Just wanted to chime in as I just went through mass state inspection
I originally had my tune with cold start off and cat monitor off,
However this wouldn’t allow my fuel, cat or heated 02 monitors to run and become ready. The state of mass only allows one monitor to not be ready
After driving around fiddling around and wasting fuel to try and make the cycles complete
I reflashed the car BM3 Stg2 +
With all the OEM emission controls turned on including cold start
All the monitors were completed and ready for inspection in 20 miles
The car is running Dorman help part number 42009 as a rear o2 spacer on the VRSF 🐈 less DP
2018 340 xdrive is the car fyi
