Hi,

I just got an Evo couple of months ago, and would like to know how much modification can I do and still pass the emissions test. Currently I have RS-R exhuast and looking into either a Flash or Exede. Stage 0,1,2 and up?
Any suggestions will be greatly appreciated.

If this topic had been posted before, I apologize in advance

sup man. i think you can pass smog with the stage 1 from shiv. i heard of some folks doing it. if not the just find a little mom and pops, jose's muffler shop to hook you up.

As long as you have a high quality free flow cat (or stock cat), you shouldn't have any problem passing the sniff test with either an XEDE or XFlash up to Stg 1. Stg 1+ and up (with cams) might make it tough though. Don't know for sure since we haven't tested the higher stages in an emissions lab yet.

Shiv,

I think it would be cool to go ahead and make a "smog" map for all your stages, even the higher ones. Something we can limp to the test site and pass. On the way home pull out the laptop and load the regular maps. I do not doubt for a second that you could do it, even at stage 2, with the expectation that one only loads such a map just prior to testing.

Thanks

Shiv,

Is there any news on this?

The car does me no good if I can't pass emmission in SOCAL. This an important issue.


With a stage 1 can you make a map that will pass emmisions?

Have you tested with a car at an emmision place to see what happens?

With Highflow cat from UR or Vishnu should user be able to pass emmision?

Please test and post results since I know that everone is curious.

Peace,

It's a violation of California law to have Shiv create a map like that and distribute it to his customers.

In short, its against the law to tamper with the settings of the car to pollute less only while testing. Or at least thats how im interpreting it. I'll have to keep digging in the codes to find some specific cites.

But Shiv wouldn't be tampering with the settings to pollute less ONLY while testing. His "intent" is to make an emissions friendly, daily-use map for those that are concerned with the environment. What people do with those maps, or whether they choose to switch to different maps, is entirely up to them.

That being said, I haven't taken a look at the Ca emissions law so I don't know what actually constitutes a violation.

With an Xede it should be easy to have two maps, one low emission map for road use and an off-road map.

Being able to pass emissions depends on the type of test. Sniffer only you should be able to pass even with cams if you adjust cam timing and ignition but if the cat is efficient enough you may not have to.

If it's a running test on a chassis dyno then things may be much more difficult. However, most jurisdictions do not have 4WD chassis dynos for emissions testing which essentially makes 4WD exempt from the running test and sniffer at idle only.

Sad to say I live in an area that uses 4WD chassis dynos for emissions testing.

Interesting fact if true. I guess I should keep my stock cat and exhaust just to be save. We need to test if Stage 1 will pass with a base map. If the car is running leaner and more efficient wouldn't it pass emission with flying colors? I think it will pass but testing is needed for my peace of mind. I am moving to SOCAL and want to know if I should keep the stock parts.

damn california

Stage 1 will pass catted 100%, Snoop!
Its Stage 1+ that *might* have an issue passing, but as far as I knew, you weren't getting cams, so I wouldn't worry about it. You'll pass with ease, as cam gears aren't an issue.

Well, after some digging I found the following:

§ 27156. Air pollution control devices; Gross polluters
(h) This section shall not apply to an alteration, modification, or modifying device, apparatus, or mechanism found by resolution of the State Air Resources Board to do either of the following:

(1) Not to reduce the effectiveness of any required motor vehicle pollution control device.

(2) To result in emissions from any such modified or altered vehicle which are at levels which comply with existing state or federal standards for that model year of the vehicle being modified or converted.

From my interpretation, if you have a "street map" which was suggested by alleggerita, this would be ok since it can be for everyday driving. Just dont call it a "Smog Test Map" and you should be ok. But again, that would require the Xede to be tested by the State Air Board for approved aftermarket part status. So I guess the whole debate comes back to whether or not the larger cams (264's and 272's) pump out to much hydrocarbons for a stock or high flow Cat, and if a tuned down map would actually help. Anyone try the Safe Map that comes with the xede?

I'll call the state and do some asking around for answers later.

On a side note, I think the Red Monster falls into this category..

§ 27153. Exhaust products
No motor vehicle shall be operated in a manner resulting in the escape of excessive smoke, flame, gas, oil, or fuel residue.

All you guys in Cali. read this. I like this idea. here is the link:

http://www.mercurynews.com/mld/mercu...8934718.htm?1c

does the ole trick of driving your car for 15 minutes at ~75mph on a highway prior to getting smog tested still work? I know it used to...

l8r)

That provision is actually in the law itself ex-honda. It states that the government has the authority to do that if they so elect after the pro's and con's have been studied. This isn't something newly proposed by the Governor, but it was basically left up to him to say yes or no.. just took several months to go through the required testing's. I hope it does go through though.. Give me a good reason to get an 05 and tweak it to all hell and back.
