AlphaOBD question

[ljinnc]

Can MDS on a 2019 Ram 1500 Hemi 5.7 non e-torque be turned off using Alpha OBD? If so, do you know the steps? Thanks

I don't recall anything like that.

MDS is part of the powertrain control module, and that is generally off limits for changes via obd2 in our trucks. there's a whole PCM unlock requirement for engine performance tuning and thats the area I would expect etorque/MDS functions to fall into.

It's actually easy to do while driving. Just punch the "Gear limit" buttons on the bottom right of the wheel. Keep pushing until you are in "8", but not "D8"
This limits the highest gear you can select. Putting it in "8" leaves all the automatic shifting as normal, but locks out MDS.
