EGR Disable

[jd4010]

I've been PM'ing with Bill at PHP and by the looks of it, I'm going to take his advice and do a FICM and ECM rollback. Did the math and at $300 for this service, getting 1 additional MPG would give me a payback in about 11k miles...so it should be worth it in the long haul.

I don't want to keep bothering Bill....he clearly has a lot of work on his hands. But, he suggested that when I get the FICM and ECM rolled back, that he also programs in an EGR Disable. He gave me 3 reasons for doing this including lower carbonization, some improvement in low RPM Performance and MPG increase.

So now I'm curious and coming to you all. What exactly is an EGR Disable? I'm bone stock....complete with EGR Cooler, etc, etc. So does this mean, literally, that the EGR is disabled via software and hence it would be like running a diesel w/o the EGR valve? Anybody else do this and how has it worked for you?

Inquiring minds want to know.....

Disabling the EGR valve will just keep it closed. The coolant will still flow through the EGR cooler and the risk is still there for that failure point. If you're planning to disable the EGR you should install a delete kit along with the software disable.

My EGR and oil coolers are relatively new ---- so I'll leave them as is and I'm running ELC with a coolant filter....so I should be set there.

However, is disabling the EGR a good thing as Bill suggests? I assume that not introducing hot air into the system is a good thing and it will cut back on the carbon, etc.

Just want to make an informed decision. So for anyone that has disabled the EGR via programming but kept their coolers and such intact, I'd love to know if you noticed any performance changes, pros, cons, etc.

It is a good thing, however you should still do some form of EGR delete/ blockoff to prevent coolant/exhaust from forcing it's way past the EGR valve.

So if I'm tracking with you, you are suggesting that the pipe(s) that supply exhaust gas thru the cooler also be terminated as well. Yes? If so, is there a part or something that disconnects and caps these?

Yes that is what he is saying.

The EGR disable feature via a programmer is a great idea, but is not the final solution to the problem...
You need to delete the pipe that supplies the exhuast gases...


you need a delete kit like this AND delete it with a programmer to not have it set of a CEL for insufficient egr flow resulting in a full delete...

Or a simple round plate samdwiched between the up pipe and EGR cooler, and an aluminum spool machined to replace the EGR valve, or a Bulletproof Diesel sealed EGR cooler, or many other solutions to mechanically defeat the EGR cooler/valve. because electronically disabling it will not stop coolant from entering the cylinders via the intake or exhaust in the event of a leak.
