I have read all the threads and I have all the symptoms- the white smoke, the surging, the pinging on acceleration...all of you that are experiencing these symptoms of the ongoing threads... are all of these symptoms only with having the Edge installed?

I am thinking that once this tank is empty that I will uninstall the Edge on my truck and if all these symptoms are gone I will just sell the Edge. I am happy with my truck besides these tiny issues.

so basically.. is your truck stock or do you have the edge installed? I hear most are caused by having the edge installed.

thanks

I'm 100 percent as it came from the factory and, so far, no problems what-so-ever. Maybe the only person on this forum who does not f around with the unit trying to make it into something it was never intended to be. Almost all troubles described here are on vehicles that have some modifications intended to enhance performance in some manner. I'll probably catch some garbage for stating my opinion but, that's the way things go. Be interested to hear what happens when you remove the Edge.

nothing wrong with stating your opinion.. doesn't bother me at all. I am not after the tire smoking power that some look for. I just want a good tuned truck and good economy, BUT..if the edge is causing these problems then its gone. I have no problems leaving it stock at all. As I said, I have a few more days on this tank and I will remove the edge and see. Don't be surprised if you see my Edge for sale soon ;-)

I also wrote into Edge and asked them about the issues and if they could be fixed or not. Depending on what I read about everyone having the edge installed or what I hear from Edge..I will remove it and sell it. For what I paid for this truck, like everyone else, I want it to last a long time.

I do not have the white smoke or surge problem, but my bone stock LLY (built 6/4/04, 4,000 miles) pings like a high compression gasser running 87 octane.

cool, thanks. Mine had that sound as well when stock and it sounds just like what you describe, had to get used to thinking I had bad gas.. lol

I will narrow this down once I pull the Edge out for a few weeks. If there is no smoke or pinging..then bye bye Edge!

Nothing wrong with opinions, everyones got their own. With that said I will say that "in my opinion based on my own experience", I had approx. 2K miles on my LLY when I installed the Edge and now have 10K miles. During that time I've had one issue, it was the dreaded "knocking/pinging" during the warm-up period and the surge. This issue was eliminated when the dealer reflashed the PCM with the latest update. Truck has always run great. I'm one of those people that like to have just a little more power, but not for racing, burning tires, etc. "In my opinion" (if you haven't already) take the Edge off your truck then get the dealer to update your PCM to eliminate the ping, surge and white smoke. It worked for me. ;)

funny.. there lies another problem for me..I am having a hell of a time getting this flashed.. 4 dealers so far here locally.. I gave up. The last dealer said they know about it and can do it so I drove the 30 miles to have them do it and I always wait for my vehicles..personal preference.. 30 minutes later he comes and says the Diesel guy was not going to be there for 2 days. WTF? I drove home. very disappointed with dealers at this point.

I have tried 2 GMC dealers and 2 Chevy Dealers.. only this one GMC dealer knows anything about it and one Chevy dealer knows about it, but won't do it.
anyways

lol..I plan on removing the edge in a few days. I too like just a little more power, but not for racing purposes

thanks for the input

Briano,

Were you ever able to find a dealer to do the 9/10/04 reflash on your LLY? I am thinking you posted previously that several dealers where giving you a bad time about doing the reflash.

As I am sure you have read, many other LLY Edge users had the smoking/surge problem cured or greatly reduced following the reflash. You should definately get the reflash done before dumping the Edge. The Edge was not causing the problem on many of these trucks, it just brought an underlying problem to the surface.

As I recall, there were a couple of posts saying the reflash did not help, but then they found out they had injector issues.

If you had the reflash done, and the injector balance rates are good, then try a tank or two running Stanadyne fuel additive to see if that makes a difference.

If all of that fails to help, then let the sale begin!

Since there are so many LLY owners not having problems with an Edge installed, following the reflash, I have to wonder if there is something out of spec on your truck.

Good Luck.

thanks.. and yes I am having no luck getting this flashed around here..very frustrating. The GM folk have no problems, but its the GMC's they won't flash. Something about GM won't pay them or something..basically they don't want to do it.

Sorry to hear that the dealers would not flash the truck.

No matter what you do with the Edge, you should get the flash done. I could tell a difference in my truck immediately after picking it up from the dealer. It was much quieter, and smoother....and that was stock. The idle was getting louder over time. It now sounds just as it did when I first took delivery. This makes me think the problem(s) the reflash addresses, get worse over time.

Here are some suggestions to get them to flash your truck:

- State the problem using terms similar to the notice documentation. In my case, I said the truck had an intermittent knocking when warming up and also would sometimes surge at low speed in first gear. I also mentioned the notice addressing this problem.

