DT Acceleration Slow Compared to DS

[BrandonSmith]

I recently 'upgraded' from a 2017 Lone Star to a 2023. Same specs, except the 2023 has eTorque. I noticed the foot to the floor acceleration of the '23 is much slower than the '17. What gives?

How long have you been driving it? It "learns" as you drive to adjust the pedal acceleration. But even then, it still a little sluggish to me. But my Pulsar wakes it up. Pedal Commander and the like will do a similar (not same) job.

4 months, 11k miles.

I have heard this a few times now. Can you expand on how the 5th Gen’s “learn” as you drive, or steer me in the right direction? Pun intended.

I’m coming from a ‘15 DS and just chalked the DT up to being a new truck.

The electronic committee all has to agree on the same thing and that rarely happens if you mash the pedal. You can fool them by using 2/3rd throttle then full throttle once you hit ~4K rpm

I believe the DT's are also over 1,000lbs heavier, aren't they?

The PCMs have had adaptives since OBD2 came around in 1996. It's nothing new. The adaptives changing over time are what people mean when they say it's "learning". Fuel, timing, shift points and shift firmness will all adjust over time based on your driving style. Will also add in throttle response. Should only take a few hundred miles to maybe 1000 miles. This is why your vehicle always feels a little more "peppy" after exiting the freeway from a long drive at sustained highway speeds. And also the main reason people claim they have better throttle response after adding a CAI or exhaust because they unhooked the battery and cleared the "learned" adaptive. Because neither of those kids will have any effect on throttle response by themselves.

Actually a couple hundred pounds lighter due to things like Aluminum hood and tailgate

No. 5th Gen is lighter

Ram unveils redesigned 2019 1500 trucks with new look, less weight, more tech

It’s only January and it looks like Ram has already tackled some new year’s resolutions. The 2019 Ram 1500 has checked off an impressive list including cutting weight, getting a stronger frame, adding more driver-friendly tech and introducing eTorque, a mild hybrid option that will deliver more...

I’m talking more about passing on highways more so than 0-60. Throttle response is not the issue. It downshifts quickly once my foot hits the floor.

It is noticeably slower. After the downshift, 50-70 takes forever compared to my 2017.

As far as weight, my DT is 200# lighter than the DS. I tow a travel trailer occasionally and weigh the truck (with me in it and a full tank of fuel), then the truck and trailer, then the truck and trailer with weight distribution hitch. From my trips to the scales I know the DT is roughly 6100# vs the 6300# DS.

What's the gearing of the 2 trucks?

 

[theblet]

what’s the rear end ratio?

3.21 on both

Yeah that doesn’t sound right. Mine screams from 50-70 mph when passing. No issues there at all.

Yeah, that doesn't sound right. Maybe a dealer road test is in order.

I drive with a fairly light foot for fuel mileage most of the time, but if I push it 1/3 - 1/2 down to merge or pass, it drops down a few gears and takes off. If I floor it along the on-ramp, it'll briefly light up the tires and take off like a scared rabbit. My wife isn't a fan of me doing that as she's used to quiet engines and exhaust notes, so when the Hemi growls, her eyes widen with concern.

I rode sport bikes with Yosh pipes for years, so this kind of behaviour is familiar to me.

My son has a DS 3.21 hemi, and it seems his is faster, because it spends far, far less time in torque management than mine, however you both have the same gear, so...

The "learn" might be "adjusted" by a few WOT bursts before you actually race someone; it is on my cheby, monitored by hptuners.

Disconnect your battery for 30 minutes then drive it like you stole it and test it on the highway.

I recently traded my 2017 Laramie for a 2023 Limited and the 23 is considerably slower accelerating. Still acceptable, but noticeably slower compared to my 2012 and 2017 Rams. Reminds me of my 03 when the Hemi was rated at 360 HP.

 

[theblet]

This is my first ram so I can’t compare to another one. Mine will hit 100mph from 55 quickly when I pass someone. Also chirps the tires good when flooring from a dead stop. No complaints besides throttle lag, but I’m used to that now

Proof?
What do you determine to be slow?
I consistently do 5.9 seconds 0-60 on an 6300 lbs truck. I don't think it's slow.
