Is there any advantage in running a SEGR in conjunction with a GDE tune?

The GDE tunes use the EGR valve, and the SEGR disables it, so they are somewhat incompatible.

I hate to sound like a mother hen, but I need to hear from the following members if they want in on the SEGR buy:

At the moment I don't have enough people buying in to cover my costs, the PCBs are too expensive in low quantities. Folks who have paid will get refunded if I don't get at least two more paid by Thursday the 21st.

And if you have sent payment and I have not acknowledged receipt, please let me know.

I have received enough funds to get the buy off the ground. I will buy enough PCBs to make the piece price work out for the cost of the kit, but I will only be ordering enough of the rest of the parts to fill the paid orders. So if you still want one, I will have spare PCBs and will order more parts to fill orders as necessary, until I have no more PCBs.

I will be placing the orders tonight and tomorrow, and I expect to ship kits as soon as the PCBs come in, most likely late next week, March 7 or 8. Built boxes will likely take another week.

Thanks!

Correct, and not a problem. I ordered enough parts to cover a straggler or two.

Is it too late to get in on this? I'd like to get an unassembled kit.

Thanks,
Jim

No, I ordered extra PCBs, so I can make another parts order to fill more kits. PM me for info on payment.

Update:

PCBs and parts arrived. I put together and tested the first article and verified the kit contents.

I have put together the parts for those who want to assemble their own kits and will ship those Monday.

Greasy Bob, your box and harness is assembled and will also ship Monday.

I expect to finish building and testing the rest of the kits by the end of the week. If anyone is curious, I posted pictures of the new box build:

I just joined this lost Jeeps forum. I've been having problems with my EGR all Winter. Do you still have an SEGR kit available? I guess if you don't I can breadboard one. I'm not a car guy.

Question: Do all diesel cars and trucks sold in the USA recycle crap like that back into the engine? I just cleaned my MAP sensor and was kind of amazed at the gunk on it. I've also been told that the EGR is what makes the oil go black so quickly on a diesel. Right now I am running with my MAF sensor unplugged and plug a PC and adapter into my car to turn the yellow (CEL) light off.

It's difficult to find a good description as to how the EGR actually functions. Is it strictly actuated from the MAF? Is temperature a factor in whether it is open or shut?

This is the first Jeep I've owned and I find that if they are all like the Liberty diesel, I want no part of them in the future. I've had this since 2005 and it's been a finicky vehicle with poor traction unless you are in 4 wheel drive.

UFO...Has any SEGR user completly removed the EGR system. If yes, any issues?

I do have parts left for one more kit, and I also have a number of PCBs, so I can order parts for some more kits too.

EGR has been used on all light diesels for decades. The CRD sticks out in the sheer volume of EGR circulated. My MAF sensor was completely crusted over when I bought my CRD with 35k miles. I checked it a couple months ago now with 116k, and it was completely clean. No questions in my mind that EGR is harmful for diesels - I have built a solution for my '01 VW TDI as well.

The EGR system on the CRD functions using the MAF sensor as an input. When the ECM calculates engine conditions for a certain amount of EGR, it opens the EGR valve and closes the AFC valve a bit, then monitors the MAF to validate that the proper amount of EGR is flowing - the MAF will show less air flow as more EGR flows. So the SEGR intercepts the commanded EGR and AFC, and modifies the MAF signal to the ECM, fooling it into "thinking" the EGR command was effective.

Temperature may affect how much EGR is commanded, but all the SEGR does is reflect the commanded EGR level back to the ECM.

I don't know. However, if the components are removed and properly blocked, the only issue I can see coming up might be an issue with shutdown as the AFC (air flow control) no longer works. The SEGR will still operate the AFC when the transmission is in P or N, to help with engine shutdown. The AFC may allow shutdown in case of a runaway condition as well.

Most SEGR users are not interested in taking the time to remove the components as the EGR is completely disabled already. However, sometimes the AFC and EGR valves fail in the open position, and the only option is to either remove and replace with new, or remove and seal off. In either case, the SEGR can still be used to keep the engine light off.

newbie here right from EGR/smog check hell. I would be interested in a SEGR kit if they are still available. If so How do i make the arrangements for payment and shipping?

I have one more immediately available, and if I continue to get interest I will make another parts order in 2 weeks or so. Just PM me and I will give you my Paypal address or postal address depending on how you prefer to make payment. Shipping in the US is covered by the price posted earlier in this thread.

I got all the kits assembled this weekend, I still need to test them and print copies of the instructions. I should get all remaining orders shipped tomorrow. Thanks everyone.

UFO · **Posted:** Tue Mar 19, 2013 3:18 pm

Everything is now shipped. PM me if you want to track shipments, I used USPS, insured.
