So, I have searched and read all I can to try to perform this and I am having no luck...

I have my wide band tied into the factory rear o2 sensor wire and Evo Scan is reading voltage from my AEM. I disable both the settings in EcuFlash, upload the map and the CEL goes away. After about 2mins of running or and ignition cycle it comes right back on and it throwing o2 sensor codes. This is driving me insane!

Thanks for any help in advance.

 

did you turn the REAR o2 off in options ?

 

Am I looking in the wrong place?

 

yep
its in the ECU options set #2 map change to 0 from 1

 

Disabling just causes that cel/ses light to pop on almost instantly.
Unless you have a bad 02, doubtful or massive exhaust leak.
Had exact same issue, try a bung extender/non fouler.
Worked like a champ. It should do the trick.
Good luck with getting it straight, I hate that ses light staring at me.

 

you can disable that CEL/SES light as well

 

Yes but I don't think you can pass emissions.
I prefer to fix the problem, then do a short cut.
