please tell me, or point me to a link to find all the secrets to passing emissions tests. Don't hold anything back. I want to learn some more. Thank you,

ODB

 

Hell, I don't even know the secrets.

Smog is weird, I've seen some real beaters come in and they pass no problem. On the other hand, some really good running cars won't pass.

I learn something new every time I smog a car, its tough.

Are you having a problem passing??

Nope I'm not having a problem just wanted to add to my big collection of cheater tactics. That's all.

 

i think if engineboy knew he'd be a rich man and he wouldn't be posting them for everyone to read for free. i'm glad i live in the middle of no where, we don't have e check.

I wish I could find a bunch of stuff about smogs. It would help me every day.

I have some "cause and effect" type stuff around here but its been more of a "hands on" learning thing for me.

I personally think the program sucks, but I do what I'm paid to do.

Let me know if you have any questions, I don't know the laws and limits in Illinois, but I'll do my best to help you out if you need it.

Lots of isopropyl alcohol and lots of it. Nothing runs cleaner than having alot of that **** in there during the test. Not to mention it does a good job of snatching the moisture in the tank and burning it. When I lived I maryland emissions came and forced the sale of my baby. My 87 355 s10 that ran 11's all day long. There was a grandfather clause at first and if you could document that the engine came from something presmog they would issue you a waiver. I was lazy and never did it and they only offered it for the first year. Oh well, now the rule there is that the engine must be same year or newer and can not be a different displacement thatn what was available in that model. Viva Texas now baby. My newest s10 v8 has a shield I pryed off a factory cat wrapped around the front section of the exhaust. Passes texas inspection every year. Now when they hook a sniffer to the pipe Ill be putting lots of rubbing alcohaol in the tank.

I got BAD news for everybody that is not subject to emission testing. Canada and the US are in talks about implementing California type emissions throughout North America. I work for the Provincial Government of BC and have read various "proposal papers" about it.

As part of this implementation program, Canada (under pressure for the US) will be getting Federal (currently it is Provincial) guidelines as will the US (it was the US' idea). The US is after Canada to broaden its enforcement of emission testing as only a few areas have emission testing in Canada (the Lower Mainland of BC as well the Greater Toronto, or it Toronto will be). So part of the deal will be California type testing everywhere.

Also they are looking at plans to test diesel engines on large trucks which tend to be exempt everywhere.

Lastly, they are looking at "clunker" laws where, they don't care what the emission standard of your car was at the time; if it wants to retain it's regular plate status, it will have to meet the standard or it will not pass. An old carb'd vehicle from the 60's produces as much emissions in a day as a newer car in a year according to the study. The only exception will be "collector cars" which will have limited plates covering special effects and weekends.

The Province of BC is a large advocate of this program and currently have lowered their emissions levels for a lot of older vehicels. When I lived in the Lower Mainland, the Government lower my emission standards from California's levels to less than half of California's.

They also want to address Sulphur emissions and want to look at testing that. But the oil companies are currently lobbying against it as the crude oil used is a major factor in sulphur emmisions. Rumor has it that to guarantee the quality of gasoline for sulphur emmission, the price of gas would dramatically increase.

I wouldn't be to quick to remove my emissions equipment today. This is one of the reasons I am retaining my entire emission controls on my car even though I currently live in an area where a car can pollute good like a car should. It will be coming and a lot sooner than people think.

 

A chapter in the apocalypse for all (most) of us..... They will have to pry my dead body out of my car if they want it!

 

or just keep a stocker engine and play musical engines at inspection time.



yep yep, methanol baby..
methanol works way better than rubbing alcohol.

 

ODB, I am JUST leaving to go out of town, and I wanted to let you know that I responded to your question about a "limited" operation ecm. Yes, I am actually looking into it. I think it would be a "hoot" to make a TPI/TBI car run with a carb and/or a non-ccc distributor and have only those functions you wanted to remain.

This would solve the problem that people have going to a carb and dumping the ecm and loosing their computer controlled TCC. I would suggest that it also opens up the possiblity of retaining the computer controlled distributor as you have so much more you can control with it. But you could have the option of keeping it or dumping it.

