Have a 99 ls1, want to throw the ls6 manifold on, but they are starting emission testing here in PA. I know i can have it removed by using ls1edit, but when they plug me in to check for codes will they be able to tell its missing? Anybody ever change up to a 01-02 pcm to have no worries?

 

I had the same issue. Got rid of everything but the EGR.
I took it off the mount moved it and the harness over by the A/C lines. The PCM is looking for a voltage change ( feedback ) to the PCM. No codes, no problems, No LS1edit.

 

really that worked? cool! I was thinking it would have measured something, but guess its only more/less a valve. i never thought about doing that, thanks

 

No problem. By the way if you already SES coded for this, hook the EGR back up and it should clear the SES after 20 key cycles.
It's nice to have buddies with TECH2's also

 

so would it throw a code if i had it all wired up but i cut the hoses off so air went inside one end and out the other?

 

I think that would be the best setup. I did forget to mention you should ground the EGR unit, or install it as you suggested. The only down side would be you have cut up a part you may want someday.

 

i'm trying to sell the car and the SES light was on because of it. it makes ppl instantly turn away when the ses light is on
