I have been warning most of this year that all states would switch over to the new EPA OBD-II I/M tests,
and that now has become law as of last June.

All 50 states must comply and states are now beginning to inforce the new smog tests for they are cheaper to due by the smog stations, need only a PCM scanner, and have the PCM report if you meet or fail smog tests.

Again think if you really want to spend $400-500 for some tuner to overwrite your PCM code and now you not only can be rejected at smog testing but also fined $2,500 as per federal law on modifiying EPA defined PCM code.

I caution you have a EPA compliant PCM scanner and run the I/M tests before going for smog tests to assure you would pass before being tested.

In part, as Ca has published:

STATE OF CALIFORNIA - STATE AND CONSUMER SERVICES AGENCY GRAY DAVIS, Governor

BUREAU OF AUTOMOTIVE REPAIR

10240 SYSTEMS PARKWAY, SACRAMENTO, CA 95827

Official Notice

December 21, 2001

To: All Licensed Smog Check Technicians and Smog Check Station Operators

Subject: Inspection of OBDII Systems

Federal regulations (Title 40, Code of Federal Regulations, §51.357) require that the Smog

Check program include OBDII functional testing as of January 1, 2002. Attached you will find
the BAR-97 EIS OBDII test procedures; insert the procedures along with this notice into your

Smog Check Inspection Manual (Part III) between pages 90 and 91. Licensed technicians must
follow these procedures when performing the Smog Check inspection on enhanced area vehicles.

As you may know, the OBDII test requires a BAR-97 software and hardware update. The update
must be installed on all BAR-97 EIS units operating in enhanced Smog Check areas and on any

dynamometer equipped BAR-97 EIS units operating in basic areas. Upon determination by BAR
that enforcement action is appropriate, BAR will commence actions against stations that are not

compliant with the update requirement. To avoid any disruption of inspection capability, stations
should strongly consider the immediate purchase and installation of the update. Please contact

your EIS manufacturer for information about the availability and installation of the update.

Once the update is installed, the automated OBDII test must be performed on all applicable 1996
and newer vehicles registered in enhanced smog check areas.
For basic area stations using a BAR-90 analyzer or BAR-97 platform (without a dynamometer), there will be no change in the current inspection procedure.

The OBD II test is an automated process that interfaces with the on-board systems to evaluate
and report the status and/or results of the readiness indicators, system faults and malfunction indicator light (MIL). Be aware that the traditional MIL functional check remains unchanged.

During this initial phase of automated OBDII testing, vehicles will not be subject to emission
control monitor readiness requirements. The test data collected during this first phase of testing
will provide BAR with the information needed to establish appropriate readiness requirements
and retest procedures.

The BAR-97 update contains additional upgrades, including the following:

• Remote Software Update Capability: Allows future software updates to be installed by
the user or on-line by the manufacturer; a service call should not be needed.

• Improved Fuel Cap Test: Allows technicians to replace defective fuel caps during the
Smog Check inspection.

As usual

Cali leads the pack.......guns, trees, air, water, whatever will get THEM into your life..........what ever it takes they do it...........

Thanks Team, I have figured this was coming..........THIS is the major reason I have been & will continue to look for ways to improve HP & performance.........but not at the risk of dealing with the federales........fines, I DO NOT need.......

You guy's that are/have deleted your cats...........get ready..........and my .02's, says if you are thinking about it, better re-think................:eek:

There are other ways to skin cats..................( no pun intended):lol:

Re: As usual

Ca is the leader of sticking it to the taxpayers but in this case 13 other states have been testing the I/M tests for over a year now.
Some states/counties were not doing smog like others because they were waiting for cheaper smog testing and now that the PCM itself has I/M tests running as a norm, smog stations can now use those tests by just plugging a scanner in and everything is handed to them on a platter.
I've been stressing that people own a decent scanner so they can always know if their car would pass I/M tests or not.
With a scanner you know in less then a minute if car passes, fails or is rejected.

CT IM 240 testing

Hi there,
As for the IM 240 testing issues, this has been running in Ct for about 1.5 years. Very rare at first, on using a dyno when you fail the first test. They used the dyno to check another form of the test, would help you pass. However, using the dyno has been here full force for about a half a year.
After the initial shock, you will find, that as long as you have your cats, for the most part, you will do fine.
Just be cautious, as the OBD issues self tests, alot of places will not even notice, as the calibrations are changing, you will find that sometimes, the scanners, they dont even know what they are looking at.
Simple solutions, do not guess. Talk with your c5 specialist, as they will advise you accordingly as to the mods that will help you increase power, without harming your emission test passing capability.
In CT, you must be licensed to perform repairs for emissions failures in the state.
If you are appropriately advised, you will be fine, and have power too.

Hey Terry,

From my understanding Collin Co will be directly affected by this come May '02. Not only will there be an idle sniffer test (like Harris, Dallas, Tarrant and whatever country El Paso is in), but there will be this hook-up into the diagnostic port on all OBD-II cars. I'm not sure exactly what they're going to do to OBD-I cars...that doesn't affect anyone with a Z06, of course.

So does this put all tuners out of business who have pcm changes made on cars or does this jut mean the car have to pass emissions?

I had my pcm modified by Steve Cole of TTS and the car easily passed the NJ emissions standards which are about as tough as you can get. They spend a tremendous amount of time with mirrors under the car though...looking for cats?

Although I passed..easily..the dyno experience with some yuk in my car(with no chucks on the front tire-too low)...was enough that two years from now..when I need to repeat this..I"ll spend the 50 dollars and go private and local..

All I can say is...


Lots of good people make their living modifying cars with heads and cam..superchargers etc and they all usually rewrite a portion of the programs..for one reason or another....


