Car Mods and Emissions
Last spring, I modified my car - and then modified it again.
The 2nd modifications entailed me re-programming (or flashing, or tuning) my car's computer. One thing I didn't realize at the time was that evidently, a standard protocol for most tuners out there is to turn off the O2 sensors which monitor emissions after the catalytic converters.
This doesn't mean squat to pretty much anything, unless the state you're living in requires emissions (or smog) testing.
I went in to have my car checked out yesterday, and lo-and-behold, it failed because 2 of my O2 sensors were in a "not ready" state. After a bunch of driving (trying to create "drive cycles" in vain) and googling, I found out that the tune I had installed in my car last year had in essence, completely turned off the O2 sensors.
So, the fix was easy:
I re-tuned it with my SCT tuner with a canned tune. In going through the questions, one of them was obvious, "Turn off O2 sensors?" I answered the negative, and was on my way.
I then spent last night driving around with a good friend of mine, and at one point, nearly missing a huge recently desceased deer in the middle of the road. Hehe... That was fun.
In driving around yesterday, I managed to create drive cycles for all but one sensor, which was fine, because in Utah, they allow one sensor to be in a "not ready" state, so... I passed emissions!
Also, as soon as I got my "all clear" certificate, while in the mechanic's parking lot, I re-installed my original kick-butt tune. Good for another 2 years.
Woot!

It is not cool that you brag about dumping hydrocarbons in the atmosphere. What makes you so special that it is ok for you to do it?
Selfishness is never cool.

Hey Sammy! Thanks for browsing my blog! And last, but not least, thank you for your wonderful comment.
Now, hmm... In response to your comment about hydrocarbons...
Would you care to chat about anything else? This is quite entertaining.
Now, hmm... In response to your comment about hydrocarbons...
- The car I purchased was purchased here in the good ol' U.S.A. according to local, state, and federal laws (including those pesky emissions laws).
- The modifications I have performed on my car do not make it any more polluting than it originally was. In fact, I've optimized it for fuel efficiency as well as more power, thus giving me more mileage per gallon, and thus reducing the hydrocarbon footprint of my car.
- How does my buying and modifying my car make me selfish? You have just as much right / possibility / capability / etc... as I do to go out and by your own car. I don't see the link between my buying a car I love, and my being selfish.
- The O2 sensors being turned off do nothing at all about emissions output on my car. The only thing it does is makes the car's computer able to process more at a time.
- It's good to see yet another person who subscribes to the belief that less than 200 years of data can prove that carbons put in air by humans is actually deteriorating the earth. Personally, I'd like to see more data before coming to conclusions that affect the way I choose to live, or even worse, cause me to interject my opinons on the way others should choose to live.

Sammy,
Dude, are you 12? Your voice sounds like you are a dork. Oh, and it smells like you might need a new diaper.

Looks like commenting works just fine, Sammy. Please - let us know what's on your mind.

Thank you for your reply. Regarding your points:
1. Why do you think emissions laws are pesky? Why do you think it is ok for you to break them?
2. Good! Just don't fool yourself by saying that turning off O2 sensors reduces emissions. You know it is not true.
3. It is not the act of buying or modifying a car but rather the thinking that it is ok for you to pollute more than others. That is selfish.
4. Why do you think the O2 sensors are there?
5. The law has already arrived at a conclusion for you. If you don't like it, vote or get into politics or science.
Finally, if you want to continue polluting more than others, fine. Just don't go bragging about it and encouraging others, because then you are multiplying the problem.

Yes, commenting seems to work if I don't use numbered bullets, but type in the numbers manually. Weird. Anyhow, thanks for letting me know.

Thanks for your response, Sammy. Here's what I have to say:
Thanks, once again, for your comments.
(PS - numbered bullets work fine, too. I used em' in this comment)
- Emissions laws are pesky in that they invade my lifestyle. If I have modified my car wherein it doesn't produce any more pollutants, yet it can't pass emissions, then yes, they're pesky.
- I never said anything about about the O2 sensors reducing my emissions. The tuning of the car's computer did.
- Why is it not okay for me to pollute more than others? My 4-month-old boy doesn't pollute at all. I'm sure I pollute more than he does.
- The O2 sensors are there to monitor emissions. Just because they're turned off, doesn't make the car produce more pollutants, it just removes the car's ability to monitor them.
- Would you mind stating which law you're talking about? I'm unaware of any laws stating that I need to force my opinion upon others to the extent that they need to alter their lifestyle.
- Why the comparisons of my being more polluting than others? There are those who pollute way more than me, and those who don't pollute at all.
Thanks, once again, for your comments.
