Aem wideband completely innaccurate

I'm using an AEM UEGO 30-4100 with the PID recommended.

I have it wired to my egr position wire....

The numbers are way innaccurate. It pretty much sits @ 14.9 on HPT but moves all over on my AEM gague.

Anyone else have this issue?

It's easier to adjust/check with the key turned forward and car off. May have to run it a bit before you do that so it's not just reading air or play with it.
 


I honestly don't think I've ever found a formula online that has actually worked for me. I've had to figure them out for myself.

None seem to work for me either. How did you figure them out?

My afr gague is anywhere from 11-16 when I chop the throttle... HPT moves between 15.2 - 15.5

I give up :(

I have absolutely no idea what most of this means lol but I'm going to hook my wb up to my dhp whenever I get my motor swapped. Do I have to jump through the same hoops?
 


Wow. I am a moron. I hooked up to the wrong wire on my wb sensor.

Now working perfectly with the +9.4 parameter.

You have to do some math and figure out your voltage offset.

For instance, my LM-1 had a 0-4v output, but HPT reads 0-5v. I had to adjust it for that.
 
Just command. Voltage in your wideband software with key in acc engine off say u command 2.5 volts then open up hptuners software and see what you read
 


You can't program the wideband voltage slope with arm? Wow well you could always use a volt meter and compare the readout to your HP tuners reading to get the same result
