Hi
I had the problem of my TCU needed to be reset about once a month. I did the upgrade and replaced my battery. I had to pull F34 fuse to reset Everytime the App stopped working. I even put battery charger in default mode but still had problem. I ended up installing a 12 bolt to 13.8 volt 5 amp DC to DC converter. I installed it right on the TCU. I have pics and notes of current and voltage reading s but can figure out how to insert pics in post.
