- Cummins12V98Explorer IIIThat's impressive!
- I remember a while back a GM engineer went on record saying there's was no TQ management about the same time the 10 speed transmission was released.

My source was GM. I forget exactly when/where/how. I can tell you that the TQ managment was noticeable in my 2001 and 2011. Not at all in my 2020. Turn the traction control off and it's like driving my camaro:B
NOT calling you a liar but can you prove this???

They all have power management systems. It keeps warranty claims down. You just do not hear of motors gernading anymore. Having said that, GM for one has worked hard to keep it's Dmax out of power management range. Gale banks had a video about all of the cooling upgrades they did so that the Dmax can provide full power at all times. This is my third one, and though the first two had no cooling issues, the latest one takes it to another level. I am in Phoenix AZ, and tow pretty heavy. It just doesn't even think about getting hot. The first two did limit power in first gear to protect the rear axle. With the new 10 speed, they were able to use a taller (stronger) gearset in the rear axle. They also increased the size of the ring gear. The result is that torque managament in first gear is no longer needed.4x4ord wrote:

The fact that under load the Duramax was faster 0-60 than the PS. I actually expected the DMax to be faster empty. It clearly was not. I guess one can assume that the PS is managed under load and less so running empty. The DMax must have less management all the way around, but left to the numbers, the PS's additional HP, left unmanaged, is more than the DMax can match.
From a GM perspective, if your coming in statistically that much lower than the PS, you better turn it loose to compete. If your looking for a reason to find this interesting, this video shows that driving either one of these pickups as a daily, it will perform empty very much like a high hp gas 1500/150, the PS even more so.
What exactly are you thinking torque management is? I doubt very much that the Ford's poor performance on the hill has anything to do with torque management. That said, I have no idea why it performed so poorly. I know that my '21 Powerstroke got better fuel economy than my '22 Powerstroke does... both trucks were spec'ed identical. My brother's '22 (spec'd identical to my '22) gets similar mileage to what my '21 got. Maybe there are slight differences that make one engine more efficient or more powerful than another?
I think torque management is the pickup depowering itself to stop from damaging itself. It could be just differences in pickups. I don't know obviously what the exact cause is, it just seems when these trucks now know when their overloaded that it would be easy to manage the torque depending on the weight they are pulling. With the power that the Ford has, maybe they try to protect the pickup when pulling that much weight from aggressive starts. With the pickup unloaded, they allow it to run more aggressively. The Ford pickup in the drag race decisively was faster than the DMax, seems more than just a difference in one pickup to another. GM was infamous for a while for "dead pedal", a form of torque management. That went away when the trucks were able to tow more weight. Perhaps Ford is doing something similar. Going up the IKE, the Ford should have owned that run, and while it was the fastest, it should have been much faster as you pointed out. As I stated before, given how warm the Ford got, I am left to believe they manage the power when pulling heavy. ShinerBock wrote:
And this is one of the reasons why I kept away from this forum. Too much brand bashing and my favorite brand is better than your favorite brand instead of just enjoying what we have. I understand why it happens and why people do it, but I'd rather just stay away from it.
Just checked in after six months only to see nothing has changed. See ya'll in another six. Hopefully this forum will get past this by then.
Prost, everybody!
Hey... Prost to you too! :C- Grit_dogNavigator

Sup shiner?
Me and 12V are gettin our a$$es handed to us by all the Flowerjoke drivers lately!
Need you back! Lol.
Take care man. Hope alls well. - Cummins12V98Explorer IIIYEP, it's the one that gets you there every time!!!
- goducks10ExplorerTowed home from a CG today. 170 miles worth. Wouldn't of mattered if I had a 6.0 gas or a 6.7 PS. Traffic was thick with slow going semis and motorhome scenery gawkers. Not sure even a new ZO6 would've been much help.
FWIW I didn't watch the video. - ShinerBockExplorerAnd this is one of the reasons why I kept away from this forum.
