I just got my tunercat software & have a question. I am putting in a straight pipe instead of the cats in my 94. What problems will I see from the second o2 sensor and how could I fix them.

 

You won't have any problems at all. Just add a second sensor bung and plug it in. Or you can totally leave it out. The PCM does not have a diagnostic code for that rear sensor and it will not cause any problems if its not there. Mine has been out for over a year.

 

Thanks TJ,
Thats what I thought,but it makes me feel much better that the info comes from you also.
