It didn’t come with the VESC but it fits perfectly. You can get one on Amazon! I’m not worried about corrosion inside the watercooled alu block. Even if it corroded a bit, so what? Haha but yeah it wouldn’t hurt to run fresh water in it periodically or even some corrosionX. For now, I simply blow out the excess water and it seems to be holding up fine! (I always ride in salt water)

No. When we have new firmware version, I will update.

You could anodize to be more corrosion resistant, it’d look good in blue!

I’m running battery operated 3v submersible pump in a small tank of antifreeze/coolant in constant circulation to the esc. Using the same type of pump for a bilge pump just in case…
5 Pumps for around $8 with shipping from Bangoods…
