Recall VB6 - 2019 DJ D2 Diesel Engine Calibration

Recall done last Friday and first impressions unloaded and loaded completed today. 625 miles unloaded with cross headwinds for about 300 miles averaged the same MPG as before. Delivered 14,700 lbs Jayco North Point 412 miles today. Light wind with average temperature of 33 , MPG about the same as before. The noticeable difference was how the transmission shifted up and down. It doesn’t bang shift anymore and it locks the TC quicker during shifts. With EB set on auto, it was not as aggressive to slowdown when lifting the accelerator until you hit the brakes. Nicely done update and one of the first that was not a letdown. Updates on my 03, 09, 12 and 16 never seemed to work to my advantage, same complaints as everyone else had. Reduce power to compensate for something else. 42,000 miles since January 10th and this truck just keeps making me smile.


What truck do you have? HO or SO?
 
PD Diesel said the new update has him loving his truck again. He works em too.

He hasn't said which update it was, though, VB6 or a prior update. I asked, but he hasn't answered yet. Interested to know.
 
I saw that comment!! I did notice he didn’t say which one.

With how fast he throws out impromptu videos (which I enjoy by the way) I assumed it was the latest ECM TCM updates.

Do you have the paperwork the dealer gave you? It should show the firmware version installed after the update. It would be good to confirm you have 52401932AH because maybe you have an even newer version (like 52401932AI) that runs rough like 52401932AG.

So I got my truck back today (2019 Ram 2500 6.7L) for recalls W03, VB6 and W33 recalls. Immediately noticed on the way home that my trucks shakes at idle. I thought it was due to being cold and my truck hadn't warmed up. However still noticed it after 30 minute drive and came here to see if others had similar experience after updates. Seems confirmed however, my ECU part number isn't the same as what you all are reporting. It shows up as 52370931AI. Specifically they state: "Successfully flashed ECU from old part number 52370931AF to current part number 52370931AI". I'm absolutely experiencing what I would consider rough idle. Not sure but the RPM's it idles at seem lower to me. I can feel the whole cab shimmy now.
 
You're not alone @IronByron, I am experiencing the exact same cab "rocking" like a very slightly out of balance/engine at idle. It is not rhythmic, but instead erratic, and smooths out with high idle. I noticed it immediately after the same recalls you did. I had my truck in the service dept this morning hoping to find out that i had an old version of the software and an update would be available. But was instead told by my ram service department that i have the latest software (52370931AI) with no update available. My recepit from the service department says they couldn't duplicated my issue (not surprised). I have also already brought this up to @RamCares the same morning my original recall was performed. Looks like we're all just out of luck until Ram comes up with an update.........my truck is under 5,000 miles. My confidence in ram, and respect for the brand is getting chopped away consistently with these petty issues.
 
I was basically told the same thing by my dealer after updated to the AG calibration with rough idle etc in my HO truck. Took it back and they agreed that it was rougher than should expect so they contacted FCA and were going to get back to me with a answer. That was about a month and a half ago. I got the vb6 notification the day after that and asked if the vb6 was what they had updated my truck to and they pulled it up in the system and told me it is what they already updated my truck to. After further investigating I found that they didn't update my truck to the vb6 update AH calibration. Mine was updated to the AG calibration and others had the same complaint and claimed the vb6 AH calibration fixed theirs. So I eventually got my truck back into the dealer this week and got the actual vb6 AH calibration flashed in and the truck is much better now. It's definitely irritating that the dealership are too lazy to actually seek out proper information and then get back to us once there is a possible fix. I had to do all of the research and spoon feed it to them in order to get anything done.
 
I know generally most things can't be flashed downlevel (I'm in enterprise IT FWIW). Is it possible for the dealer to flash a specific (going forward) version or are they forced to flash the latest?

I know there are some TSB's that are optional, like my 04.5 still has a few open recalls including the airbag one, but I will throttle the dealer if they install that stupid reverse horn alarm TSB when told they are not to under any circumstances.

