Megasquirt and Emissions Testing
Hi All,
First, I am super new to this site, to tuning my car, to Miatas, all of it. I got the car kind of as a project during the quarantine, and I am wanting to re-work it a bit and have bought a bunch of parts to do so. One challenge I have is that I have never registered the car (as in got a valid license plate), so I need to do that. I will need to be able to pass emissions testing, but I also want to run a megasquirt tuning thing (whatever the heck you call them) and am upgrading my turbo, exhaust, etc. So, the question I have is, if I need to run the megasquirt, hoew can I pass emissions testing? I know they won't be ab;e to plug into the port under the dash, so I don't know how it works. I am just now getting started on the project, and am trying to do some research before I get too far down the road with everything. Thanks. https://cimg2.ibsrv.net/gimg/www.mia...a45e4dae59.jpg The car prior to any mods. https://cimg5.ibsrv.net/gimg/www.mia...74229bb858.jpg original engine bay https://cimg8.ibsrv.net/gimg/www.mia...923b2f8312.jpg |
Either find a way to register and plate it in a non-inspection state or swap back to stock for every time you need one is what i understand.
Megasquirt is not emissions compliant. Not sure if its true or anecdote, but i heard certain costal states can crush your car outright or give unaffordable penalties if you get caught. |
What state are you in?
CA emissions testing for your car will fail you for anything aside from a stock ECU. Your '05 is tested on an OBDII scanner which the Megasquirt won't communicate with. Most people set their car back to stock (and drive it that way for a couple hundred miles to set the smog "monitors" required so the ECU will pass the smog machine's OBDII test) every two years here before smog to pass inspection. Then revert back to Megasquirt/turbo/etc following the smog check. When I was still in automotive school, a couple of my classmates "had a guy" for their cars but I'm not familiar with how that works.

Moral of the story, keep all your OEM parts and emissions equipment somewhere and try not to get pulled over in California! :rofl: |
