I passed emissions!!!
 

With no cat a megasquirt and 450s :D

Autotune FTMFW.

Bad ass.

Maybe I try to pass next year.

How in the hell does one pass emissions w/o a cat? I thought that was autofail.

GJ though.

Me too...which is why I don't even go try.

Well...that and my non-existent horn.

Washington state doesn't have a visual. Only a sniffer at idle and 25mph.;)

Horn = emissions related where you live? That's sad I just have the sniffer test.

OP congrats, I once got a (mazda) car to pass that was tested as an egr equipped 1.6 but really had a no egr 1.8, turbo, race cat, 360cc, no emissions equipment (charcoal etc) and a jdm factory ecu (read nowhere near emissions friendly). So I know how good it must feel.

Weird. I just thought you'd have to have a cat to pass the sniffer.

I've heard that in lots of places, emissions double as a safety check as well.

This, inspection is a safety check and emissions rolled into one for the major metropolitan areas here. I'm about 5 miles from being in a non-smog county, where state inspection still costs $12.50 (<~52 or whatever).

A couple of my friends who own Hondas passed last year on stock equipment and no cat, so I knew it was possible. I just figured I'd give it a shot because had I failed, the second test was free anyway, and I would have just thrown on a cat.

Test Results
-------------------
HC (PPM)
Cruise Limit: 180
Cruise Emissions:114
Idle Limit: 220
Idle Emissions: 198 <--too close

CO (%)
Cruise Limit: 1.3
Cruise Emissions: .45
Idle Limit: 1.2
Idle Emissions: .28

Edit: $50 bucks!?! are you kidding me? Its 15 dollars here.

Hell, $50 is cheap, that's when you're legal and can pass it.

Good job. Glad to know its possible but also glad I dont have to worry about it in bellingham.

I actually knew a guy that went and did it with now exhaust. They just put the sniffer in the end of his header and he passed in his crx.

It was a good feeling when I passed too. In Oregon it's free until you pass, and then it's $21. I still think we should make a MS emissions friendly settings thread. I think the timing and tuning for 15.3ish afr is what helped me. I was surprised how hard it was to maintain 14.7 exactly at idle, as well as how much engine temperature affects idle rpm, putting it in a different part of the fuel map.

lol tell em its hydrogen hybrid car that doesnt need a cat. Its proven that by adding hydrogen to the combustion chamber, everything burns complete therefore almost no unburned gasses out the tail pipe, you can add a bit more fuel to lower NOx. Oh wait that wont work the gov is too stupid to keep their testing facilities up to date. Currently they have electric cars failing because they have no tail pipe. My fav is the prius and honda hybrid failing since the motor is designed to turn off if its not used and the electric motor can supply the power.

My car is registered in MN, no emissions testing.

Good job on passing though. My car would fail immediately because it is a 97' and soon to have a MS, OBD-II FTL.

TX has higher inspection fees than most (all?) other places I've lived, but WA has a higher state gasoline tax. The states will get their money out of you and your car, one way or the other. Especially WA where you get a lot of car-hating hippies elected to public office. Any of you guys have to pay that fucking monorail surtax they had in Seattle ~5 years ago? :vash:

I agree, and one of you guys who has already passed smog with MS should start it. As often as this comes up it should probably be under the "Super Important Megasquirt Threads" IMO. Describe the conditions of the test (idle and/or whatever speed they have you on the rollers, how many rpm if you remember), post the target AFR and ignition timing you used, and your results compared to the allowable limits. I have a pretty good idea of what settings will work (AFR 14.7-15.0 and conservative timing) but if we get 5 or 6 guys to post their results that should be enough to establish a range of settings that are confirmed to pass.

I put catalysts in my test pipe. That's why you passed. Now I hope you return the favor tomorrow. Lol.

I have to get some emissions friendly settings and get my idle under control. It idles anywhere from 1800-3000rpm and won't go down. Bouncing off the rev limiter at 900rpm, with no throttle application, probably won't work for the test.

Oh and testing is $38 first try $18 second try then the cycle resets and your back at $38, it gets pricey fast if you don't know whats wrong.

Dear lord, that's a really high idle. Check for massive intake leaks in the intake manifold, and if your throttle cable is bound up. There's a rubber plug blocking a big vacuum port on the back of the intake manifold, you must have a massive leak.

Turn off your ISC and try setting the idle manually. If you cant get it under control, you have a vac leak somewhere. If it drops down to something manageable and holds, either your IAC is toast or your settings are really messed up in MS.
