Default O2 sensors tuned out...consequences?

I tuned my car in summer time high 100's.
apparently one of my 02s was out and they were just tuned out while i bought new ones, now its winter and im wondering if anything negative can happen by me still running that tune.

Front or rear O2's?
If front, the ECM has no idea what the A/F ratio is. Get them reactivated!
If rear, they only tell the ECM whether or not the converters are doing the job right. Not a big deal.

I second that they need to be fixed. Open loop is not perfect for every condition. O2s make up for that.

Thats what i figured, yeah its the front/up stream ones. I actually already have the new ones installed but i just have not had time to take it to my tuner which is 1hr away. And also cause he kept telling me it was fine to keep the car like that. Ive always been uncomfortable with it especially the other day when i raced a regular hemi challenger, u can see the thread on street racing section. I wont be doing any wot runs no more.

Your front 02 sensors don't do anything at WOT.

So if you have issue/problem at WOT, turning on the front 02 sensors won't fix it.
