MA Inspection FAIL - refer MAC

Question, for the others that had to go to the MAC, do you know how the inspection with the "specialist" went? For example, do they just scan the car, or do they visual everything: cat, EVAP, EGR, etc.?
Per the advice, I'm probably going to re-install the EGR and EVAP and revert to stock exhaust, cat, airbox, and set ecu to stock parms for the most part so the car is legit. Some day when the car is exempt or at least not my DD I will think about modding again, but this is such a PITA and a hassle it's not worth it... Another option is to buy a property in another state that is still reasonable and register the car there.

Hi,
I kind of wish I hadn't messed with it.
I got a new ported IM from MAP. People had posted benefits of removing EGR and EVAP, such as cleaning up engine bay and possibly reducing the amount of crap getting recirculated into the IM. Not sure on other benefits, but I had this done while the IM was getting replaced anyway... I remember reading about EGR block-off kits for DSMs as well, so it wasn't a new concept. Not sure how much actual benefit if any, especially considering emission inspection issues.

So:
confirmed pass with 9417015 on a 9417008 car?
confrimed pass with EGR/ EVAP enabled and functioning on V7 (9417015)?
any idea if SD would cause any problems from an OBD stanpoint (no MAF on car)?
Many thanks to all who are working on this/ sharing info!

Any 03-04 evo should pass with the 94170015 rom since that was a factory reflash to attempt to remedy a few issues, including the P0300 CEL that they were tripping all over the place. This was reflashed on 03's and 04's and possibly even some '05's but I'm not certain. Aftermarket clutches can still trip this code and it CAN be disabled and still pass MAC inspection, especially since it has nothing to do with emissions.
Not sure if its 100% necessary but I changed the ECU internal ID from 94171715 to the stock 94170015 in case they inspection scanner reads that rom ID code and see's it as a modified ROM ID. This may not be necessary though.
We have already passed MAC with a speed density 94170015 on an '04 evo.
The owner of the vehicle had a full 3" exhaust and speed density intake with cone filter with a stock exhaust manifold and FP Red so they can be lenient on certain modifications as long as the emissions and saftey items are all still legit.
During the MAC inspection, they do look closely into things, especially a catalytic converter. It doesn't matter whether they look at your EVAP and EGR components because the detailed system checks they perform will let them know that it is all actually installed and functioning.
When the vehicle owner first brought his evo for MAC inspection, it was set to Force pass all OBD monitors (the proper monitors were set like factory too) and it still failed with the EGR system and EGR Test disabled so just setting the forced pass items to all pass isn't gonna sneak you past this inspection anymore.
I have removed stock intake manifolds that have utilized their EGR system for over 8 years and the exhaust buildup in the intake manifold wasn't even worth an ounce of concern. Yes, its black colored but its not holding back any power or performance. You will most likely lose about 4-8MPG with the EGR system removed and disabled so if its a daily driver, you really want to keep it.

Wow, this is gold guys, thanks so much for sharing and helping. Brings a tear to my eye. 
Question, was the person with a 3" exhaust using a hf cat? I have a mil.spec 300 cell cat, but I'm thinking I should get a stock one to be safe...

I will have to disagree with what is being said here. I've passed MA inspection with a european ROM without issue. No EGR no CAT. What set the red flag for you is the fact that you passed on tests that should be N/A for our cars. A MAC list is just a list of certified emmisions repair facilities in your area. The root cause of your failed emissions is the fact that to the Registry's computer your car looks to have a faulty ECU. How else could it claim that your smog pump or other such non existent equipment passed its on-board test.

We also just had a customer fail that had his monitors all set to factory with the forced pass settings activated so its not just the 'monitors' that are the issue anymore. They do full tests for all emissions systems and wait for them to run through the test and all pass. It took nearly 20 minutess for all of the tests to run through for the customer that passed.

Jamie I agree and disagree with you. I agree that once you are in the system for MAC then the only way around it is to be 100% in compliance. The trick is to NOT get into the system. In this case I personally feel what threw up the red flag was having EVERYTHING set to pass. Even equipment that the vehicle doesnt have. What has changed in the last month is the registry's pursuit of not only owners such as us but of inspection stations as well. There have been a few stations in my area that were shut down for tampering with the inspection machine in order to pass vehicles that shouldnt have passed. I literally just passed my inspection 10 days ago.

So the first thing everyone is gonna want to do is set the readiness monitors to factory specs like the image below, as well as disable all of the forced pass hacks, which we do not condone. If you fail with these 1's and 0's set properly, you know what you need to do to comply. Im still confused why the people who made the pre-patched V7 roms felt the need to set everyone to 1's and to 'forced pass' anyways.

Jamie my appologies. I just pulled my ROM as I have not messed with the car in a very long time. It is a USDM rom that I passed with. So the euro rom file as well as having passed tests that should be unavailable (ex: smog pump) could be the trigger for these failures. Sorry if I messed anyone up.
