Okay I hear of COT delete when you are tuning. for the life of me I can't think of what COT stands for I tried to search but the search isn't working.
I know that I have to know what it is and just can't grasp it as a acronym. And it's bugging the **** out of me.

 

If I remember correctly....
COT = Cat Over Temp or something similar......it dumps fuel into the exhaust to cool the cats, don't need it if cats are no longer there.

 

Dont need it if cats are still there. Just drive like a sane person and you wont melt anything. Infact the stock tune is probably too rich to kill the cats anyway.

Regardless, disable COT so it dosnt mess with your WOT fueling.
