Does my 2010 RAM 1500 4.7L V8 have MDS??? No one answered this when I asked before... I have an "eco" light on mine and it turns on and off according to how much gas I'm giving it...
Only the 5.7L HEMI has MDS. The ECO light isn't directly related to MDS, though when you are driving 'eco friendly' and you have a HEMI that is a good time for MDS to kick in. On the 4.7 the ECO light just indicates when you are driving efficiently.
