What did they change with the programming for the Aisin or what have you noticed?I haven't had a chance to pull with mine yet. It is unbelievably quiet inside. Yes, I do have concerns with the CP4, roller-hydrailic lifters, hollow cam, scissor gear, etc. Time will tell on that stuff. I went '19 because I wanted the power spot mirrors, cameras, and the 12" Etch A Sketch. 1K ft/lbs might have been a factorThey do seem to have outsmarted themselves with the new programming for the Aisin, but I am hoping for a reflash at some point. It's much too soon for me to give much of an opinion, but I am sure enjoying having torque by the cubic yard again.
So far, the only thing I noticed is when I roll onto my driveway from the lane I share with my neighbors, there is a 90 degree right, followed by a short downhill I coast down, it will be in second as I roll onto the uphill approaching the house, and it will actually feel like it goes into a false neutral(RPMs climb)before slamming, and I do mean SLAMMING,into low. My buddy has a 3500 SRW, and has experienced this even with a horse trailer hooked up. He, and others, have also complained of radical, unnecessary downshifts when decelerating even when not in T/H and with EB off. He is actually pretty disgusted at this point.What did they change with the programming for the Aisin or what have you noticed?

People that went to the rally had the fortune of speaking with a handful of the lead engineers on this new engine. One of the gentleman was involved with the durability testing of the new engine. The actual tour was time Limited, but fortunately he happened to be at the pavilion at Ceraland the following evening after the drag race at Indy. We shot the breeze over a few beers and I was fortunate enough to pick his mind over the new engine. I can tell you he was quite excited over the new platform - particularly the roller valvetrain. In his words, way over due. Said the cam gear was nothing to lose sleep over, no failures in all of their testing. The only thing he had pause for was the CP4 and he went on to say that while it is NOT the same pump used in other applications that have had problems stay tuned for improvements.
Wouldn't elaborate beyond that.
Interesting comment about the CP4.2 pump. I was under the impression that just one CP4.2 pump was available from Bosch. I contacted Cummins and asked if any changes or upgrades had been made to the pump supplied for the Rams, and they said I would need to contact Fiat/Chrysler for any information on the CP4.2. They tried to imply that they had no information on the pump specifics. Corporate buck passing at its finest!
I cancelled my 2019 order when I looked at the internal design of the CP4.2. No mechanical indexing of the lifters in their bores was a deal breaker for me. That design is just baffling.
I brought my '16 into the dealer for some recalls a few weeks back, instead of the normal Hertz Rental car, one of the sales guys gave me a '19 2500 Cummins 4x4 short bed to drive. Mine's a long bed so of course this one was easier to park. In general nothing stood out as being too much different that would make me want to trade up, EXCEPT... the transmission gear shift buttons were no longer on the shift lever but on the right side of the steering wheel. It was labeled something to the effect of Gear limiter. I don't exactly remember. Just that simple change is almost enough to consider a trade. RAM engineers, if you're listening... MOVE THE EXHAUST BRAKE CONTROL BUTTON!!!! It's so inconvenient to have to reach down to the current location, especially if you have a center front seat passenger. If it were too on the wheel above the cruise control panel, that would be excellent, not to mention safer.
Agreed, I think the tow haul at the end of the shifter handle and the ex brake buttons on the wheel would be great.I would like to see the Tow/Haul back on the end of the shift lever, and the Ex Brake in the lower left quadrant of the wheel, arranged just like the shift buttons, one for On/Off, and the other for Full/Auto. I saw some Paccar trucks with the Jake buttons on the wheel like that. I hate fumbling around on the center stack.
