I figured that was obvious...I really don't like MDS. I have the same aversion to stop/start but that was a lot easier to permanently disable.Imagine judging every product of industry this way.. or why only MDS specifically and not transmissions, fuel injection, tires, nav (you don't need to figure out how to fold your android auto maps like a 1981 map...) ..
Just specifically MDS. For some reason.
My 17 Ram 5.7 has the eco mode and its so smooth you can only tell by the green light. I have 141,800 miles and had no problems. Oil changes every 6,000 miles, and high idle hours.Don't get me wrong. I love my new Ram. It's just that crawling around town in ECO mode I can both feel and hear it lugging along on 4 cyls. I just can't get it out of my mind that in the long run it just won't be good for it. I'm pretty old school and that always meant don't lug your engine. So I am sort of making it a point now of taking it out of ECO mode, at least for around town. Besides, trading in the old Tundra has improved the gas mileage no matter how you look at it.
I had my Hemi for 7 years with MDS I can honestly say I never even noticed it. I think it's not flat enough in MA for it to ever kick in but that was a 2012 with 6sp auto??Don't get me wrong.

You just may be correct.Nobody who understands the phrase dynamic compression ratio is in a hurry to delete MDS.
Nope. Not on mine. Only manual shift mode works.Put it in Tow/Haul. I do it all the time.
That is true, I did not think of that. Guess will just keep using the button to deactivate it as is about a thousand bucks to have a shop re program the computer.Just disconnecting the MDS solenoids is only part of it. You would still have the fuel and spark for those cyls that the ECU controls, as an issue to still deal with.
Since the Hellcats have oil squirters for the pistons / pins, why couldn't something similar be done for the 5.7 lifters / cam? Perhaps even something aftermarket using the excess supply of oil when the hellcat pump is used.The “modern” Hemi is a design failure! V plan is to flat, you dont get the windage needed to sling oil to the top of the engine is 1 main problem. I have Never seen sooo many Hemi engines with rusted lifters. Plus the camshaft and vvt/msd just contributes to the oiling problem. This engines top end is starving for oil! I dont care how many times you change it with whatever X brand of high dollar oil.