- Speak with the Service Manager, not the service writer. Tell him you have been very disastisfied with the service given your truck. Many dealerships have a "completely satisfied" policy since they do not want the customer to return a negative survey to GM. A poor report record can hurt them on future vehicle allocations. Let him know that you are not satisfied, you are planning to return the GM survey card with unsatisfactory marks (asssuming you received a survey card after the previous visits), and that you are planning to open a case with GM to get these problems resolved with you truck. Then tell the Service Manager you would like to give him an opportunity to rectifiy these problems (ie: do the reflash) before taking these actions. If he is smart, he will realize it is easier to do the reflash than to deal with your complaint to GM.

- If the Service Manager still doesn't get the picture, talk to the General Manager or the dearship owner. Ask him or her if it makes good business sense to have an unsatisfied customer complaining to others about the product and the dealership when it can most likely be resolved with a ten minute fix.

- If they still don't get the picture send in an unsatisfactory survey and open a case with GM.

- Be assertive, but keep it professional. If their response is unacceptable, then tell them what they are offering is unacceptable. If they are smart they will realize they will not be able to brush you off and will do what is right.

As I recall, MasterP2 had similar problems getting the GMC dealer to address the A/C TSB. Maybe he may have some suggestions for you. Also, maybe some of the Techs know how to get a reluctant dealer to step up to the plate and do the reflash.


Be sure an remove the Edge before taking the truck to the dealer. Since you will probably not be making friends with these guys, I think I would also take out the K & N air filter so they can not use it as an excuse to explain the drivability issues.


Again, good luck. Let us know how things work out.

Had the reflash done. It raised the surging (1200 to 1700) rpm and made it worse to drive around town and the job site. Took it back (9 days total time in shop), they tore it apart, replaced all kinds of expensive parts, all with the help of GM TAC. After all that, GM said stop work, software problem, no cure at this time. During the visits, the techs working on it, put a deep 9 in. scratch on the hood, washed off the wax on the frame,both sides, checking the injectors, did not replace things properly under the hood (parts rubbing, tie wraps not replaced, etc.), dented the drivers door on the hoist post, and poured some kind of acid on the passenger door (ate through the paint). Of course, the dealer will repair, when I feel like losing my truck for a few days again. I complained to GM about buying a truck they copuld not fix and they basically said tough bananas (very politely though). One good thing is I do not get surveys any more. So, maybe the dealers you are visiting, are doing you a favour and saving themselves some money. Geo 2004.5 Chev CCLBLT 4x4

-:t I would not advise anyone to go to your dealer.. -:t

BH in AZ, thanks for the info. I planned on removing the Edge in the next few days after I finish a mileage test. I will also remove the K&N like you say. I have already been given problems just by having the 265's on my truck which has nothing to do with the issues I took it in for, but they surely look at that stuff.

when I went to the dealers I only told them that I had started seeing white smoke while idling at a light, then noticed a surging while cruising through a parking lot, and also started noticing the loud pinging on acceleration. Seeing as how this was the 4th dealer I had been to and he was in agreement with me and that they would check it out and all...what pissed me off was when he said the Diesel guy was out for 2 days after me telling him over the phone that I would be waiting there with my truck in plain sight. anyways....I will call him again and try and get down there. Its 30 miles, but as long as they do it I will be happy.
thanks

Briano,

The notice (PIP3129) uses the term "fuel knock noise" in the problem description, so you may have a better chance of sucess using their wording rather than "pinging" to describe the problem. There are several postings of the notice, so a search should find it if you do not have a copy.

Please let us know if you get the upgrade this time, and if so, did it help the problem. Hopefully the diesel tech will be there this time!

I have already printed that notice out and all. I will make sure to use their lingo!

I'll let ya know, thanks

How can you tell what numbers you have or if your pcm is up to date?

Kendall69 ... It takes a GM Tech II scanner to read the information.

The last LLY's for the 2004.5 models came of the line the end of June, 1st part of July, 2004. The newest LLY reflash became available around 9/10/2004. If your 2004.5 LLY has not had a reflash since delivery, then you do not have the newest version of the code.

Hope that answers you question.

05 built prior to 9/10- bone stock except for 4" cat back - 4,000 mi. Pings badly under any acceleration (normal or heavy), best mileage is in 13's, with city about 10 to 11. Doesn't smoke, no power. Dealer says no reflash available.
Was going to put tow tune on it, but due to time constraints will wait until I return from Central America in the spring.
