Megasquirt and GA emissions
I'm considering a slow entry into boosted life and figure the best place to start is with the ECU. I'm in GA and the county I live in has yearly emissions where they scan the OBDII port. For those running MS and living in a emissions state, how do you resolve this ?
Thanks in advance.

I have to go through a half-day "de-tune" (stock ECU, stock injectors, pull the exhintake cam, remove adjustable cam gears, wire open the turbo), and then 2-3 days of getting the readiness monitors to go green and/or resolve any codes that pop up. Then there's another half-day of "reversion" back to being boosted.
It's painful, but necessary.

I have 650cc injectors, and the stock ECU won't be able to deal with them either, so out they go.
With exhintake cam in, the car will run, but you'll throw a code, I don't remember if it's the P0300 or P0420 code . Either way, the readiness monitors will never go green. So that has to come out.
In other words, you've got to get the car close enough to stock to get the ECU to behave itself and let you pass.
PS, I forgot about reinstalling the narrow band O2 sensors, both of them. I tried just leaving them in, but running them "cold" for 11 months significantly reduces their lifespan. Better to take them out and plug the bungs than to have to replace them every 2 years.
I just count all of this as my "turbo penance" for having so much fun the rest of the year.

Also depends on your setup greatly. Lar's kit is very easy with all vband exhaust. I also have a MKTurbo kit, while I haven't reverted mine to stock, 2 hours seems totally reasonable just guessing on what it would take for mine. Having those nice little details makes the world of difference.

The stock ECU can't deal with boost so you have to wire open the WG.

I looked into the requirements for it and it really isn't hard to get certified. You have to have a valid ID, take a 2 day course, and pass a test scoring 80 percent or higher. I am not familiar with their actual test procedure and what they may or may not send back to the state regarding your vehicle and test results.
If any data such as actual emission results or an OBD print out is required to be sent back then I wouldn't really be able to help. If it just requires a "test" and you could say that "test" was performed with some forms then why not just get certified yourself and hook up all the other tuner people you know.

Requires equipment that went through a fairly large update 2 years ago (subsequently, a lot of OBDI emissions places shut down - only 2 years left on the OBDI stuff anyway, no point in investing) - a lot of Gen 1 OBDII stuff had issues with the upgrade, dunno if those got sorted out or not. Results are electronically transmitted to the county. They also ran a few stings - a few places got salted and wiped from the face of the earth.
Should also mention in GA - 96-00 can pass with 2 readiness not set, 01+ requires all but 1.
