So I have an AEM Wideband and I have been running the 0-5v output to d14 (o2) to tune with. However I was wondering if it was possible to use the wideband to run in closed loop? I have set it up and yet nothing happens, no short trim or long.

I attached a screen shot of my settings if it helps any.

No you cannot run in closed loop from a wideband signal. It will not work. You can only run in closed loop from a narrow band signal. The AEM can only output one signal at a time. This is why we only recommend the PLX widebands (they have both narrowband and wideband).

I understand the issue with the single output on the aem. I just thought that using a wideband signal could somehow be more accurate in keeping a target AFR. I guess Ill put my narrowband back in and run them both, no biggie.

im not really understanding this close and open loop. i tryed to read about it but still doesnt make any sence to me at all. Can someone on here put it in a ABC for me?

I am setup the same way. Have the AEM in d14 and no stock o2 sensor hooked up. Will there ever be a future upgrade of s300 to allow the wideband to be used for closed loop in its place?

No. This is why we only recommend the PLX widebands as they have a wideband and narrowband output at the same time.

Thanks for the info Spunkster. Luckily my other friend will be going the plx route after learning this.
