However, I'll have to sell some stuff and save up to get it so it'll take a while - probably more like Spring next year.

However, I'll continue to move forward with the solid state conversion here in the next few weeks and will keep you all up to date on the progress. I'll go ahead and order the components to do 3 unless anyone speaks up and want's more. As of yet, it's untested and just theoretical so keep your fingers crossed!

I'm one of the "Gang of 3" right?

If you can do it, I don't see why we can't wait for "Part II: The delete of the EGR" to come along.

Yes, you, me and mdisav. The replacement tube is just a performance enhancement. The electronic part is the only essential component right now.

Just another update, the solid state relays are not $12, they're $22. I'm only going to order one right now. I don't want to blow over $60 of they don't work...

What is the latest on Part I of the delete?

KarTek · #79 01-11-2009, 11:54 AM

Still going perfectly. When I fixed my GP late last year, I went ahead and removed the heat pipe and fabbed up a block off plate for the exhaust.

I'd swear that I'm getting 1-2 better MPG. I used to rarely make 31 MPG on long trips, now it's the norm and I'm doing 26-27 in town where I was only making 24-25. It might be the GP repair though...

I've been hibernating lately and not doing much on the car. Except for yesterday and today as it's been in the 60's. I've been fighting with the duo-valve trying to get heat out of it. I finally broke down and completely tore it apart and every piece of rubber was completely shot. Nobody makes a rebuild kit as far as I can tell and I refuse to pay the $240 for a new one so this is another thing I'm trying to come up with a cheap, reliable solution to.

As far as the future permutations of the EGR delete project, I plan on ordering the solid state parts soon and I've come up with a design for a piece that completely removes the valve assembly. I'm trying to "dovetail" this project in with my ST project so I hope to have some dyno numbers that would show any improvements.

What do you think would happen if we blocked off the EGR pipe from the exhaust end and stuck a valve cover breather filter onto the EGR end? That way, when the EGR activates, it just sucks fresh air instead of the exhaust fumes.

KarTek · #81 01-12-2009, 08:56 AM

It'll set a code because the ECU looks for that drop in flow across the MAF caused by the force of the exhaust pushing through the EGR. If there's an open/filtered air supply, that positive pressure won't be there.

So when do you sell the electronic kit?

KarTek · #83 01-17-2009, 02:36 PM

Hey, got your email. I can stop by RS this week and pick up the parts to make one like I have on the car now. I can whip it together pretty quick and I'd send it to you for $20. If you're pretty handy with the soldering iron, you should have no problem installing it. My setup has been working for close to 6 months now without a hitch but I'm still experimenting with a more permanent, less mechanical solution.

It should also eliminate your EGR code.

Seems like my EGR froze that day and tripped the code since it hasn't come back yet. Still I would like to have it not function at all so that it will not have soot in the intake tracks.

I think I am pretty decent with a soldering iron. How is the more permanent solution going? Any foreseeable timeline? IF it is a little while more, I might wait but if not, maybe the $20 solution will work till you get it done.

I have pretty much stopped work on the car now that it's winter because of other pressing projects. If I got back on it, by the time I had it assembled, installed and gave it a reasonable test period, it would probably be mid-March.

I too am watching and waiting for the Electronic EGR Delete Release 1.0...

I cleaned out the IM last spring while doing some maintenance (~110,000miles) and don't want to have to deal with that goop again.... The car ran like new after that...

PS Amazon had (last Night) a sale going on including some anime and Gun Slinger Girls was listed so I picked up the set for about $22...

I'm definitely interested in buying a kit if you are making these. PM me if/when they are ready. I can't wait to delete the EGR. I hate cleaning the IM every time I take it off. This is an awesome thread!

KarTek · #88 01-19-2009, 12:59 PM

OK, I'll get off my lazy butt and finish with the development of the final solution...

Olivier · #89 01-21-2009, 04:07 PM

Hello KarTek,
I live in Scotland, any change you could post a kit over here? I could use paypal if this is OK with you.
This is the first time I could find someone who stopped the EGR. Brilliant. Great.Superb!
I drive a E300TD, 1997, 91000 miles on 90% WVO
Thank you.
Olivier

Any chance this would work on a 602? Like the 92 300D?
