Yes, happy to share, so I brewed up the perfect situation to have MDS destroy my Hemi. First and foremost, the MDS worked OK, noticed it working on light load conditions, it would make the light sputter sound and maybe it would save a bit of fuel, not sure, I never measured. MDS did not bother me much really. So, the day of failure, early April 2021, afternoon after great fishing at Fish Lake Wa, was hauling my trailer with boat and gear, I had been drinking, so I asked my sober friend to drive the Commander towards the hills to check on the trails we ride dirtbikes on soon.... We ran onto a small field of ice, snow, where we usually park, I said, go for it, with trailer and all, trailer made us stuck... So unhooked the trailer, Jeep was buried too and he tried to drive it out for several minutes, I did not think to ask him as he was stuck to try 4Low, which turns off MDS, so it was MDS on, 100% sure of that, so the motor was not overheating but hot, stopped Jeep to rethink, by now, there was 4 hot and 4 not as hot cylinders. Got the shovel out, cleared a small path, restarted engine, complete engine fail due to all seats on MDS cylinders dropping. Could I have prevented this? yes... I can be an idiot. Was it MDS, no.. Had it had MDS off, it would NOT have happened,all cylinders, valve seats, have equal heat, stay in head! I do not have MDS today, don't miss the fluttering, and I don't have to worry about this ever. I love my Commander! Hope this helps, not biased. Chris.
