I don't know the answer.

I have an MM3, and I haven't installed it yet.

I was curious, once I flash the new tune to the truck, can I unplug the MM3 and not use it as a monitor?

Will the tune still be installed, and will the truck run fine with the unplugged screen?

I don't want to risk someone stealing the tuner from my truck, so I would rather not have it in the truck at all times.

I only care about monitoring the truck when I'm towing, or does it always have to be plugged in?
