| Post subject: | SEGR |
Newbie to the diesel world, i have read through a bunch of post on ORM and SEGR, i understand the ORM, but i would like to know were i can get a SEGR, i just purchased an 2005 Liberty CRD and i want to do everything right, i just need to know were to go to get the parts or how to put my own together. |

Sorry for the slow response. I moved the topic to the general CRD section. The builder's thread is here: viewtopic.php?f=5&t=23033&hilit=circuit |

SEGR is a great product and it works perfectly when properly built/installed. Also, it is essential to keep the EGR valve closed almost ALL the time or your intake manifold will plug up. And, unlike a VW TDI, it is hugely expensive to clean it. However, unless you can build the SEGR and install it yourself, it will cost almost as much as a GDE ECU tune which disables the EGR 99% of the time. The SEGR level of difficulty is WAY beyond that of the backyard mechanic. I had the SEGR installed before GDE came on the scene. (Parts, assembly and professional install ran about $450. And, that was from an electrical wizard who is a LOST member who only charged me 1/2 his rate. And, he had just done the install on his own CRD so he knew EXACTLY how to proceed.) It is still installed, but I have it disabled because the GDE ECU makes it obsolete. I do not believe any of the other CRD "tuners" offer an EGR "disable" with their tunes, so this makes GDE by far the most economical for most people. DOC |

Salden, I think I paid about $325 for my SEGR (including assembly by UFO) and GDE's tune is $450-$500. The tune has some other advantages if you want to get away from the stock tune. FastRob's offer to sell you his is probably a less expensive alternative if that's an issue for you. The wiring isn't a big deal. I used a multimeter and a pin to verify each wire I needed to splice before cutting into it. (test continuity between the pin in the connector and the wire using the pin to puncture the insulation). I soldered and shrink wrapped all my connections and it took me about 30 minutes to do the install. If FastRob didn't get UFO's kit and bypass connector it may be worth PMing UFO to see if he has any extras around. |

I also have an extra for sale, built by UFO, if a second person is looking for one. Just PM me. EDIT: SOLD |

I built my own SEGR from the kit and installed it myself back in NOV. 09. The kit build was easy and fun and the install was not hard at all. No brain surgery experience required... IT Works great BTW |

I agree the SEGR is a great product - I wish I'd not waited as long as I did to get off my butt and install it. However, it is NOT for someone that doesn't understand basic electrical concepts, soldering, crimping and troubleshooting. It's a tedious install to get into the wire harness bundles and find the requisite wires, cut, splice, solder, etc. all the while keeping which wire is which straight. Doesn't help when you get overconfident and button up everything prior to testing only to find out something is screwed up. I had to take it all apart again to find out I totally whiffed it and spliced into the wrong wire after properly identifying the RIGHT wire..... Duh....... All I'm trying to say is there are some people that have no business playing with a soldering iron or the wiring under the hood of their vehicle. These are the same sort of people that used to bring in an R/C car to the hobby shop I worked at (long time ago) that was a basket case of misassembled and broken parts and duct tape and chewing gum holding the wiring on. Screwdrivers are dangerous in the hands of these people - mechanical murderers. |

Turbo Tim invented it and posted drawings and parts list. UFO builds them. I built mine and still need to install it, running ORM for now. What I like about the SEGR is that it shuts off the  EGR. Tricks employed by chip tuners to shut off the Check Engine Light only greatly reduce the amount of EGR, not eliminate it, Legislation prevents them from doing so, read the fine print in the disclaimers. The EGR on Diesels only controls NOX emissions that were determined to be evil by Acid Head Hippies back in the 1960s, most likely do to the fact that NOX causes uncontrolled laughing and the laughing exposed the Acid Head Hippies for the Idiots the are. Other sources of NOX are Agriculture (Including Organic) and Waste Water Treatment. To be honest, you have to have almost perfect laboratory conditions to generate any smog from NOX, change one variable and it won't happen. When we had a Smog Alert in the Greater Chicago Area a few years ago, Lawn Mowing was banned for a couple days, not driving diesels. More proof the Acid Head Hippies were/are Idiots. Another way to control NOX is by injecting Urea into the exhaust. I am waiting to see the first Home Brew Urea Reactor, bet ya it will have a toilet on top to collect the natural fluid needed to make the urea. Besides it would be more environmentally friendly to make Urea from human urine than to crack natural gas and emit all the evil CO2.

By "hacking" I meant cutting into a wiring harness that resides in a hostile enviroment under the hood of a jeep. To me that's just asking for trouble down the road no matter how good you think you sealed it up

I finally got around to installing my SEGR. I got mine, thanks to 'Yakers' selling his uninstalled unit. I was very careful making the cuts, splices and taps. I probably spent about 3-hours from start to finish. It is, visually, an almost undetectable installation. I still have a CEL, and the one code, I can't read on my code reader. It is code #1140. The other code is P0069. I can't erase either of them. I will stop be Advance Auto and see if they can read and clear the codes. |

I think you are confusing your NOx's, with N20. N20 is nitrous oxide, NOx is nitrogen oxide(s) NO and NO2.warp2diesel wrote: Other sources of NOX are Agriculture (Including Organic) and Waste Water Treatment. I don't think that is correct.

I don't think so on that one.. Agreed on the changing of one variable... instead of NOx, you used a grapefruit, yep, you guessed it, no smog. warp2diesel wrote: When we had a Smog Alert in the Greater Chicago Area a few years ago, Lawn Mowing was banned for a couple days, not driving diesels.

I've triple-checked my installation of the SEGR kit. I've replaced the MAF sensor. I still have a CEL. With the SEGR plugged in, I am getting the following codes: P0102; P0069; P1140 With the bypass plug connected, I get the exact same codes. In both cases, my code scanner also displays 'misfire' and 'EGR'. I can never erase the P1140 code, and occasionally can erase the P0102 and P0069 codes, which come back immediately. I also noticed, that if I start the engine and then try to erase codes, the CEL goes out and immediately comes back on. I'm totally whacked out by these CEL and codes issues. Also, since I moved the filter/head assembly to gain access to the wiring trough, I am getting a huge amount of 'limp mode' occurrences, with air in the fuel. I guess I disturbed the infamous fuel line fittings. Signed, Totally Frustrated! |

I can can tell you that there is a difference in millage and performance between using the ECO Tune and just inhibiting the EGR by ORM or SEGR. My jeep is living proof! |

There is a method you can use to splice into wires without cutting them, take your pocket knife and remove about a 1/2 inch of the outter jacket, then take a small screwdriver and split the wires in half to make a small hole, insert new wire in the hole and twist it around your original wire, apply a small amount of soldier and tape around the entire splice with some 33 plus tape or equivilent, then if you decide to remove the segr system at a later date you don't have any actual splices inyour original wireing harness, you just have to heat up the soldier to remove segr wires and then tape the exposed area of the wire up. There is a write up for this w illustrations on a different forum, when I find it ill post the link to it on here. It makes for a much cleaner installation, the illustrations on the link ill post will clear up any questions. |

That's great for a TAP, but a splice is going to require a cut-wire, no matter what. |
