Poll- Do you like MDS?

[retired]

I can tell zero difference whether or not it is kicked in. I do know i get great mpg on my 6.4 so maybe it is working. Just drove from missoula to boise yesterday and hand figured 16.8mpg

Kinda like the start stop lol

You inciting another tirade from me, Treb?
Lol

Thanks to Corey's research we know even though they shut down 4 cylinders, they also send twice the gas to the working cylinders, no kidding. I would like to see more guys actual test actual mileage, not what evic says, on both trips, one with mds on and one with it off.

I keep meaning to get a video of that. You can literally watch the the non mds cylinders double the injector PW when MDS activates.

It also seems logical that the system creates uneven wear between the MDS and non MDS cylinders...

Ford is definitely not "back to regular V8's" in any sense other than continuing to offer the same 5.0L they have had for eons.

It's been updated for 2021(?), it now puts out 5 more HP than my hemi does, and the same amount of torque, even while being short .7 liters.

Reviewers have found it to be faster than our 1500's, which is not surprising since the truck is 100's of pounds lighter but putting down the same power. Ram needs to up their game!

The Coyote is a solid motor, no doubt, and Ford keeps doing tweaks to keep it relevant and selling. Which is good, get their money out of it (and I am a stockholder, so buy Ford to help me retire earlier). But that doesn't mean Ford has pivoted back to the V8. Take a look at where there R&D money is being spent. Hint: It's not in V8 development.

Yes, on the face it "appears" there is zero benefit to mds in activation, and to be worse it can create wear by changing cylinders normal function. I would have like to see them just have a 4 cylinder ram for those who want gas mileage, maybe lighten the body to compensate and call it a commuter truck and don't tow with it.

HP is just part of the equation, I got beat to the punch by a freaking 90's chevy tahoe, something I don't even like talking about how way less HP toasted my ram, I had to lift, he straight beat me. Maybe gears, maybe just those chevy transmissions, but whatever the reason HP isn't everything. I believe the holeshot was a wash, he just had better power at the wheels.

One thing I am dissatisfied with in my 6.4 is in the power category. Ford 7.3 smokes it and just feels more relaxed doing it. Ram is in need of updating their v8s

 

[bcbouy]

I hated it more in my 5.7L- seemed much more intrusive.
I started switching it off every time I put it in drive cause I hated the vibration in the pedals (and sound).
For whatever reason I rarely notice it in my 6.4L...

i wonder if it's the 5.7 light duty trucks that feel the mds more than the 6.4 heavy duties? i don't notice it in my p/w unless i actually look at the gauge and see the little green mds lighted up.

I never feel it and I have the 5.7 in a 2012. Maybe the 6 speed vs 8 speed? Maybe different programming? I dunno, like I said it's invisible to me.

 

[Hemi395]

If you have any type of aftermarket exhaust there's no way you won't notice mds lol

Probably sucking the bottle!

I agree when it comes to the F150, it's definitely turbo/electric. But they're still heavily investing in the v8, this latest update cost them a lot of money and so did the 7.3 in the super duty. It's still very much up front on their radar.

I actually did a 200 mile round trip.100 miles without mds and 100 with it Best I could figure about 1/2 mpg better with mds.
You're welcome...I saved the planet! Lol

 

[tones2SS]

So,.........it's safe to say, the MDS SUCKS!!!!
lol

If we wanted a 4 cylinder or V6, we would have bought a smaller truck or smaller engine engine truck. GIVE ME BACK MY FULL TIME V8!!!!!!!

Big a*** DITTO THERE !!!!!

 

[2012RAM1500RT]

As it stands right now if you take the percent of the ones that don't prefer MDS and the ones that hate it with a passion and give them half of the ones that has no opinion either way, then take the percent of the ones that like it and give them the other half of the ones that have no opinion either way it looks like 70% don't like it and 30% does like it! So to me salesman was wrong!

 

[ramffml]

Fun with stats! We can make them look like anything. Did you know that on average, every human has 1 test!cle??

In my opinion though, it's worse than what @2012RAM1500RT said; only 25% actually want it, the ones who don't care are excluded from the weighting because they're not going to buy or not buy a hemi if it has MDS. So if this was back in 2006 at the weekly hemi staff meeting and some guys says "hey lets make it work with 4 cylinders" and they wanted to know if it was a good idea; there is only 25% of ramforum members who value the feature, therefore from a risk/cost analysis perspective, it's kind of a fail.

Of course we have the benefit of 20/20 vision, I doubt Ram knew it would work so poorly in real life before committing to the idea.
