G-Sport Gen 2

[19Coyote]

Hello I’m looking for help on trying to set cat/evap/O2/rear O2 monitors to pass emissions. I have a 2019 Mustang gt: corsa headers catted with gen 2 g-sport cats (#85230),corsa extreme exhaust, corsa pro series resonators, JLT 18+ (120 mm) CAI. Car runs good no cel/check engine light.

Just an update will most likely delete this thread… just passed my smog and had to reset these monitors in order to for them to set. I am tuned by Lund Racing and the car was running good no check engine light after installing these cats and resonators. All I did was go back to stock (do not drive on stock file tune!), re-upload the Lund tune no changes made, no O2 defoulers, and no O2 extensions needed.
