I'm currently having issues in MA with inspections. My O2, CAT and EVAP state not ready.
Running an ESS G1 on my e92 M3
With an akrapovic evo exhause with the high flow cats on them.
Emailed ESS about the emissions tune and waiting to hear back

Quick update to confirm with the ESS emission tune files + minicats, I continue to pass VA emission with primary cat delete.

First passed in 2018, then in 2020, just passed the 2022.
