deleting EGR on full 3L

To do it right, you should physically remove both together, and have both disabled in your tune. I would not try to remove one and keep the other. Just me.

Even if you disable the DPFE some noted a while back that the ECU still checked for it on startup (only some cars). Try it without the DPFE and if you get a light for it then you need to plug it in and leave it there (no tubes running to it).

i agree. if you do it. do it right. and remove it from the ecu completly

You're not listening.... on some cars it doesn't matter what you do in the tune you still had to have it plugged in, even if the software supposedly disabled it.

so if u dont tune it out and keep the dfpe plugged but remove the system the check engine light wont turn on? then whats the sensor for?

You can't just magically "tune it out". It can be mostly ignored, but sometimes the sensor is still required to be plugged in to keep from getting a CEL. That's what he's saying.

and what they are saying is that some cars you cant completely tune it out for some reason. some cars, like yours and both my Zetec and SVT could have all of the EGR turned off so that even without the DPFE hooked up it wouldnt turn on the CEL. some cars though require that the DPFE still be hooked up, even though there is no EGR flow, in order to keep the CEL off.

Just a question... but why are you removing the EGR system? There are benefits for running it if you research it.

I deleted the EGR on my Lightning. Definately cleaned up the engine bay and makes plug changes MUCH easier.

Agreed for a full 3L swap. Eliminating the EGR just gives you more room for vacuum lines and whatever else you're changing to use the full 3L UIM. #49 is right about the benefits and it does not hurt performance at all. It's basically one small thing to make the 3L swap a little easier.

im sorry if i sound retarded here but what is this deleting the EGR do for the 3L.

it takes less time to delete it then to modify to make it work. makes the engine bay cleaner. pretty much the only thing that this will cause is hotter combustion temps while cruising

I believe you can get a compression cap from your local hardware store in the plumbing section, however I had a little trouble finding the correct size.
What I ended up doing was cutting the the EGR tube about two inches from the fitting that screws on to the header, I pinched it shut and welded it closed and haven't had an issue yet.
