage I get at pin 4 and it definitely fluctuates. The raw voltage DSMlink reads however stays at either .04 or .06. I am getting a steady voltage at around 2.3 volts at idle and it fluctuates as my gauge does when I give throttle. What could be causing DSMlink to read like it is ?

You don't have it set in "Narrowband Simulation" do you?

On the back of the gauge, the rotary knob should be set to P0 for logging purposes to ECMlink. If it is set to P3 or P4, that will cause it to send a 0-1V signal, which sounds like the problem you are having.
