    so yesterday i went to adjust a tune in my truck, but my diablo sport tuner decided not to turn on. i noticed what looked like a power/charging port, but am not sure. it's been in the box for probably a year. Any help is awesome, thanks!

    Did you remember to turn the key on? That is NOT a charging port, its for power when you download tunes threw you home computer.
