This not right unless Ben made it that way on new boxes. Once you go into auto mode weather you let off the throttle or tap the brake it should always revert back to auto mode with blue light. At least that's how mine is. So it looks like all your functions are right except auto mode not staying on when you tap the brake.
I wonder if its the wore going to the brake did you triple check that.
Mine does the same thing as his, but my box doesn't look like his. Granted mines an lbz. I bought mine like a month ago from Dustin at diesel addiction. So I'm thinking might be an older unit?
