MA Inspection FAIL - refer MAC
A new question...
Does anyone think some of these failures are happening like in my case (Everything showed the way it needs to yet still failed) because of stored history in the inspeciton system??? What i mean is last year the car passed with the stupid Phenom Pass all patch, but this year it sees....wait you don't have these things you did last year.

All good questions. I passed the last couple years no problem on V7, this year no dice. I set everything back to stock and have been trouble shooting the OE systems. Seems nothing on a prepatched V7 ROM can be assumed to be "stock".
Nesiop, sorry to hear you did not pass. Did you check your monitor status after you flashed those changes? Do you have the EGR, EVAP and o2 sensors installed and working?
"Lenient" is not the correct term. The guy at the Braintree stations name is Tony. Great guy, Ford master tech, hot rod builder and racer. He is not out to get you. He will help you get it sorted if your reasonable and then you can go back to the original station to get your sticker. You will need everything intalled and working. They (MAC) won't car about an Ebrake, but I would think you will need that at some point like the original inspection station?

Yeah, in the future I plan on using a linelock setup, but yes, My Stock IM is back on, EGR functions (logged EGR Duty Cycle) EVAP is connected, o2, FPS, etc. All monitors jumped to ready after a couple miles except the EGR and EVAP. I tried what I could to run the drive cycle but without being on a dyno it is VERY VERY hard as it is driving the car up to 38mph for like 90 seconds, decelerate to 18 mph and hold for 20 seconds, in which you CAN NOT use the brake to slow down or turn the wheel, bring it back up to 38 for another 60 seconds, slow down park, idle. Something along those lines.
So when I got the info to patch those two I popped it on and failed. I scanned, as did the shop prior to the inspection machine and all passed that were needed, just like you have above:
Cat____________ready
cat heater_______NS
evap ___________ready
2nd air system ___NS
AC system _______NS
o2______________ready
o2 heater________ready
EGR_____________ready
All those were ready except the EGR and EVAP PRior to those changes, and then after the changes those were ready.

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.

Can you explain to me how the EGR removal results in 4-8 MPG loss?
Good luck to all my MA guys. I used to live in Boston. Now I deal with CA emissions!
Thanks
Be careful guys, these "fixes" being mentioned are not real fixes and no matter how you did these changes over the past few years are whats getting people flagged. I was told by the MAC guy that the car was flagged because in 2010 my car did not read as an obd II it was a euro rom (Tephra patch was Euro), in 2011 it showed up as a obdII but with everything passing which is physically impossible he said (Phenom force all patch which made the AC and secondary air) and then said in 2011 it now shows that my car doesn't match last years results meaning bits were changed in the computer. So basically putting everything back, getting it to pass with everything meeting the drive cycle still would have flagged my car because of the prior years.

These are the factory settings for a 94170015 ROM. If you get a CEL, you will need to fix the issue prior to attempting to go to the MAC station. You can disable the notoriously bad P0300 periphery bits though.
Again, I am not condoning any illegal activity here. I am merely showing you how to put it back to stock settings so everything is fully functional.

Sorry about the old thread bump but I just had to deal with this today. My car passed all tests when I went to get a sticker but still spit out a rejection sticker much to the mechanic's surprise. Anyways I scheduled an appointment today to get it checked out at the MAC in Braintree. Tony the owner seemed like a real nice guy and is big into drag racing. He mentioned that my exhaust was a bit on the loud side (full turbo back, resonated test pipe + cams) but aside from that it was nice and painless. He cleared the flag and I just got a shiny new inspection sticker.
Moral of the story? Go to Braintree as long as you have your ECU in order haha. The whole process took probably less than 10 minutes.

Pulled a dumb moment and forgot to flash my ecu back to the inspection flash I normally use and went to my inspection station...
Second trip back to the MAC.. go figure...
I normally try the Medford one but looks like the Braintree one seems legit. Is there only 1 guy at that place? The one in Medford I believe has multiple guys running it.

According to the lady on the phone I'm the first person to be back two years in a row.... I should get a medal.
Got the EGR system back in, I think the EGR is junk like my first one. Car sounds like it has 280 cams but I haven't been able to work on it with the two jobs. Luckily I have at least 1 reliable car...
Fun times..
