It takes a few hours max. I also swap my exhaust to add a cat. It was much easier when i had a 94-97 intake manifold because its quicker to change out injectors. The biggest issues I have had are mostly non turbo related:
Blocked EGR Causing readiness not to pass (back when I left my block off plate on)
Clogged EGR causing readiness not to pass (removed and cleaned it)
faulty o2 sensors and o2 sensor wiring
BOV leak causing VERY LEAN running conditions because the leak was after the MAF
Get a good OBD scanner that can read readiness codes AND sensor readings like o2.

THIS. Oh and if readiness doesn't pass in a few heat cycles and driving conditions then you probably have an issue. Nothing clears before EGR...so clean and check that FIRST. Ask me how I know....

we have to pass visual for stock smog equipment, tail pipe test, CEL needs to be off and OBD2 will be hooked to the smog machine to verify readiness. Its utah and we have to test every year.
I found the OBD2 test procedures from the gov website but it seems to simple. It seems to suggest my wont need a tail pipe test which may or may not be true.

While the general consensus opinion here at MT is that MegaSquirt 3 > * (and I have personally owned several Megasquirts including an MS3Pro), I must admit that the apparent simplicity of leaving the stock ECU in place to manage the things which it's good at, and adding an external signal modifier to adjust fuel and ignition timing as appropriate, does have some appeal to me. I just wish that there were a better implementation of it available today.
It sucks less than pouring radiator stop-leak into your oil pan, if that's what you mean.
I've never actually used one, nor heard direct feedback from anyone who has. The dyno charts which Bell show on their website certainly seem reasonable for the configurations described, and impact on out-of-boost performance should be extremely minor.

Inside joke.
A few years ago, there was some guy on here who thought he had a leaking head gasket. He went to the auto parts store and bought a bottle of some miracle product which claims to fix such things. Despite the fact that the label on the product said to pour it into the radiator, he poured it into the oil.
As the product contained a large amount of suspended particulate matter designed to dissolve in water, it blocked the oil pickup screen and resulted in the nearly immediate destruction of the engine.
Unaware of the fact that he had ignored the instructions on the label, he started a thread here to the effect of "Beware, this product destroyed my engine," whereupon we all proceeded to point out the fact that he's misused the product and was responsible for his own engine failure.
It was funnier if you read the whole thread. I can't find a link anymore.

I actually got a PM from Mouglie just a couple days ago asking me about turning up his boost
....To add to the Emanage/Xede post - keep in mind that while its cool for that 1 day every 2 years, you are then left with two systems which are trying to trick each other or fight each other all the time, and you are also left with a bunch of junk that you have to work around (egr, solenoids, sensors, all of which throw a code as soon as you exceed a threshold), and a bunch of limitations (the maf getting maxed out, injector size limitations, etc). Its really not all as peachy as the bandaids users will have you believe, and definitely not as great as some companies will fool you into thinking.
Megasquirt isn't all peachy either. There is a steep learning curve, there are a ton of different versions and a ton of conflicting documentation, and it takes quite a bit of time to set it up to run just as smooth as OEM. Once you "get it" though, it's not even a comparison with AIDZ.

I hate those chemicals it seems they have one for every mechanical problem. they should be boycotted and parts stores that sell them too any part store that sells them should not have business and not be taken seriously. I am suprised they dont have one for broken rods or cracked block. people who use that stuff are those who buy those miracle fuel magnets hoping to get 100mpg. pouring it in the oil and not reading the intructions is hilarious and sad.
Wut.

Basically the same functionality as the XEDE, but trimming the outputs rather than the inputs. When you tweak the MAF signal, you're changing more than just fuel duration.
Sounds like a business opportunity.
In general, we Miata folk tend to lean more towards the cheapskate / DIY end of the automotive aftermarket, and DIYAutoTune was quick to embrace the platform years ago with the Megasquirt ECUs. That's just how things settled out...
But at the end of the day, it's really down to what Concealer and 18 have said. Engine tuning is hard, and there's really no single ECU product which is significantly better-performing or easier to use than the rest. It's mostly a matter of what ECU happens to be recommended by whatever vendor you're dealing with for related parts, what ECU is most popular with your local enthusiast community (and thus supported by a knowledgebase), and so on.
