MDS at idle?
 
Is there a way to switch or activate MDS when you're parked or at idle? just out of sheer curiousity. just seems like it'd help economy if you're idling or parked and only using 4 cylinders

99% sure no.

wouldn't be a terrible idea, idling does hurt MPG.

However, guys with aftermarket exhaust would HATE it. haha

The MDS Kit I picked up for my 4.7 (does not come with one) does this, when in traffic or at a light, basically any time you put your foot on the break it will engage and only run the engine on 4 cyl. and you don't even notice it.

Great idea that would be very smart to implement economy wise.

I usually shut it down if ever I'm stranded in gridlock for any length of time. Remember, sitting with the truck idling gets you 0MPG.

damn, well someone needs to get on that. maybe the folks with DS can make something happen with their tuners

i'd love to have MDS at idle as well, never thought about if it was doing it or not before this thread though. I often leave my truck idling for up to an hour due to needing the inverter running for work.

do they have the kit that Asur got for his 4.7 for the 5.7??

he said that thing works surprisingly well

Well i believe people would be complaining about a odd vibration when only runing on 4 cycl. I think it would throw the balance off and give you a shake u wouldn't want unless they put some expensive engine mounts in, kinda like my honda freaking 250 for one from dealer. R u sure u want 4 on idle lol. Good idea though

No vibrations at Idle as it plays with all cylinders when active, but I don't think they have a kit for the 5.7 that has MDS, that would be like having 2 units fighting over who will shut off the engine cylinders when running at speed? the whole engine would shut down lol

So all it shuts off is the spark and fuel?
