The 06' Difference?

What's so different about the 06' Dodge compared to the 05, 04 & 03? :confused:
 
I think (but not sure) that it is a hybrid between the fully environmental '07 and the powered 610 version. Not sure I'd touch one though. I'd let the dust settle on this stuff first. If I was buying a used 3rd gen I'd lean towards an early '05. The '03's had something like 47 different software versions and a mix and match set of parts from the second gen's through. I see the same happening with the first '07's as well. Give it at least 1 full model year to get the software and the motor sorted out. JMHO...
 
I'm guessing the softwear break must be on 6/6 of this year? I remember something about the SMARTY not working with build dates past that point. I wonder if a re-flash would flip ya past that point?


I was curious as to the physical changes. I can see the computer is angled and that the turbo seems to have a large amount of meat behind it...but what of the valves and stuff you can't really see?:confused:
 
I have a 06/06 and the truck is basically the same as a 05. The big differance is in the ECM. They added programming to allow an exhaust brake. I just added a ground signal to the ecm to enable the exhuast brake and it puts the trans into a tow haul mode that accually down shifts the trans from OD to 3rd. The ECM burps the throttle during the down shift to ease the strain on the drivetrain. There are other small changes but none that are signifigant.

Just bought an '06 built just short of the June cut off. The MAJOR issue is the pressure in the rail. My understanding is they lowered rail pressures to avoid cracking injectors from '06.5 on, among other ECM changes. The '07s are the nono so far. I just wanted to get in before there were no more '06s left.:ylsuper: Internally I'm going to say the motors are the same.....
 
So, we have weak injectors? .....that doesn't make any damm sense.

The '06.5 rail pressures are less than the '06 and older, to avoid cracking.
Get it?
 
We need rail psi to keep the events clean. Lower the rail and you Slow Down, Loose HP and Loose MPG.....not good.
 
Lowering the rail pressure shouldn't do anything except increase the life of your CP3 and your injectors themselves. Yes, you would loose HP but...

Increasing rail pressures, increases the likelihood of premature failures in the injection system.

Which is why you want an '06 and not an '06.5.......

I agree, lower the HP on almost any engine and you will extend it's life ...or it should. However, how is it possible to lower the rail and still attain the current HP & TQ levels? Also, why would Dodge want to lower the PSI while the others are increasing it? Sounds to me like Dodge skimped out somewhere along the lines. (no pun intended) Maybe this is their idea of raising MPG or something? I know the fellas that tow in OEM dress will be mighty upset.

I'm of the understanding that the GMC DMAX has the lowest rail pressure and hence the reason why few CP3 failures and rail problems. Maybe I'm wrong but this is how it was presented to me.

Also need to consider that the I6 has the most available (usable) Torque where the others have high HP etc. If you are a RV'er you'll want the low end vs. the highend.

I only know of one guy that has successfully hacked the system and removed injection events and lowered the rail pressure. He has no warranty and doesn't really care but has a good truck. I'm no where near that good with computers.
 
You know....I didn't think about it that way? If you lower the fuel all ya haft'a do is release more off the TQ management system. The Cummins is cut wayyyyyy back under 2000 RPM. However, between 1,700 and 2,300 RPM is where you need fuel while pulling. I don't see how cutting back fuel could save you time? Would it not just slow the truck down? If you slow down it drops a gear (3rd) and you could burn MORE fuel than you would with high rail pressure and low RPM (4th)....right? And yes, I'd like to be much better with computers as well.
 
Remember the Diesel Power "contest".. I wonder how the Dmax fellas attained higher MPG with their trucks? I belive Nick won. He had to have the best of both worlds, hp & fuel economy, to win the event. How did he do that with a 4x4?
 
If the rail pressure is lowered, then the HP is gained through timing and duration, which is the proper, and safe way, to add power.
 
Is it true then an '06 purchased in November '05 is the same as an 05' then?

The smarty works on ALL 06's the 06/06 has nothing to do with smarty.

Thanks
