help with UEGO

hi
I would like to know how can I read AFR on a aem wideband gauge without using o2sensor but via AEM ems 1313U
at this stage I use AEM ems uego that include o2sensor
and AEM wideband gauge using o2sensor too but
both do not read same AFR

cheers

There should be no difference between the two. The sensor reads oxygen content in the exhaust and it should not matter which sensor or setup youre using. As long as the calibration is setup right and the sensors are functioning properly it should be the same reading or very close to eachother.

I have the same quetion. I tried tapping the white wire from the gauge controller to pin 76, but i beleive pin 76 on the 1313u is not active because of the AEM internal UEGO unit. I am sure there has to be a way t send the signal from the 1313u to the guage controller. can someone who has any experience with this please help us? thanks!

i bought my box (1313u) used, and it didnt include the front O2 sensor that is supposed to come with it.

I use an aem wideband gauge, and I did however use the bosch O2 sensor that comes with it and screwed it in my test pipe. I spliced the white wire to pin 75 or 76 (cant remember). and only look at rear O2 afrs. they are dead on when logging and on my gauge

go to aem's site and look up the wiring chart for the 1313u, their are two pins for 02: one for O2 #1 and one for O2 #2. you're gonna want O2#2 if you're not using the ems sensor but the wideband sensor.

i hope this info is somewhat helpful, id be willing to clarify if need be. just pm me or ill check this post later

That's exactly what I was going to do. Just didn't know if anyone had done it yet. Thanks!!!
