I recently had LG Pro headers put on my C6 but didn't have the o2 sensors at the time. I had stumbled on a post that had a walkthrough on how to disable them and did so with success. This is on an LS2, A6, 2006
Now I have the front two sensors in and working but they are still disabled via the the tune.
I do not want to reinstall the rear ones if I don't need too so question one is does this pose a problem to the ecm to only run off the front two?
Can anyone tell me the optimal way to enable the front ones while still leaving the rears off? I know the DTC's with Bank 1 need to be enabled again but looking for any additional help anyone can throw my way.
Sidenote if anyone can point me to that elusive post that I can't seem to find the correct search words that discussed this topic that would be great.
Thanks!
