I have hptuners and would like to delete my rear o2's but cant find the "COT"

 

COT = Cat Over Temp protection. It adds extra fuel when the ECM thinks that cats are being over heated, typically around 11.70. This has nothing to do with the rear O2s, you need to go under the Engine Diagnostic tab and look for Pxxxx code with B1S2 or B2S2 then uncheck and set them to -3- No Error Reported.

 

Thanks, I will try it.

 

Thanks George it worked like a charm.
