MA State Emissions - Look Inside
I have heard members on this forum say they run long tube headers and a tune without any emission problems in MA.
I have just a V5 tune with stock headers and failed state inspection due to cats not being o/supported. I have had this tune for 2.5 years and had no issue in 2015 with mod tune at time of inspection. However, fast forward to this year and it failed as the state fkagged my car last year but passed. This year it was rejected and car was flagged by the state so I need to go to an independent state inspection first before I go and get a new sticker.
Apparently, V5 tune to get throttle blips cats are turned off. I already miss the V5 tune as I flashed to stock so I can get sticker.
Mpral of story flash car to stock prior to getting state inspection if you live MA.
Happy Modding

The v5 tune doesn't turn off your o2 sensors just so you know. My car failed inspection in NY, so I bought the EC V5 tune, uploaded it, and tried again. Monitors set and passed with flying colors.

I guess I misunderstood them then. Because when I got the tune I specifically asked that the monitors remain untouched and they said something to the effect that's already how it is done.
How old is your tune? Have you updated it at all?
Could be that I asked for the monitors to be untouched that they actually tinkered with my file. Regardless, very easy for them to do if you'd like to keep the v5 on and still get through an inspection.

I asked in speaking with Jerry he told me having not monitors on in V5 tune aids in throttle blip noise. He told me that if I wanted not ro have to reflash he could give me V4 tune as cats are on with this tune. I prefer to have V5 noise
I just wanted to give folks a heads up. Because now I have to get a separate inspection during the week....ma sucks.

I can't understand anything that's being said above.
For anyone who wants Cliff Notes on the above, flash back to stock file before bringing your car to be inspected. It's the common-sense thing to do anyway.

Basically, tunes disable your o2 sensors/o2 heater so you don't get codes or CELs on your dash. However, that means your monitors will not set to ready for inspection purposes. You will fail inspections if the monitors are not ready... However, you can also have EC (or whoever) write you a file that does not disable the monitors and just leaves them alone, allowing them to set to ready.
I ran my car through an inspection with the v5 map uploaded and had no issues.

Don't install headers unless you want to swap them out.
I have already been down this road with a previous car it sucks.

Why would the car be flagged if I have functioning cats and o2s? MA only does a scan as far as I am aware. I am not running one of these off the shelf tunes with added backfiring that would be disabling anything.

Based upon passed experience this does not matter your cats can be turned on and still fail as the state knows what your fuel trims should be for stock along with o2 levels.
Once you mod a vehicle the pcm levels change therefore you will have an issue, generally in the 2 year.

Interesting. I have had no issues with my tuned C300 in the past but of course that is a very different beast. I will have to ask the guys at the shop where I'm having the headers and tune done (BrenTuning in Charlton) as the owner himself ran a 2010 with headers for years. I would also be interested if other members in MA have experiences they can share here.

I'm from Boston and litteraly just was on the phone with a friend that has a e55 and could not pass because of o2s.I had kleemann tune on my e55 and it shuts off i2s in a whole different epprom and the monitors work and pass with scan tool.his car had a euro tune and had them disabled.
Here is my issue now.my c63 is stock and the dealer did work on the car and now won't complete o2 sensor.everything else will pass but its been 3 weeks and no luck completing it.
My long term fuel trim on bank one is all over the place it will go from 15 to 18 to 16 to 19 etc and I think the car is stuck trying to figure itself out.
I asked the dealer to change o2 sensor but they said it's normal.

You buy it new or used? If used, you sure it's stock? I've said it before that a lot of people that buy second hand c63's end up with a car that is tuned and they don't even know it.

You have to make sure your car is properly warmed up and all the sensors are set to ready, before taking your car in for inspection.

The issue is that coding out the cats, while reported as PASSED by some software, actually makes them come back as UNSUPPORTED. This means that this component is not installed or tested. This is a red flag for emissions testers. You might pass one year, then get hit with a MAC inspection next. Dangerous business, and the restrictions are getting tighter.
