While I've got everything torn down, I thought I'd ask what all is involved in deleting the EGR??

Is it as simple as just not hooking it back up and blocking off all the holes?

I'm sure it's not, because that would be too easy!!!

So I'm guessing I'll have to have computer work done, among other things???

Thanks in advance guys!

I want to do the same thing. My LS6 intake is going on next week, and I would like to clean house while I'm at it. Finding someone with LS1edit is the obvious answer, but I am sure something could be rigged up. I will look in the manual to see what the signals are in the connector. Maybe a couple of resistors could fool the computer into thinking that the EGR is still in place.

 

I used a expandable rubber plug from Auto Zone (can't remember the size right off the bat but I think it was around 1 3/8" but that could be way off).

And just cut out a little plate to block off the flange on the header. I have a SES light but I don't really care because my engine compartment looks soooo much better. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I think there's a real good "install" procedure at www.installuniversity.com for eliminating (modifying)the EGR.

I got to looking into this a while back, and there are five wires that go into the EGR valve, on the PCM pin-out they are called:
"EGR pintle position sensor signal",
"Egr pintle pos. ground",
"EGR valve control circuit",
"EGR valve ground"
and the fifth is a white wire, I could not find in the PCM pin-out diagram.
Anyway, this "EGR pintle position sensor" is apparently no just an on/off type of signal. I took the EGR valve off the car and measured between the two wires for the "pintle position sonsor", as I moved the plunger of the EGR valve in and out with my finger, opeing and closing it manually- well the resistance between those two wires for the "EGR pintle position sensor signal" and "Egr pintle pos. ground", varies between about 2200 and 3500 Ohms as the valve changes position. So, best I could figure, as the computer opens and closes the EGR valve, it senses the position it is at. And if the computer does not see a CHANGE as it is supposed to be opening and closing different amounts, it will throw an SES code.I tried a resistor in the place of the "pintle position sensor" and that worked for a while, then I got an SES code that was something indicating invalid EGR flow rate or something like that... I forget the exact error. So I said to hell with it, disconnected the EGR from the exhaust manifold, blocked the exhaust with a home-made 1/4" steel plate, stuffed some foam filter material up in the pipe for the EGR input from the exhaust, and left the EGR tube to the manifold connected. This obviously does not get rid of all the EGR junk on the engine, but at least it keeps exhaust soot from being pumped into my intake manifold...and it throws no codes. Bottom line: if you wanna delete all the EGR and AIR pump junk under the hood, get LS1 edit or custom programming. If there was an easy way to trick the PCM, I'm sure somebody would have already come up with it and been selling it on the internet.
