MDS cant come on at any speed....maybe you are confusing MDS with the ECO light on the dash?
Anything over 20mph on mine, level road, no load, just cruising, and the MDS does kick in on my '10.................and it's not just the ECO light. I can tell by the exhaust note change. The infamous 4 cylinder sound.MDS cant come on at any speed....maybe you are confusing MDS with the ECO light on the dash?
The eco light just means you are not driving it hard enough, lay into the throttle!
My '10's MDS is so "aggressive", that it'll stay on at 75-80mph on flat Interstate driving too. When I say aggressive, I mean that any chance that it gets to go to the MDS mode, it will.It will not come on less the 20mph or over 70mph per the manual. Mine comes on anytime I let off the throttle (in that range), going down hill, or a flat road. Anytime the computer determines that it only needs the four cylinders, it turns it on. I find myself using autostick,paddle shifting most of the time to keep it off....mostly out of fear of the timing chain issue.
+1. I used to like the idea of having my cake (V8) and eating it (fuel economy), but given the added complexity, annoying characteristics (noise, vibration, lag) and reliability concerns (timing chain) it's become clear to me, once again, that there's never a free lunch. Aftermarket exhausts make the MDS mode and transitions heinous, and yes, this takes place as soon as the load drops, which is quite often in Drive. For a potential 2 mpg extra it's not worth it to me.Some folks use auto stick, and some buy a tuner to turn it off.
I've figured that the MDS get me about 2mpg more than without it. A lot depends on the roads. I've got a lot of hilly areas, and I can get about the same mpg with the MDS active, or using autostick on these, at 65mph. Just too many hills, and it's always kicking in and out.While I may be in the minority on this, I do agree MDS is annoying when it kicks in, but it does a decent job at increasing my mpgs. In the city I was averaging 9mpg with MDS turned off, now that I reactivated it I'm getting 13mpgs. Mds does nothing for me on the highway as I have a lead foot in autostick mode and sports mode engaged, but I still manage a nice 18-20 mpgs on the highway

Right...but he said at every speed, meaning, less than 20 MPH the way I read it.Anything over 20mph on mine, level road, no load, just cruising, and the MDS does kick in on my '10.................and it's not just the ECO light. I can tell by the exhaust note change. The infamous 4 cylinder sound.
Same at any hiway speed with the above same parameters.
Thanks for stating that, Mike. Many believe that the ECO light IS an MDS light and I've argued against this here pretty hard before. A quick online search showed me that people are confused about this on various forums about 50% of the time.You can get the eco light at about 5 MPH and light throttle, so thats why I assumed that was the issue....we have lots of customers who call and say MDS wasn't turned off, since they still see the ECO light, assuming they are tied together.
