2G Connecting AEM wideband to ECMLink

[TSiBOLO]

I have my AEM digital wideband all wired up and working properly (as far as I can tell). The sensor is installed on my test pipe in front of the rear o2 sensor. I am trying to tune for speed density right now before I throw in ID 1050X's, Fuel lab FPR, AEM fuel rail, comp 102s and kiggly SS valve springs. On link it is idling pretty smooth (stock 450s and Walbro 225) but I am still not comfortable to go out and drive. So if anyone can help me getting my wideband logging it would be much appreciated! Thanks in advance!!

You need to disconnect your rear o2 and wire the 0 to 5 volt wire from your wideband to pin 75 on the ecu. Then change the pin settings in dsmlink accordingly.

Don't I have to make a switch for simulating narrowband or something like that?

AEM doesn't seem to play well with Link so you have to set it up as a linear wideband function and calibrate it yourself.

Okay, thank you so much!

which AEM is it. .. also, you can simulate narrow band, it makes tuning easier. AEM hooks up to dsmlink just fine.

is it the one that the sensor hooks to the gauge and then the white 0-5v wire comes from the gague?... because I have that in one of my talons, and the white wire to pin 75 works great. make sure to clip the existing wire and then have only the wideband hooked up to the ecu.

I have the UEGO gauge with the LSU 4.9 sensor. Don't know if that is good or bad.

yeah, same one i have in the talon. cut the existing wire at the ecu to pin 75 (leave enough to connect the new wire to the ecu. solder the white wire from the gauge (0-5v) to pin 75 on the ecu. I'l check the exact settings in my dsmlink when i get home

Awesome! Thank you!!

in the ecu inputs tab --> pin assignments for datalogging --> change rear o2 to 'AEM Wideband Gauge'
under the pin assignments for ecmlink, change wideband to rear o2.
click 'save pin assignments'
click copy to ecu

enable wbo2 simplation, switchpoint 2.49 volts.
startup options 4 secs delay, 0.0 for the bottom 2.

under the maf clamp tab, enable the 'use manifold pressure (MAP)' checkbox

copy all to ecu

Mine idles at 15.1 AFR

Here's some info on it:

U don't need to simulate if you are still using your front O2 sensor. There is a great video on YouTube by gofer that shows you how to get it to match up with link.

I have is calibrated and idling at 14.7! Followed Corey Jenson's detailed YouTube video. Worked perfectly, just don't forget to uncheck 'Lock in Openloop'. Haha
