Hi everyone.

I will be titling my 4G swapped Starion for the first time in WA. The car has 280 cams and I suspect it will fail hard.

Do you guys have any suggestions on how to get a car with an aggressive tune through the emissions process?

Tips, tricks, advice would be fantastic!

PM me

Thanks!

 

^a good tune. Have English fix you up if you don't do that yourself. Always pass!

 

Where are you going to register at? If it's Island Co. there is no emission testing here!!! Maybe you know someone in Is. Co.

 

^Snohomish county is the same, and usually cheaper than King.

 

I'm in Snohomish and it's required. The wife and I had to get our daily drivers emissions tested when we applied for WA plates.

Also I do not have a CAT. I can't remember if they did a visual inspection on our daily drivers.

I agree a good tune will help quite a bit, as will high-octane gas. But 280 cams... I mean the thing basically just drools unburned gas out the exhaust pipe at idle

 

Your location says Redmond. That is King. I've never had to do emissions living in Monroe.

What I'm saying is a proper tune will have it set so that emissions will always show pass. You can rumble in there coughing up your own personal cloud of black death but it will still pass. They don't do sniff tests, just a readout.

*edit - Ah, it looks like only parts of Snohomish county are exempt. I guess Monroe is for now?

*edit #2 - Snohomish County zip codes that require emission check:
98011 and 98012
98020 and 98021
98026
98028
98036 and 98037
98041
98043
98046
98072
98077
98082
98087
98201 through 98208
98213
98258
98270 and 98271
98275
98290 and 98291
98296

 

If I am not mistaken, if you spend $150 trying to get it to pass emissions, the test is waived.

 

I work in Redmond but live in Mill Creek. Yeah I'm in one of the zip codes that requires a test.

And I think you're right... it is $150. but the website says you have to take the car to one of the shops in their certified network?

btw, I appreciate the responses and feedback everyone. "The more you know..."

 

If I was stateside I'd help you out as I live in Island County.

 

Does the ol' register the car at a PO Box in that zip code thing still work?

 

High octane fuel will not help with emissions, it has the reverse affect, actually.

The $150 spent to have it waived must be a genuine effort from their list of authorized shops. Most shops will not touch a car of this nature.

Here is what you do:
-retard the timing a bunch at the CAS. Don't forget to mark with a sharpie where it is currently set at. You will probably need to adjust the idle up with the BISS.
-with about a 1/4 tank of 87 octane, add a gallon of denatured alcohol
-install stock injectors
-heat the motor up to 215* or so. The motor runs more efficiently when hot.
-get the AFR set to around 15:1 at idle and 2,500 RPM (I believe this is their cruise speed they want you to be at). The AFR will be affected by the alcohol, so compensate for this. If you go too lean, the car will miss and send the hydrocarbons through the roof. Make sure any sort of hot start fuel enrichment is turned off.

Unfortunately, you will probably be on a set of rollers with the engine loaded up a bit, but this should get you close.

What size injectors?

What are you using to tune? You will pretty much need a way to tune to even begin to think about passing the car.

This is what I learned when trying to get my car through emissions with... "Stan." I tried with 1250s and came close, but the stock injectors made it much easier. I eventually gave up and let... "Stan" take it through.

My motor is built, cat-less, and has 272s.

 

dumb question... is your car awd? if so they cant sniff it... or they dont at least. I just had mine done in lynnwood zip 98037 and i have no cat either. passed easy, and the guy was like "OMG nevr seen under the hood of an evo, can i look?"

 

Not a dumb question, I don't expect people to know a whole lot about such a bastardized car It is AWD. They put the sniffer in the tailpipe. They took a reading at idle and at cruise RPM while in neutral. For OBD-II cars, they utilize the OBD-II port. Easy enough, and easy to fool. Since his car is RWD, he will most likely get the sniffer in the tailpipe and the readings will be taken at idle and on the rollers at cruise RPM.

Different areas may vary, this was my personal experience, I did this several times with the car trying to get it through and eventually dropped the car off to let someone else do the work.

 

Or if you have a "friend" that works too

 

My car is probably more bastardized than your car, with all dsm suspension parts it has lol.
