08 dually Auto, STOCK everything, no intake mods, no exhaust mods, STOCK. Drove it over 20000 km, (12000 miles for my southern friends), before 67 was available, I pull a 15000 lb race trailer nearly half my miles, sometimes pull a 4500 lb boat and the rest of my miles are empty usually at 80 mph. I pull the big trailer between 65 and 75 mph, sometimes faster, the boat slower because where we go is over a long mountain pass. When I installed Smarty I drilled the manifold behind the turbo, installed a probe and run a analog pyro guage. Stock empty this truck hand calc'd 16 mpg at 75 to 80 mph. With the 15000 lb trailer averaged 9 to 10 and always felt like it was working hard. After Smarty install I picked up 1 to 2 mpg and if I want to go faster I just step harder on the pedal, I made 1 trip at the 30 hp setting, pyro temps never came above 700 so I moved it to the 60 hp setting and have run 10000 km's absolutely trouble free. The power is AMAZING, pyro never above 900 except when it regen's, I've seen this only twice, and it went to about a 1000 On long grades I pass anything I want to, pedal to the metal and NEVER worry about anything. My warranty was important to me so I didnt want to delete the dpf or do any of the other warranty unfriendly things, so my experiment has been to remain stock. In ten thousand k's I have not had 1 code, I do not idle this thing except for cool down. Happy? You bet, now that I have publicly extolled the virtues of this thing it will probly blow up next trip.

 

Sounds good. I haven't got quite the Km's on mine yet, but the upsides of having the Smarty and being able to upgrade with the software releases appeals to me. I plan to do the DPF elimination, but it will be neatly stowed for the future if need be. The MPG gain from that alone has made the decision for me.

The pyro after the turbo isn't the whole story. Pre-turbo, the EGT's have been as high as 1400°F during re-gens but only around 1200 loaded.

I also run SW3 but have toyed with the VGT setting a bit just for fun.

That is exactly the same thing we are doing. We left everything on the 09 trucks and just use the software.

No problems with anything, no excessive additional bills for parts, to replace new parts on new vechicles.

 

Are you saying that a Smarty is still a good idea for a stock truck?

For certain!!! I wouldn't run without it..

 

That's what I'm saying!! Re-read my post.

 

How is the tranny holding up? Has anyone taken theirs in to get the bands adjusted, filters changed, etc? I've only had mine for 3 weeks and I think that tranny is the best thing since sliced bread...

 

Just a heads up - 3 weeks ago I would have agreed with this statement:
"On long grades I pass anything I want to, pedal to the metal and NEVER worry about anything"

FWIW I just returned from a 9800 mile trip. On the return 90 degree day ran into some stop & go traffic in the Seattle area - much further South pulled some grades & passed a few other rigs. Per the stock gauges the water temps never got past the second 0 of the 200 (looks to be 210 or 220) and the Isspro trans temp never got over 210 (note probe is in the large +4qt PML trans pan not the hot line). When I stopped for fuel the coolant recovery bottle was full and dried "pink" coolant was all over the left side of the engine. After everything had cooled down I added a little over a gallon of coolant. Note I had to go to a dealership to get the correct coolant.

When I got home I took it to Dodge and everything checks out: fan works, pressure test cap & cooling system, block test, no exhaust gas in the coolant etc. However codes confirmed that at some point the coolant had overheated and the trans temp had exceeded 250. Changed out fluids, radiator cap and thermostat.

Background:
Truck has 42k on it
1st trip towing the 5th wheel (12,500 lbs) with the Smarty which was set on #1 30 hp.

3rd summer with the same 5th wheel
last two summer trips were in the 6000 mile range but in an area that had steeper mountains, longer grades and hotter weather, & I had pushed the truck just as hard without incident.

Going forward:
I will probably pass fewer rigs on hills and am thinking about moving the trans temp probe to the hot line and getting an aftermarket water temp gauge.

PS my 07 manual states the coolant capacity for the 5.9 is 28qts vs 22.8 for the 6.7

 

I think alot of the heating issue lies in the EGR cooler.. If the pan temp was never over 200°F in the tranny, I don't see how it could have overheated. When the truck is in TC Lockup at highway speed, its running cool. Stop and go with lots of slippage, thats the killer.

 

Personally I would want a Blackstone report after overheating any engine.

1 - Highest trans pan temp was 210 per Isspro gauge - Diesel tech said code was set that indicated trans fluid had hit 250. He also said the fluid looked good and didn't appear as if it had overheated. "Stop and go with lots of slippage, thats the killer" I agree thats when I saw the high temp.

2 - Tech also mentioned EGR cooler as a source for heat.

Please elaborate on a Blackstone report.

Thanks

 

Blackstone labs is just one of the many company's that do oil sample analysis. I would want to have a oil analysis done for personal record.
Things like a scuffed wall will show up even though the engine runs fine and if it comes back in the normal wear range then at least I could put to rest any concerns I had.
Typically EOA are used to track wear but they also will show problems in the early stages if you want to know if you hurt something. You would need to have the oil in question still in the engine though.

 

x-rated,

you said you were concerned about your warranty so didn't do the dpf or egr mods. you have a s67 though - i thought it was traceable at the dealerships . . .



lil dog,

what kind of mpg gains will you see with the dpf & egr mods?
won't the techs be able to see wrench/tamper marks on the dpf hardware if you remove it and replace it before going into the dealer?

 

I am not looking to pull the wool over here. I expect to be traceable even as I run now. But a good 4-5 mpg improvement from dropping that heavy junk off the pipes is reason enough for me. Honestly I don't know what they would have to warranty after I get rid of that stuff engine wise. If they can fix a window that doesn't work or the rest, thats all I can care about.

 

I was at my dealer one day this spring and noticed a guy walking around the trucks in the lot where they wait for service, he crawled under a few and looked under the hood of the ones that were unlocked. I asked my sales guy *** he was doing and he said he was a warranty audit guy. If he saw trucks with DPF delete or other noticeable mods he would flag them with Chrysler Canada and would void the warranty's. Could be a load of crap but at this point in my life I am unwilling to take the risk.
