I am getting this codes as well and I just went into the dealer in Feb to get a software update. I only had my DPs on for about a month and the code started showing up about a week ago.

Just order a BT Tool so I will try to reset the O2 sensors as Shiv has suggested.

I had a software udate and there are no more cel's

It seems that my O2 settings were too strong (50%). I reset the lambda adaption and set the Procede O2 Modifier setting to 100%. This got rid of the 2c31 code and gave me the cat conversion codes. I ended up at 75% as the final setting running the 2/23 stage 2 maps.

The only recent change is the addition of my Dinan CAI with a K&N filter included. Does anyone know if this would have caused the need to change the O2 settings?

Im having the same issues..im getting codes 2c31 and 2c6b..the car is running fine and not getting any misfires and havent gotten any CEL's...I cleared the codes the first time they popped up and then they showed up again a few days later. Im gonna try resseting lambda and A/F ratios if they show up again

Do I need to make my Procede O2 modifier stronger (lower %) or weaker (higher %), if I'm getting the 2C6C and 2C7F codes? Currently have it at 50%.

The new software is crap.