I can't stand to watch his vids, 99% rambling chit chat and 1% to the damn point.

Irritating.

Like trying to read through and track a technical thread with chit chat and off topic car wash pics.

I need to find out how to get him out of my recommended viewing list.

@IronByron, I was worried that version AI+ might reintroduce the rough idle that seems to be fixed in AH.

My truck ran acceptably on version EF. It ran very rough on version EG (just like you describe with AI). It runs fantastic on version AH. I do not plan on updating the truck unless it refuses to start, because right now it runs perfectly.

As @brutal pointed out, the dealer probably will not (or can't) downgrade from version AI to version AH for you to test or demonstrate to them the problem.

I suspect your best option is to go back to the dealer to open a case and work with RAM Cares to get it converted to a star case.
 
How come some are reporting their ECM version at 52401932AI and mine is 52370931AI? Mine seems to be much lower version in regards to the number portion (excluding the last two characters).

Also note that my previous rpm at idle seemed closer to 1000 rpm, maybe in the 900 range. Now it appears to be 750 and close to 500 at times. The rough idle shake I feel in the cab seems like it's almost going to stall out, or at least the sensation feels like that.
 
Actually, I’m wrong about the RPM’s post update. I checked my iDash logs before and after (not sure why I didn’t think of that before complaining) and they seem to be about the same, if they are lower it’s only like 50 rpm’s. I would have to go through several instances of log data to know exact details. Regardless still there is definitely a rougher idle now.

The reason your version is slightly different is because your truck is a 2500 and my truck is a 3500.

In this document, you can see that 52401932 is for the "2019 D2 6.7L PCM AISIN 50 STATE D2 - RAM 3500 PICKUP"
In the same document, you can see that 52370931 is for the "2019 DJ 6.7L PCM 68RFE 50 STATE DJ - RAM 2500 PICKUP"

So, in Ram's numbering scheme, the first part of the firmware version represents the vehicle type, and the last part (AG, AH, AI) represents the firmware build number.
 
I just drove our 2019 HO truck. It now has the VB6 calibration ending in AH and the transmission tsb 21-001-20 calibration 68475153AD. The cold start is much better now but still a little rougher than I remember with the calibration AF. I noticed when driving it seems more crisp and responsive. But under certain moderate acceleration like 6th gear 50mph and about half throttle acceleration to 65mph it seems to have a surge. I watched the boost gauge and you can see it oscillate by about 3-4psi when it's doing it. I'm not sure if it's boost or possibly fuel related but to me it feels like it's bumping some sort of soft limiter in the tuning parameters and pulls power back a little and gives it power back again over and over. If I had a good long hill to keep it in that range or a loaded dyno would be perfect it would be easier to determine what's happening. But just driving in that range it does it like 3-4 times and then I'm speeding and let off. It seems to do it in other acceleration speeds too but it goes thru those ranges faster and it's harder to notice.

My truck has the exact same combination: PCM version AH, and TCM version AD. I really like this combination of PCM and TCM, but I do agree the idle does seem slightly rougher than I remember with the AF calibration. I haven't noticed the PSI oscillating like you describe, but someone else reported this behavior as well.

I recently bought a Banks iDash DataMonster. I will go for a drive and get some data logs to see if the PSI oscillates.

I have held off this far as far as tuning and data logging. I didn't realize banks idash data monster was compatible with our trucks. I have and tune with efilive, HPTuners and Warp/ MM3 platforms. I've not kept up with efilive progress with the 2019 trucks and the data logging abilities but in the past the good data logging came with requirement to tune and upgrade operating systems to take advantage of Enhanced EDA logging capability.

The iDash currently doesn't have a custom profile for the 2019/2020 6.7L SO/HO diesel, but nonetheless it can log about 100 parameters. For example, it doesn't log the gear my Aisin transmission is in, but it does log EGT, coolant temp, boost, speed, and a lot more.
