ECMlink AEM WB and ECMLink

[jed344]

I have tried almost everything i can think of with no luck. I have a AEM wideband installed in my car in the front o2 sensor location the gauge is set to p04. The problem is i cannot get it to even log to ecm link no mater what type of gauge i pick or even liner wb it will not do anything accept sit at max rich value on ecm link and narrow band simulation will just sit at .02v. Any ideas? the gauge functions perfectly itself.

can you give us a little more information. which AEM wideband? which version of link? And as always, with any Link-related question, you should post a log

the AEM eugo digital wideband. i am running V3 with latest software. Ill grab a log later but it just acts as if there is nothing connected to the front o2 sensor input even though i have the white wire off the eugo taped into it.

Did you specify in link that it is in the front o2 input? Also once link is reading it you can put it back on p0 and simulate narrow band through link.

i have it specified in link that its hooked to front o2 i just took a idle log will post it up. The car also will not enter closed loop operation and it does throw a code usually for this. Is that because there is no front o2 so the car does not understand the crossover point?

lets see if this log will post ok.

ok, after reading through the manual for the Uego you should have it set to P0, not P4. it appears that everything is setup correctly in link. However, I would recommend using the pre-defined Front O2 pin assignment for the AEM Gauge. beyond that, I would ask for another cruise log, if possible?

Already tried that p0 and p04 today aswell as all predefined AEM options in link with no results... i even redid my ground wire so the aem is grounded by its self to a chassis ground im really out of ideas now. Honestly i can tune my car by looking at the gauge for A/F i just want to get the simulation set up so my car wont run in open loop all the time my millage is really hurting right now.

edit. i turned off the narrow band sim and set the pin back to stock sense its on p04 still no o2 sensor voltage shown but car was going in and out of closed loop now im still confused though log is included just a short cruise.

any ideas? im lost car is still running rich while cruising around high 12's low 13's in a/f while in closed loop.

did you ever get this resolved?

Might have cut the wrong wire. I've seen it happen... Your not showing any voltage on that input so either you have it going to the wrong input or there is no signal at all... check your wiring and set that W/b to be captured on the Front o2 again... As well You can unhook the sensor from the harness and it should default to 14.7 you can check inputs for it as long as the gauge is set to output the normal 0-5v. signal.

That is if you haven't sorted this out yet... .
