Help tuning rear o2 sensors off

Hi,

I installed long tube headers and deleted the cats on my 13 5.7 challenger. I am running front o2 sensors of course but want to leave the rear ones out. Can someone help me with what I need to do as far as turning off the rear o2s/running without cats in my tune?

Thanks.

Go into the Fueling Tab, and then click on the Oxygen sensor sub tab. On this page you'll find a section called "Feedback" and under that it will say "Closed Loop Enable". If you look under this heading, you'll find an input box that's labeled "ECT Rear"... Put 376 for your enabling temperature in this box. Obviously, it will never hit 376 degrees therefore your rear O2's will never enable. You're all set.
