Woohoo! No more emissions for me!

Time to go true dual straight's. I'm gutting my truck of any unnecessary emissions control crap.

[Joe Gress]

Haven't had to do emmissions since 2005 here. My car would pass though, the fumes just go into the cab.

"The decision to give older cars a pass will also send more pollutants into the air until 2018."

Great.

"Cars built before 1996 require more expensive testing."

Oh, so its all about saving money vs the environment. Most unfortunate.

This assumes the environment needs to be "saved".

Seriously, don't remove the pollution control devices from your vehicle simply because the government will no longer check. Here's why:

-Removal of the catalytic converters will result in increased (10x or more) emissions of hydrocarbons and oxides of nitrogen (NOx)
-Removal of other emissions controls may cause the sensors signaling your engine management system to give false readings or fail, resulting in your computer entering a "limp home mode". This will likely cause a drastic drop in fuel economy and power as well as increase in emissions.
-Some of the emissions controls are integral to the systems which help your vehicle start when cold, run properly until fully warm and respond smoothly during rapidly changing conditions, such as sudden acceleration.
-It's still illegal to remove or alter the emission control system, even if they don't actually check and you can be held liable.
-If you sell the vehicle to someone who does have to pass emissions, they can come back to you after the vehicle fails and sue you for their money back. If you've removed the legally required emissions controls, then you will lose.

Uh, note I said this specifically... "UNNECESSARY". I know which things can or cannot be removed. Unlike most people, I actually know a lot about my vehicle and do all of my own work. There aren't all too many things in my truck (1994 Bronco) that control engine operation, except for obvious things like timing advance etc. The computer is pretty limited compared to what comes in cars now.

Sue me? I would be upfront and list it has straight pipe exhaust...

I'll take your word for it that you know what you're doing. But 99.999% of the public doesn't know this and I've seen people tear stuff off of their engines thinking they're going to get better gas mileage only to have their engines run like crap.

As long as you get it in writing "off road use only".



BTW, will you be using some kind of after market programmable engine management system to customize your fuel and spark to get more power and fuel economy that's possible without the cats?

[Joe Gress]

Pshh, lose your muffler like mine. It sounds better and passes every time!

You mean an ECU swap? No.

My muffler was already off.

[Joe Gress]

How did your's go? Mine was lost in a snow drift coming home after a snow storm. Dad came home that night and handed me the empty can. (it was pretty shot anyways though)

Catalytic converters only have something to do with engine running when there is an O2 sensor after the cat (unless it's blocked, then it'll affect engine running in a bad way). Other than that, they are nothing more then a chemical reaction chamber...

[Ericman197]

O2 sensors after the cat have no effect on how the engine runs. They're only there to give a check light if the cats are fouled.

The only emissions equipment I'm running on my Duster is, uhhh... PCV and a carbon canister that's only hooked up to the fuel tank. It may be a carb'd car, but I like to do what I can to help the environment

The only thing I would want to do, issues of OBDI aside, is put in headers and a non-EGR intake manifold.

Much like my large intestine

[fenderhutz]

I got this confused with the vasectomy thread due to the title.

Carry on.

Not really a "swap" to a different ECU, but to a user programmable controller like this:

I use one on my '78 Mercedes

That's true. But the ECU is programmed to keep the air/fuel ratio at a constant 14.7:1 because it's necessary for the proper functioning of the cats. With the cats removed, the ECU can be reprogrammed to run richer at wide open throttle for more power and leaner at cruise for better fuel economy. Doing this can easily save 15% in fuel.

Woah woah woah, let's not turn this into a global warming debate. Let's stick on the casual topics like smog or religion.
