Ok so the short story is i have a 2013 ram 1500 crew and at 120,000 mile i lost the cam like so many other on here so i picked up an 2018 5.7 with 14,000 miles on it and in one day
a friend and i removed and replaced the old for the newer 5.7 from day one with the newer engine i have been manual shifting up to 6th each time i put it in drive to keep the MDS from working so yesterday i had a shop friend of mine deactivate the MDS with his HPtuner and leaving the shop the ECO light is still coming on. I have stock exhaust so with out diving by a wall or something sending sound back at me i can't tell if the light is coming on and the MDS is working or not working but the light is coming on. Normally going by buildings i can hear it with the window down but i could not last night. Just wondering if the light comes on even after you delete MDS ?

Thanks
Roger

The light lets you know that you're driving economically friendly. You can turn it off under the connect settings.

Eco does not necessarily mean MDS is engaged. You'll tend to see it come on when you let off the gas, driving at slower steady speeds; as bran said, driving economically.
