I was reading a lot of the older posts on the SEGR but haven't seen it mentioned recently. Is someone still supplying SEGR parts, or does the GDE tune do the same thing? Thanks, Loyd |

Thanks, Loyd Demand for the SEGR dropped when the GDE tune came around. You might be able to find a used SEGR or one that was ordered and never installed, They do come up every once in a while. Install requires splicing into the wiring harness. SEGR only addressed one issue, the EGR. In my oppinion, GDE tune is the way to go. It fixes a lot of things that Chrysler didn't bother to optimize and no need to cut and solder. |

I had bought an SEGR Kit and never got around to doing it... then got a GDE tune. GDE tune Does so much more and makes the Jeep run better with more smoother power IMHO. It costs more but Far less work to install, nothing to cut into and the mod is nearly trasnparent to anyone that works on your vehicle. Kieth is a great guy to deal with too. I sold my SEGR kit to another member. |

If you don't want any EGR going into your engine with any option (ORM, SEGR, GDE), you need to put in a plate. The way I plan to plate is with a thin piece of stainless steel (shim stock) going between the EGR pipe to EGR flange. The plate will need to go between the two bolts so you can slide it in and tighten up the bolts. Unlike gassers that can kinda benefit (cheap octane booster effect for low octane gas) from EGR, EGR is there for only one reason on diesels, "LEGISLATION" created by Acid Head Hippies! |

I personally have and like both and while the GDE tune does a lot of good things, including dramatically reducing the use of the EGR, it does leave it open a little during some run operations. The SEGR, on the other hand, completely removes the power to the solenoid that opens the EGR valve. Functionally making it closed all the time. I already had the SEGR when I got the GDE tune and it didn't make any sense for me to open the EGR back up (a little) when it was already functionally disabled. Warp, I'm not sure how removing the power from the EGR so that it's closed at all times doesn't functionally equate to putting in a plate... Dan |

Dgeist is on the same page I am - None at all is better than any amount. With the GDE tune, every single time you remove your foot from the throttle, the EGR is commanded to open for a half-second. Do I believe that the electric component of the EGR will survive a lot of cycling at such short durations? No. Do I think that the EGR would even open at all with such a short duration? Probably not. However, I have the trifecta: SEGR electrically severing the power to the EGR, while keeping the computer nanny-systems happy. GDE, reducing the use of those nanny-systems (and the programmed usage) of the EGR itself to near-zero... And finally - Complete disconnection and removal of the EGR supply pipes. From the manifold to the EGR, then from the EGR to the intake elbow... Nothing exists except a welded-shut flange. It is still un-doable if for some reason I wanted to go back to stock... But I don't see that happening ever. And my dashboard remains quiet and peaceful without the CEL on, unless there is a decent reason for it. |

I'm an SEGR man myself. For off road use only of course. |

Flagrant disregard? Who, me? Hehehehehehehehhe Granted, but I figure I am safe for 3 big reasons: 1:People still give me a dumb look ALL THE TIME and ask "how much did converting that to diesel cost?" or "really? That is a diesel?" 2:where the tubes were located, you would need to KNOW that they were there to even look for them. 3:My vehicles are all registered in Florida, no matter where I happen to be... The South doesn't believe in any kind of inspections outside of places like Atlanta... And I'm not certain about inspections even there. I'll just keep my registration in the cheapest place available, and stuff the inspections. Not that they would know where to look anyway. These jeeps are too rare. |

I seem to recall the reason for the short boosts Gordi mentions is to lessen the turbo spikes that occure under those condition  Anyone noticed the growing number of rate turbo's failing  Could that spike possibly be related I understand their are 39 on national backorder

I don't want to speak for GDE, but.... I don't think a legit company can expect to bypass the EGR altogether and fly under the radar of the CARB drones.... Programatically evening out the turbo spikes is a ...plausible... reason for opening the EGR, but then so is being in compliance with state/federal emissions non-modification law. Just saying... I'd suspect improper cool-down procedures and dissimilar metals are more likely causal for many of the turbo failures... Dan |

Not to do any “Horn Tootin” here but I like both. SEGR and a tune. Some of you newbs here have to appreciate the time line of events that got us here. First there was the ORM or just unplug the MAF sensor, which was much better than leaving it plugged in. Next was a major breakthrough with the SEGR. (Thanks to all that helped) No EGR and No CEL. Then after all of that came the “Tunes” and all the benefits with it. I just did an EGR delete and a tune on my 06 VW Jetta and WOW!!!!! A tune for the CRD is next! |

I have SEGR installed, but I run with the bypass plug installed when the GDE HOT ECU is in place. I share Dgeist's concern about over-speeding the turbo on over-run. Thanks, DOC |

Thanks, DOC I ran mine with the bipass plug in after I got the GDE tune until a couple of months ago. I reinstalled the SEGR and my fuel economy went up 1.5 mpg, (last two tanks have been over 28 mpg, hand calculated in-town driving) all things being mostly the same since I'm in Arizona and there wasn't a #1 to #2 diesel change, only a warm up in the weather. I'm convinced that shutting off the EGR completely is a benefit. Only time will tell on the turbo wear..... Gary |

Thanks, DOC I appreciate the support, but my comment was suggesting that it turbo over-spool ISN'T a big deal....but not observing a proper cool-down is, and that I think running the two solutions simultaneous is the best of both Dan |