Come to think of it though..doesn't GM update the programs from time to time on Chevy dealer service calls......Wouldn't that be a pcm violation as since they altered the program?

From your post John, it sounds as if anyone who touches the program would be in violation..would that include GM dealers as they perform updates?

I look foward to your response.

Thanks.

Thanks for keeping us up to date with the latest bad ideas from California, John ;)

I am unsure about the 50 state requirement..

In Michigan, Wayne Country (aka DETROIT) had emissions testing in the early to mid 90's (idle sniff test). Because air quality improved, it was completely eliminated.

Generally, states are coerced to do these programs by the witholding of "federal" highway matching funds (which already came from the state's taxpayers).

It was my impression that as long as Michigan air quality remained good, there would be no testing, especially IM-240.

Other counties in rural Michigan have very low pollution. It seems goofy to have folks in areas where the population density is extremely low get tested. But California is all about goofy laws.

John, any idea how the 50 state requirement applies to older cars? What are the cutoffs?

Wes, JB

Wes, what do you mean doesn't affect Z's????/.....tounge in cheek/....
Also, what is the diff, in OBD 1, and OBD 2???.

JB, it is my understanding that PART of the program is EPA mandated, and THIS particular part CANNOT be altered..........or you will be in violation, of EPA guidelines........and now since all EPA agents pack heat.....if you have changed the PCM(EPA part) you will be shot summarily at sunrise:lol: :lol: :lol: :lol:

OBD stands for On-Board Diagnostics (you probably knew this). The OBD-2 requirements are much more stringent than OBD-1. All '96+ model cars have OBD-2 compliant systems (PCMs, emissions, etc). So, anything pre-96 will not be subjected to the PCM diagnostic test, but there is still plenty of tests for those cars...just doesn't affect a new Z.

I don't know _exactly_ what has changed with regards to OBD-1 vs. OBD-2. However, I do know there is a lot more datalogging capabilities in these new PCMs compared to the one in my '90 Mustang and in my old '94 Lightning. IOW, big brother is watching...both when you go get an emissions test and when you take the vehicle in for warranty work. :puke:

OBD-I was the 1st generation and since computers were not in many cars and those that had computers were slow cpus and its purpose was for alarming if something was failing.
EPA took over what was then called a ECM, making it into a PCM, and changing its purpose to test and monitor for smog, thus OBD-II came about with a shitload of smog functions/tests.

Yes part of the PCM is mandated by EPA but also parts related to meeting CAFE and SAE rules may prevent changes.

But a so called PCM tuner would also be violating federal laws for 1 G.M owns the code, its copyrighted.
2, EPA clearly says PCM is part of smog functions and cannot be modified without being tested and approved.

Thus if the product has no CARB license, its a clue you can get fined by $2500 for using it on a licensed car on public roads.

A vendor making a off road only statement in fine print, helps them some, but they still would have to prove they did not steal G.M's code and modified it, but either way if seen in your car on a smog test, your lible for the fine and car is rejected and no license plate tags will be issued.

As to just changing other parts of the code, if in fact it causes the PCM flash to be replaced, that means the code would have a different Ca ID, CRC, etc and that is also illegal since EPA says PCM must have a valid version of flash that G.M produced for that model year.

So all these tuners like LPE and Mallet and the list is long are all out of business?

Something doesn't sound right about what your saying John..

All these tuners who do heads and cam..superchargers ..turbochargers..etc that would just modify a pcm ..POOF are out of business?

All the guys who swap gears and convertors can no longer register your car?

Something doesn't add up !

Good thing I used TTS to tune my PCM.

Those guys rock and roll..

TTS RULES! ;)

LMAO

Sounds like yet another way to get users to buy the Ease scanner you push so hard........

This time using less than ethical means.......

Sounds like you have a bug up your butt when people go out of their way to inform fellow Corvette owners with information and are muffed because a vendor is mentioned that the vendors who pay you a monthly fee do not sell..

What your trying to say is I forged that BAR public release and made up the I/M smog tests so I could somehow overnight own Ease and make profits.

What a joke, does the Corvette clubs of your readers get discounts for their members ?

So what is the difference ?
Its that I help people even if they are not on my team who by the way pay ZERO to be on the team and in fact I pay all the costs for the services they get.
So how come you don't care as much and pay all your costs without dictating who is a business and who is a club/team.

Did G.M make you a God in making these decisions?

Its really stupid to think because I can get someone a discount, that there is some evil way of making a profit when not one person can show I charged them a penny for my time.

Ask your readers, I have spent hours on the phone with most of them not only teaching them hoe to scan but countless hours donated to analyze their PCM traces.

So in the end you threaten to ban me unless I pay you a kickback monthly fee.

You got profit on the brain and when a Corvette owner attempts to help your people who are your sole content that allows you to charge those fees, you look for some evil profit reason.

You have no right to strong arm a club into paying you and you have zero proof I am profiting from a vendor giving a discount, when in fact I loose money all the time spending countless hours donating my time to your members, just to be supportive of you.

I think you need to go out and test scanners before bad mouthing your readers who did the work for you and hope you cn proof the less than ethical statements.

John,

I hope your not offended by me asking what would happen to all the tuners who might alter the pcm..

How could the guys who alter the pcm for cams or convertors or gears get by this nightmare you are stating is here?

I am sure...there is just a miscommunication.

I can't believe all these guys who make a living out of tuning cars are out of work because they touched the pcm..

Something doesn't sound right.

Corvettes are cool..no need to get hot under the collar..

This is a cool site..as are many.

Remember we all dig corvettes

As there always is, a lot more to this story than you would like to portray.

While you have contributed to this site, you misspeak yourself.

I'll save the members a response to this drivel, thread is locked and user is banned. Congrats our second ban in a year......
