Hehe this is where my cluelessness kicks in
I assume that with a catted section 1 and O2 sensors, you could avoid a SES light, and possibly other engine codes (even with a high flow cat setup).
With a non-catted sectrion 1 and O2 sensors, there would be no way to avoid a SES light, and possibly other engine codes, because the sensor readings would be out of spec.
It's not so much a concern for emissions testing, as it is not wanting to drive around in acar with SES lit up and fault codes being generated.
I
want a tune to get the most out of the chagnes to the exhaust, but with a non-catted Section 1, I would
need a tune with rear O2 monitoring disabled to avoid engine codeds and an SES light.
Hopefully that makes (some) sense
