Im getting ready to ship my computer off to madz28 and this spring im going to pull all the egr and air crap off my car. Will it hurt to go ahead and have him disable them through the computer while they are still on? Or should i wait untill I actually have them off before its disabled? Thanks guys

 

It won't make any difference.... niether system operates that much when it isn't programmed out, and it won't hurt if it just sits there when it is programmed out.

 

take all that emissions crap out (except your cat - always leave your cat in), throw it on the ground, stomp it a little, douse it with gasoline and set it on fire. Then proceed to urinate on it while expelling your feces on to it at the same time. Then after that do indian war dances around the firey mess of emissions parts and human bodily waste until the car Gods come down and take all the tree hugging environmentalists (who put that crap on your car to begin with) and spank them for being so naughty and moronic....

just my $0000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000.02

 

Yeah when I had my car tuned the tuner turned off my emmissions crap and I still have it sitting in my car. I am gonna start tearing it out off my car also though.

 

Actually, EGR can help improve performance and fuel milage when operating at low RPM/moderate loads. And it doesn't harm WOT performance in any way.

 

Im not worried about the performance gains, I just think that it cleans up the engine bay a little. Thanks alot for the replys guys, I'll just have Ion disable it

 

Injuneer, can you explain this:

"Actually, EGR can help improve performance and fuel milage when operating at low RPM/moderate loads."

Can't see how EGR (recirculating exhaust gasses) could end up improving performance and mileage.
I'm probably overlooking something so please enlighten me.

 

the recirculated exhaust gases undergo further combustion, which releases energy, which should in theory propel the car. Thus the increased performance and improved fuel economy when you are cruising on the freeway at 1700rpm and say 5% throttle.

 

The EGR only operates during cruise operation in closed loop. It does not operate cold, at idle, or at WOT. It's biggest intention is to reduce NOx emissions which are most prominent during cruise when lean mixtures are present. The exhaust gases that travel back into the combustion chamber actually cool it down, which means less NOx. An advantage to this is that the exhaust gases take up space in the combustion chamber- I'm not really very good at explaining this part, but yes it can actually improve fuel economy slightly.

Of course, the disadvantages are more clutter in the already cramped f-body engine bay, carbon deposits clogging up the egr valve and lines which will set a code and may cause driveability problems, more soot in the intake manifold, costly repairs, fitment problems with aftermarket headers, etc. I ordered my headers without the emissions fittings simply because I don't plan on having a cat much longer, so the whole emissions compliance thing goes out the window anyway, and i figure that with a low operating temp of 180-190 and a long duration cam I'm throwing in soon my NOx emissions will be quite low, but CO should be through the roof. Oh well... Later this year my LT1 will most likely become a weekend type car, so I won't feel so bad since I'll have a "green" car for the week.

 

For the life of me, I can not see how the EGR system causes any "clutter" in the engine bay... its all behind the intake manifold. I managed to keep all that stuff functional on an 800HP nitrous/stroker LT1, and it didn't hurt my performance, or get in the way of much of anything I had to do under the hood. AIR is obviously a "clutter" appearance wise, but the problem with EGR escapes me.

I did remove the EGR, AIR and EEC when it became a "track only" car, because is was no longer functional..... didn't think I needed an EEC system to purge the vapor out of a 5gal fuel cell full of C16

 

how do i remove the AIR in my car? it keeps blowin the pump fuse so i figure why not take it out?

 

There's a recall on the 95 and newer AIR pumps.... you could get a dealer to fix it for free. If you don't want to fix it, simply unplug the harness connector from the pump, and then put a good fuse in the circuit. No codes set for that in OBD-I.

 

any GM dealership? can u give me some more info on the recall? i have a GM dealer right down the road.

 

Try a "search" or look on ALLDATA for the recall number. Also might want to check on Shoebox's Tech Pages, because he has a diagram showing the recall changes, and the number might be on the diagram.

Well, not visual-wise as far as clutter is concerned, but when I put my headers on I want as few things to try to hook up as possible, less chances of leaking, etc.
