13+ ecu P0420,P0430

[Autox4fun]

Back story,
Had most of this/these mods on My 2011 Flex - others posts about that car... but switching from that ride into a 2013 Exploder. So major updates in the way of ECU abilities..

Exploder got a built engine (other posts) but lots of stuff got swapped over, and never had an issue with the 420/430 codes on the old set up.

PPE Catted downpipes installed from the flex and 4 new o2 sensors
reviewed for cracks etc, have not watched them in action as of yet, Build and driving - all of 150 miles on this setup


question for the 2013+ is this ecu that uptight?

Do I need to add defoulers?

I've seen other catted downpipes with them... fairly normal on this?

Not a direct answer but my post cat are tuned out for that reason, to avoid the issues and running mini cat spacers. Though in FL I can get away with it.

Can't say if the newer system is more sensitive though always questioned why we had an unmonitored post cat. As a part of the noise tuning of the resonator? Or Ford making sure it passed emissions. Not to hijack your question.

Who are you using for tuning?

I've never had catted downpipes to say lol.

I run the defoulers with mini cats in them from Amazon, work great

 

[Autox4fun]

I have ordered those and sent Brad some tune money lol

Haven’t ran defoulers with catless downpipes always had the secondary o2’s tuned out…back when nobody cared and nobody should but I get it, today is different
