How are you all passing inspection in MA with a Tune?
 

MA has been 'cracking down' in the last few years where if any of your OBD2 monitors show 'unsupported' they flag you and you have to bring your car to a state 'motorist assistance center' for them to go over it with a fine tooth comb. :thumbdown:

Even with catalyst showing supported and ready, it doesnt pass.

What tune and mods do you have and did you pass in MA?

I had to deal with this back in March, I put my stock catback + fp back on but went to get it inspected with catless UEL's and a OFT tune and it automatically got MAC'd. I ended up putting the OEM headers back on and flashed the tune back to stock, and drove ~100 miles for everything to be ready. The MAC center went through everything in my engine bay and made sure it was all stock but I was in and out in like 20mins

Did you do the recommended drive cycle or just drove normal for 100 miles?

I think I was one of the first to get flagged in January 2020. I believe you will need to run the older open flash stage 2 tune. The new tune is based off a European tune file which disables a few of the monitors. Or you can a O2 spacer on you catless header with a stock tune which i have done and passed.
