New RRT for latest flash

[Jeepstang]

Does it feel like the exhaust brake is slightly on all the time?

Now I have a general question?
I took my truck into the dealer today for the reflash.
I observe zero difference in operation!
The Software Update Tag under the hood still reads 55351105 AT not 55350235 AU as I would have expected.
With the AU update should the Software Tag not reflect this change?

Yes it should have been changed. I didn't really notice a difference, they may have just forgot to update the tag. Give them a call.

The tag is a legal issue it should be dated along with all the other blanks filled in.

The tech working on your truck may not understand the whole process,and just performed the tsb which is NOT the same as the RRT.

Unfortunately the industry is doing nothing to attract competent help or to retain the good techs it has. Good luck with your dealer,I know it is tough when it's a work rig.

I took my first trip approx 320 Km, since the reflash.
EGT - 960 degrees - on the flat @ 100 KPH/60MPH
EGT - 1260 - 1320 degrees - on the flat @ 100 KPH/60MPH One Regen cycle which lasted 18 Minutes
Boost 5. 0 lbs on the flat @ 100 KPH/60MPH
Boost 5. 0 lbs on the flat @ 100 KPH/60MPH One Regen cycle which lasted 18 Minutes
The Exhaust Break appears to be a little more aggressive, which is a good thing.
Fuel Efficiency is a tiny bit improved
So it would appear some progress has been achieved however the EGT is still running 260 degrees hotter than the reported average on the TDR.
This is still of concern to me as this speaks to a shortened life of the Pistons, Valves and Turbo
I am surprised with the increased in running boost pressure.

The EGTs you are experiencing are very safe

I too would like to see corporate Dodge or Cummins communicate a little more with us owners but having sat on the sidelines and watched just one small element of the issue I understand completely why they don't and I would not either if I were a corporate decision maker.

In summer of 2002 I attended the big TDR rally to celebrate the introduction of one million Cummins engines installed in Dodge Rams, the new HPCR engine, and the new Gen III Rams. We were hosted by Cummin at Columbus, IN and treated like VIPS. It was an extremely interesting and enjoyable week.

The corporate communications element I speak of was regarding the Jacobs Exhaust Brake. Jacobs engineers who are part of corporate Cummins, Inc. told the group during one of the briefings that they hoped to be able to announce and authorize installation of Jacobs Exhaust Brakes on 48RE equipped 2003 Rams soon.

Carlton Bale, a Jacobs engineer was apparently assigned to communicate with TDR members or perhaps did it out of his own good will. Over the next two or three years he posted occasionally on TDR and answered member questions regarding their testing, development, and, eventually, authorization of an exhaust brake on automatic transmission Rams. Some of you will remember and all the old threads and posts are in the archives.

In summary, the engineers learned first that the ECM of '03 and then '04 Rams lacked sufficient memory capacity to hold the programming they considered necessary to actuate the exhaust brake integrated with the Tow Haul mode. Then they learned the '05 Ram had sufficient memory capacity but the 48RE had a reverse thrust bearing that couldn't stand up to continual hard deceleration under load with an exhaust brake. Finally, for model year '06 Dodge-Cummins authorized exhaust brakes on the 48RE and offered it as a line item when the trucks went on sale. I bought one.

(Development was more challenging than some might realize because their goal was to program the computer to activate the exhaust brake in "OD" and commence slowing, then deactivate the brake momentarily, downshift the automatic to "Drive", the reactivate the eb", then do it again down to second gear as speed dropped off)

My point is after Jacobs engineers announced in 2002 that they were working on it some members interpreted their words as it WOULD happen in a few weeks and beat up on Carltoni Bale on the TDR forums demanding to know why it hadn't happened, when it would, and one or two blamed Jacobs or Cummins because they (the member) had bought an '03, '04, or '05 automatic and couldn't use a factory exhaust brake. I think one or two even said Jacobs/Cummins should have to retrofit their trucks or buy their truck back so they could get another new one with an EB.

I felt sorry for Carlton as I read the long-running thread. He was the designated scapegoat and had to walk a delicate line trying to keep us informed, deal with the anger expressed by several, and avoid putting his company on the hotseat, perhaps even jeopardizing his job. It was sad because they were doing their best to develop and integrate the systems so they could sell their product. All of the trouble stemmed from them telling us they were trying to develop an EB that could be installed on automatic transmission trucks.

The moral of the story that I'm sure Jacobs engineers and perhaps Cummins learned from that experience is "don't tell consumers anything until it is set in concrete and will never have to be modified, altered, 'reflashed', etc. "

DC released a new RRT yesterday that advises dealers to reflash ALL trucks before sale to the AU level software. So if you have yet to purchase, make sure the dealer performed the RRT and you will minimize the chances of a regeneration or turbo problem. And as I have said several times, if your truck has not been flashed in the last few weeks, you are probably best to get in and have it flashed. Doing so will ensure you have the latest changes just like unsold trucks.

Should this be don on 09's?
