My car changed the Header to a no-catalytic model.
I use MAP fuel tables.
Should I use mode secondary oxygen sensor enabled?
Enable and disable How different?
thank you

I have a 14 Honda Civic ex with no cat and I had a Dyno tune done they was using the map for wot and I had my secondary 02 disabled and it made my check emissions light come on so I had to turn my secondary 02 back on and get a defuser cause the secondary 02 in my car I think is used to calibrate the miles to empty

What was the error code and from Help, About, what version of software was used to tune this?
