Do the o2 sensors have to remain in the exhaust for this code to not display, I was under the impression that they were completely turned off, is that incorrect. I recently put in a wideband and removed that sensor and began getting the code.

I currently have a 7193 predator running version 2.07. It does not have an air fuel ratio reading on it which makes it basically worthless for tuning WOT.

It is running the 2.xx version and the previous owner informed me that if I planned on adding mods like headers or cai that I should not try to update it to the 9.xx version. My question is what are the functions that the EPA made ...
