Hey all, recently finished installed my turbo kit and aem infinity 6 ems with the plug and play harness. i got the car idling but for the life of me cant figure out how to set up the wideband o2 correctly D:
I can get the car to idle but its pinned at 20+ A/F ratio. If i blip the throttle it jumps to around 10-13 and cant seem to configure the ems to read the sensor. I have the red cable to 12v ref, the black cable to ground and the white 0-5v ref cable plugged into the aux connector on the pnp harness. with a factory pin. when i go into the ems and go to the input fuction assigment i cant seem to get it right.. any ideas? thanks!

 

what sensor are you using? what wideband harness are you using?

 

Are you not using the AEM uego extenston harness?

 

There is analog in within the aux connector , but it is not mapped to wb02.

I'm not familar with AEM SW , but I would look into wiring in the previous post.

 

im using the 4.9 bosch sensor that comes with the aem x series and the pn 30-3508 aem pnp harness.. am i correct in assuming i can use the 5v ref "gray" pin on the aux connector and set it up in the aem under other input functions?

 

no i am not, im assuming it would be a hell of a lot easier with that harness huh

 

hrm sorry not familiar with that sensor or gauge setup. I believe that uses an external wideband controller?

I used this plug and play setup which uses the Infinity's built in wideband controller and it all plugged straight into the aem 30-3508 harness. The multi gauge lets you cycle through any value (ie: temps/pressures/boost/AFR/etc):

LSU 4.2 Wideband Sensor 30-2001
Wideband Wiring Harness 30-3600
X-Series AEMnet Can Bus Mutli Gauge 30-0312

 

so assuming this is your guage/sensor then according the instructions (https://www.aemelectronics.com/files...or%20Gauge.pdf) you should be able to just wire power/ground to your gauge and then plug the AEMNET connector to the AEMNET connector on your Infinity harness, you shouldn't need to use an analog input for it

 

Honestly, I bet AEM support could knock this out if you called or posted on their board.

Also, be careful using "Ref" when explaining connections. Ref is reference voltage. This can be thought of as the souce of power used with sensors most of the time, not their output.
