egr delete19ss99 11-19-2003, 10:32 PM 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? 2000zee28 11-19-2003, 11:14 PM 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. 19ss99 11-19-2003, 11:19 PM 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 2000zee28 11-19-2003, 11:24 PM 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:D chpmnsws6 11-20-2003, 12:34 AM 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? 2000zee28 11-20-2003, 08:39 PM Originally posted by red91tsiawd 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. chpmnsws6 11-20-2003, 09:12 PM Originally posted by 2000zee28 I think that would be the best setup.
