The last email I got from MadsElectronics; it is all being taken care of by Smarty. They have given this priority now and it should be out soon. I have my standing order for one!

This was a new problem on me as well. This is my 3rd Dodge CTD. '03 Quad was first (best one yet), then the '06 Mega and now my new one. I picked this truck up last Friday from the custom shop where I had my framework done to stretch the bed into a long bed. Drove 70 miles home, truck sat 2 days while I did the other add-ons and when I drove it yesterday the 80% warning came on in the center display. Called the dealership and they say bring it tomorrow. Before I even got there, the 100% Full - See Dealer text popped in and the truck ran so rough I didn't think I was going to make it. They tell me that they have to do most of what has already been mentioned in this thread. Drill Turbo port, pull the Blu-Tek system apart and clean the entire thing from the turbo to the tailpipe including this ridiculous filter. They say that I should never see this problem again after the work is done. I don't necessarily buy that but I will give it a shot.

I went to the MadElectronics site where the Smarty still says coming soon, but there was not much more info on it as to what all it will do. Since you got an e-mail from them, I am wondering what exactly the unit will do to the system. Will it disable the DFP so it can be completely removed as ForcedInduction mentions in his post. Also if you know, does that affect anything else within the ECM that would make the truck not run as the dealers threaten if any mods are done.

Does anyone here driving a 6.7 have a recommendation for a power chip. I am looking primarily for fuel mileage. I have used Edge chips on both my previous trucks. The '03 made a huge difference in power and mileage. At 65 mph I could get 23.5 in my '03. The '06 was not quite as good. The power was not as noticable but the mileage avg was about 21 on the hwy. Just wondering if anyone is using Edge with good results like I have previously had or if there is a better product with this engine.

Smarty is going to have the same levels as the 5.9L.
For commuting I set my 99 RAM to 1/2 power. The fuel consumption is just unbeliveable. If I just go speed limit, I get 23 MPG!

I recommend you wait couple of more months till I test the Smarty on my 6.7L. I will let you know if it is as good as the ones for 5.9L.
I was told that it is going to be an outstanding package.

MRowsh, do you plan to cut all the DPF system loose when you get the new Smarty? That is my main interest so I can dual my truck out without all the BS that they have in there now and to hell with warranty. I talked to a dealer the other day and he said exactly what you did about the new version. If the hype is real, there should be no need for stacking either.

I got my truck back yesterday. They did the full cleanup process on the turbo, piping and actually completely changed the DPF. It was still laying on the ground in the shop when I got there. Also, the turbo tap didn't have to be done as my turbo already had the factory port on it. A new flash was also put in the computer to supposedly adjust regen time and temp of the EGT to prevent this from happening again. The day didn't stay all bright and cheery though. I live about 65 miles from my dealership. 15 miles down the road, I got engine light, 70%full. Within 2 sec, it said 80% full, and then immediately went to 100% full. I called the service guys and they said it may be trying to do another regen and to keep driving and let them know. The regen did start and it came back down to 70% full and then System OK appeared, although the check engine light didn't go off. I am thinking it is some sort of fluke that will clear up, but it just got worse. 25 miles later, the same process as above happened again, but this time it didn't try to regen, it just started de-rating power and the See Dealer, Filter is Full text came up. I also realized that in that 65 miles, I burned 1/4 tank of fuel. They sent a man to my town with a loaner truck and hauled mine back to the shop. They say they have never seen this happen after the clean-out. I am skeptical that there is some sort of computer malfunction either dumping way too much fuel to the filter for the regen or possible a bad sensor for the pressures they are measuring for differential pressure across the DPF making it think it is plugging up, then dumping fuel to regen and plugging up because of the rich burn. I don't know and at this point neither does the dealership. At least they are a good bunch of folks or I would be postal over this.

Has anyone seen, had or even heard of what is happening with my truck?

Thanks

Sounds like your engine isn't running right and is dumping lots of fuel/smoke into the DPF. They should drive it a few miles without the DPF and see how much the engine smokes on its own.

Shyjack; The Smarty suppose to take care of everything for us. There is no need to get ride of all the BS exhaust system. The trick is to run the engine hot enough to burn everything. So, we are not gong to have any problems with State's inspection of not having the DPF on the truck. It is clear that if we take all the BS off of the truck, it will not only run much better, but also the fuel consumption will be exertimly improved. But then depending on your State's regulations, you might run into problem. So, with Smarty the removal of all the crapy exhaust additions will not be needed!

The existing problem is that; in order for the existing system to clean itself and stays clean; we have to run it about 45 minutes with RPM above 2200. The temperature in DPF has to get as high as 1500 in order the NOx and DPF gets cleaned out. The first big cone shape after the turbo is the NOx cleaning system, and the second big one before the muffler is the DPF. With The Smarty doftware installed, number one, the EGR not going to get into the intake, and also the injector's timing will be adjusted accordingly in order to burn all the fuel, and keep temp up, but in the safe zone.

Ofcourse I have to see it myself in order to belive it! As of now, I am trying to run my RPM high enough in haighway driving (put the shifter to 5th gear at 75 MPH, with auto trany) so it stays clean for time being till I get my hands on Smarty.

One option is to hollow them out and slide a straight pipe inside them like a roll pin. You don't want to just hollow them out or they will become expansion chambers and it will be two steps forward and one step back.

If you have to pass the inspection in your State, that is not recommended. Because when they connect to the trucks ECM, they will see the code!

With the Smarty, you can return the ECM to the factory setting, go get inspection taking care of, then reprogram your ECM.

The other option is, to drop your entire exhaust and save it in your garage. Replace with high perfoormance exhaust system. When inspection time comes around, replace it with the factory and you are ready to pass the inspection.
After testing Smarty, if I see that there is a need; This is what I am going to do. Few hours of labor to replace it back and forth, but I think it is worth doing it.

If the Smarty turns off the regeneration and DPF checking functions, the ECM shouldn't be setting any codes with the filter disabled/removed. The only sign would be smoke out the exhaust.

Yes, it will turn those damn things off. BUT; For inspection due to the fact that they will connect their diagnostics computer to your ODB II socket and read the ECM, you have to reinstall the original ECM software. Therefore, there will be a CODE present and ready for inspector to read if you have bypassed the NOx and/or the DPF exhaust sections.

When you have the Smarty loaded, you will also have two codes present, which is part of the Smarty software. So, it does not matter what you do, there will be a code. But you will not be able to pass the inspection with the Smarty loaded into the ECM. And if your State does not require Diesel inspection, then you have nothing to worry about.
