You can keep resetting the code until the pack is blackened toast, but you're not going to get good performance out of the pack until you refurb it. The sooner you do so, the easier it will go in terms of how easy the refurb will be and how many cells will be scrap.

And similar to what Bob Wilson said, if you want to bring the Insight over to my (heated) garage for a battery swap or MIMA install day, I'm game.