I will say, that when I got my car back in 1991 and I found out (at that time) "how little you could do" to modify the TPI, that I seriously looked into dumping it and going carb (there is so much more top end potential with a carb IMO). But I was living in the Lower Mainland of BC at that time and they JUST instituted emission testing "California Style"; so that deep-sixed my plans to convert to carb.

And when I moved to Kamloops I began to reconsider it again, until I found that "discussion paper". It's nice when you work for Government and can see some of the "publi info" that noboby looks at until its too late.

That is when I concluded that EFI was here to stay and to learn to "work with it" instead of dumping it. But I am well ahead of you and YES I can see it being totally possible to burn a "special eprom" to only use the features you want AND not throw an SES light.

My other "commitments" in life preclude me from offering a "special eprom" tomorrow. But I will definitely keep this in the back of my mind and possibly have a "solution" in the summer. But it would require testing and feedback from someone.

Time and commitments requires me to be selective in the "projects" I undertake. But I was already considering this one on my own. I just need a "tester" that would be interested in running the "special eprom" as my car is not setup for this. All the "programming, emulation, theories and books in the world" is no replacement for actual real world testing.

Do you know anyone that might be interested in such an idea?

Wouldnt it be easy to just use the comp setup from a monte ss or lg4 camaro?

 

ODB, some cheats for emissions? I think I can come up with a few...

1. Idle speed. The books say stock idle, however, you can typically go up to around 300 RPM over stock without trouble from the emissions tester. This will help CO and HC.

2. Some states check ignition timing, and typically the +/- variance is 3º. If you can, retarding the timing can lower CO and HC.

3. Warmer engines run cleaner.

4. If you have really high HC but your CO is 'pissa' then swap out to a colder plug, and vice versa.

5. Air injection really works.

I have a a few things in a list for what to check when your over 'X', the above are 'tricks' gleaned from that nice little list. Hope this is partially what you wanted.

 

Glenn, I have no fear of across the board emissions standards in the US anytime soon. The Bush whitehouse ran on smaller govt., and if anything ever came close, it would die in Congress. Could you imagine the outcry the states would make in incurring the costs of such testing? I doubt any state wants an immediate black market on stickers. That said, I personally wouldn't mind, if you can run it claen do it. You can make good power with emissions as well as without.

 

Red Devil: All great advice.

The idle suggestion is one of the best ideas...In CA they will usually give you 1050 RPM on most cars if the person doing the test will let the machine go that long. (Thats the hard part)

Emissions laws won't change that drastically anytime soon!! Too many reasons why!! B'sides, there will always be a way around them just like there is now!! I do feel sorry for the people now tho' that live in states with strict emissions laws like California!! Here in Missouri the whole inspection process takes an entire 10 minutes...if that!! You pull up the car, shut it off....they check lights, blinkers, wipers, and horns....then fill out the paper work!! VERY FEW will even bother looking under the hood or underneath the car!! Oh, here's a better one......in Iowa there are ZERO emissions laws!! The vehicles are inspected when the car is NEW....after that the tags are renewed every year and that's it! Even if you buy a car off an individual it doesn't have to be inspected!!

thanks red devil
thanks glenn,

if you find a way to frankenstein a stock ECM, it could replace several performance electronic parts at one wack.
I have a whole list of crazy uses for it that all would help me to go faster.

I think after all the years of stress the ECM caused me that it's time for some payback.

I have tons of test equipment, the car to do it on, and a never ending will. I volunteer.

I actually need an electronic controller to match one of my future performance products. If this idea works then it could be all I need. Maybe we share in a partnership or work a deal for the rights to the technology.

 

Any car can be made to pass clean on the sniffer test. You guys talk about strict California laws but they're not that bad at all. Your parts will be a little bit more expensive as all smog-exempt parts are, and you cant switch from EFI to carb (why would you want to?), but its definitely possible to pass CA smog and have a quick car. My car is 99% smog legal and daily driven. I say 99% because not everything on my car has a sticker. But its close enough.

Glenn, I cant believe you've ever thought about switching to a carb. You've been one of the best TPI guys around here for a long while.
