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.

So the first thing everyone is gonna want to do is set the readiness monitors to factory specs like the image below. 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 anyway.

People keep PM'ing me saying we shouldn't be in this thread because we are a business.
Let me make this clear:
WE ARE NOT CONDONING ANY ILLEGAL EMISSIONS TAMPERING WHAT-SO-EVER!
We are just helping members that may have downloaded pre-patched rom files that were preset with incorrect settings for the emissions systems to function properly. If anything, this shows that we, as a company, are trying to RIGHT these wrongs so every Evo is adhering to federal laws.
Let this be documented right now.
Thanks

I would ask him why he's checking fuel trims? Fuel trims are a +/- percentage and are never the same, even on a stock car. Where's it in the law book he can fail you on fuel trims?
What is he saying about your idle, that it's to rough?

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.

5th time? WTF does he want you to do at this point? Why is he giving you such a hard time?
I would ask him why he's checking fuel trims? Fuel trims are a +/- percentage and are never the same, even on a stock car. Where's it in the law book he can fail you on fuel trims?
