Emissions
How do you guys pass emissions with aftermarket engine management on obd2 vehicles. Me and my brothers are working on a project car (1999 miata) and cant decide what engine management to use because going back to stock(will be a forced induction car so will require more than just swapping the ecu back) just to pass emissions is sort of a pain in the rear. We wanna use megasquirt but ive heard of a few people running a dsm ecu with dsmlink and if we can do that and still be able to pass readiness monitors that would be cool.

lets see, the car will be running 750cc injectors, egr delete, maf delete for speed density, and all other supporting mods, so if you are referring to plugging the stock ecu back in then that wont work because for one the car wont even run, for two if it even did it will trigger a whole bunch of cels which wont pass emissions. But thanks for the input mr. guru.

You mentioned nothing of big injectors or anything else.
What you DID ask was specifically about the ecu swap, and I answered YOUR STUPID QUESTION SPECIFICALLY. As in, if you unplug the oem ecu, plug in a pnp ms and tune it, and many actually do just that, the whole ordeal of "swapping back to stock for emissions" takes all of 5 minutes to reverse. I have personally done that actually.
And I'm not even TOUCHING on the fact that you are ridiculously lazy and can search this topic and get many hits with clear answers, but you are too much of a self entitled dipsh!t n00b and think that everyone is mandated to spoon feed you or else.
You're welcome, fgt.

Next time you ask a stupid question or make a vague lazy post, consider what you're asking and what your post states.

whoa there calm down, no reason for that attitude it wasn't a stupid question considering that this is the miataturbo forum maybe you are intelligent enough to piece together that it would be far from stock. So much attitude behind this wall of internet, why don't you come and talk to me face to face and we will see who the self entitled dipsh i t is. To the rest of you sane people, sorry this is going to be a boosted miata with aftermarket injectors, walbro 255lph, thinking of using an hx30 turbo but currently have an evo9 turbo, custom exhaust manifold and the rest of the exhaust, flying miata clutch, and more supporting mods. The goal is to have a vehicle that can pass washington state emmisions with the least amount of hassle. So how are you guys passing emissions with your turbo miata?

By either not living in a shitty state that enforces emissions..... OR.... by not being lazy, and keeping all stock parts to spend 3 hours or so swapping back to pass the test, then another 3 or so reversing it that night.... Basically, you take 1 day off work, one that coincides with your scheduled appt for emissions testing. Either the night before, or the morning of, switch it all back to stock... Do the test, pass the test.... drive home, swap it all back to glory.... 1 day sacrificed out of 365 isnt much to ask in order to have a properly boosted and tuned miata... just my $0.2

Whats so funny? you don't know who i am and i bet you wouldn't give me that attitude if you spoke to me in person. Don't you have something better to do other than flagging negative props on every one of my posts? And me trying to pass emissions on an aftermarket ecu is no worse then you going back to stock and passing.

All right, you guys- rinse the sand out of your vaginas. Vlad, I'm looking at you, sweetie.
There is not, so far as I am aware, anything like ROMRaider or DSMLink for the Miata platform. Consequently, setting up forced induction to pass OBD-II emissions on these cars does take a bit more work.
One popular approach is what's known as a parallel install, wherein the stock ECU remains in place and continues to drive ancillary functions such as idle, aircon, etc., while a secondary ECU such as a Megasquirt is connected to the injectors and ignition coils. This is somewhat similar to the old piggyback-style engine management systems (emanage, Xede, etc), except that neither ECU is acting as a signal modifier for the other, they're merely doing separate tasks.
Obviously this requires that you leave most of the stock hardware (EGR, MAF, Evap, etc) in place, though it's not like these things are robbing you of power.

Which sucks.
This is by no means an easy install, and you have to really get the tune right to keep the stock ECU from throwing fuel trim codes, but it can be done. There was a time, in fact, when this was the standard method of doing MS installation on the NB; before things like alternator control and VVT were well-understood. I would imagine that the documentation is all still lying around here somewhere...

Unless you tell people where you live no one knows what your emissions requirements are. Go to google and type in your state's name and "emissions testing" and then figure out wtf you have to do. After you do that search this forum for emissions testing and read all the info that's already here.
