2g guys with widebands, chime in

[razrman8]

:Alright, first and formost you may be questioning why this is in the hangout forum. Well I feel that my understanding on this is just being overlooked. And I just need some ideas. I am trying to log my Eugo with link. From everything that I have gathered, this wb isnt the best to use for logging in the first place. Anyway, I have the 0-5v output wired to the rear o2 pin on the ecu. So why wouldn't I be able to log through link. Somebody tell me what I am missing here. Yes I have searched as well. This is a covered topic, but I need an explanation

 

[Kyle_T]

uego, not eugo.

 

[razrman8]

Thats probably my first problem.

 

[ed1380]

analog output goes to ecu. the writeup will tell you what pin. then enable wideband simulation in eculink.

the ecu has to be programmed to accept a 0-5v signal on that pin. right now its looking for a narrowbadn signal

 

[razrman8]

So its going to the wrong pin?

 

[Big T-28 GSX]

So its going to the wrong pin?

No correct pin but wrong signal, you want to be outputting a narrowband signal which is then translated by link to wideband.

 

[razrman8]

So is it my nb sim??

Something wrong setup wise?

cut the wire for pin 75 and conect the white wire from wideband going there. In the config live tab click on it, then select ECU inputs. Select AEMR1 for the rear o2. Have fun logging. I have the same wb. BTW

 

[razrman8]

Ok, I did. But I am getting a steady 9:8 while driving. Logging .02v at idle and 0 when throttling

So it is still not logging.

Is your wideband gauge (if you have one) reading correctly?

 

[razrman8]

Yes, I am getting good readings off of the gauge. But it wont log.

 

[ed1380]

what was the color of the wire that you cut?

 

[razrman8]

White, pin 75

 

[snowborder714]

Post up a log.

And you're positive you ran it to pin 75 and not pin 76? They're right next to each other and both the same color - white.

 

[razrman8]

Log posted. Im positive, but I can check again.

 

[Kalub]

Make sure you wire in your white 5v output from the gauge to the ECU. Then setup your DSMLink correctly and it should log fine. I have mine setup to act as my narrowband as well as my wideband.

And where physically is the AEM sensor?


Everything in link is setup properly.

 

[razrman8]

Rear o2 bung. I am getting fine readings on the gauge, just will not log.

 

[snowborder714]

If you still have the stock from o2, I'd turn off the narrowband simulation so that your car idles ok. The rear o2 spot is way too far back to have it try and simulate the narrowband.

Try checking the "Lock rear o2 voltage box" in the ECU Inputs tab and see if that fixes it.

If not, it's got to be in the wiring. Either the wrong wire from the wideband was put into the ECU, or you put it into the wrong wire at the ECU.

 

[razrman8]

Ok, I'll give it a whirl.

 

[Kalub]

It's a AEM UEGO Digital WB that you're trying to log right? That looks like this:

Why do you have it setup as a "AEM Wideband Gauge R1" in ECMLink? Make it look like mine. I have the same gauge.

 

[razrman8]

Brian, heres locked rear o2.

Setting to the different wideband gauge didnt help either. Just showed steady 10:0

 

[snowborder714]

I still vote there's an issue with the wiring, partially because your Front o2 sensor is now reading 4.35v.

Try switching the ECU input to the front o2 and see if you can get it to log at all. Also, don't be afraid to try all AEM options (I think there's 4-5 of them).

 

[Kalub]

I had to cycle through a few of the AEM options to find the right one as well. As long as you're sure you have it connected to the correct pin, and they are easy to get confused it should log just fine.

 

[razrman8]

Alright. It does sound to me as well like it would be a wire problem. I have checked and check. But I'll check again tomorrow. It's getting too late in the game for tonight. That would make sense. Believe me I am trying what I can. Though, changing those would be to try and make link and wb are reading the same, correct?
