OBDII emissions testing

Ok, so we all knew we could cheat the old sniffer test one way or another. But around comes OBDII and cheating is, well, all but impossible. I sat and thought on it, and the only way I could come up with to cheat was to take your computer out of your vvehicle(they read the vin in your computer as well as the one on the door) and put it in another vehicle thats the same year. Then either get a copy of your door barcoded vin sticker or find a tester you know who'll scan your door and run the other vehicle. Then pass and revert everything back

Well, that was too much. So, here's how I figured it out. Go buy a $79 actron OBDII tester from autozone. On the main menu, it has 5 options. Select the I/M monitors, and you can see what systems are ready and what systems are not. In Georgia, you can have one system not ready and still pass. There is a small amount of time between when those systems come online and that damn CEL comes on that you can squeak past the test. It took me three weeks, but I finally got it this morning. The tester will tell you when you systems come online, and you just drive real easy like to the absolute closest inspection station and wala. A new way to circumvent the system!

Ha, stick with older cars! Those sniffers are so easy to fool it isn't even funny. I used to run K-100 in the tank, which is a kinda "super-combustible" and makes everything burn better, and the guy would always be amazed how well the motor runs from the low emissions that were "way less than normal".

Isn't there PC software that mimicks those "scan tools"? You just buy the USB connector cable, install the software on a laptop and you're good to go. They let you tweak a lot more than off-the-shelf code readers. I'm sure you could cheat the emissions that way.

I've been doing that for years with my mom's 98 explorer. Someday I'll get around to fixing that stupid O2 sensor problem

Fortunately, I don't live in ATL so I ain't gotta put up with that BS for now.

But not trying to be a smart *** or anything, why not try fixing the root problem instead of scan tool trickery and cures-in-a-can?

The guys who designed the OBDII Smog Testing are a few steps ahead of you. When they do the OBDII down load, the computer's log will show you connected a tester/reader/computer to the car. And, the down load will show any fault codes you previously had. It varies by state, but you must have "X" number of miles driven since the last time anyone hooked up to the OBDII port.

Fortunately for that, GA just looks at system readiness. They don't look at the pending history codes (which are still clearable with my other scanner)

Quintin, I am coming up on 4 weeks riding an expired tags. My wife refuses to drive it, I had shoulder surgery two weeks ago and can't use my right arm for 6 weeks (and here come the reasons for my right arm........) and needed to get things back in order. I don't let others work on the Nav, to much crap I rigged my own way. Sooner or later, when I have arm movement, I'll change the O2 sensors and begin to hunt down the problem. But in the mean time, it runs like a champ.

just like microsoft was ahead of time with the unhackable windows XP... and it was cracked 18 hours after release...

the thing that happens is. people are hired to design this software for the new release. then some are fired cause they are no longer needed with the company.. well this disgrunteld employee gets a job with an aftermarket company like superchips or hypertech and they pay him to design new software that allows them to hide thier changes and or bypass..

Something security techs need to realize, is that there is absolutely no program or encryption that will keep people out forever. There's way too many geeks out there with no life that can spend all day in front of their PC trying to break these things. I guarantee "cracks" and exploits will be discovered within a week of Vista's release, despite it's security being touted as ultra-strong. Computers are just too damn easy to manipulate, which goes for PC's, car computers, portable devices, whatever. Chances are your cell phone can be hacked to get free ringtones or games, or to allow them to be sent for free over the carrier's network. Remember the "Cap'n Crunch" thing? Where some guy cracked Bell payphones using a 5 cent plastic whistle? Your car's computer is no different. Figure out the secret and you can make the shop's diaganositc computer think the car can fly. Just happens most people into cars aren't computer nerds so it hasn't really been done yet. Logs can be cleared, tracks erased. You could program it to say your car emits .015% I Can't Believe It's Not Butter out of the exhaust.

Some ways the internet destroyed any kind of security PC's may have, forever. Since it's mathmatecially impossible to create an unbreakable code(even if the odds are astronomically low, supercomputers now can try billions of codes a second), total security is impossible.

Sorry, guy, but theres absolutely nothing factual in your post.... If you need it, I can provide a link to Ford's documentation on how the OBDII system works, what is monitored, and what is accessible to a scan tool. It provides a good study in how the system works.

Steve,
I would love that link. I would like to read it. Not because I don't believe you, just because I would like to learn more about it. Thanks.

This is an example of the problem with these boards.
Steve, I and others come on and call attention to the things others post that are not accurate and it make heads hurt, taken as insult etc. and people will argue to cover up ignorance.
It's not our fault.
If people want to work on there trucks, they have to learn how they work or have a hard time of it.
Suppose you were to go to a medical doctor that had little knowlegde, how far would you get? It cost them 12 years of school to begin practice and they never stop learning.
Sorry if i get any hackles up but that's the way I see it.
