2ndary O2 disable?

[IanB]

I was asked this question, and did a search, couldn't find an answer. Does HPTuners allow you to disable the 2ndary O2 sensors to allow for running no cat, and throw no codes (off road use only of cours)? The question is specific to ecotec J-body cars ('03+), but any info would be appreciated.

You can disable the SES light (off-road use only, of course).

You can disable the SES light (off-road use only, of course).

But is that going to negate the negative effects that failing the emissions check has on the performance of the engine? When a code is thrown, does the ecu not default to a rich "limp home" type of program?

When disabling the SES light, you can also disable the error. No error would be detected.
