I am considering one of these and having a bit of experience with other diagnostic scan tools, I have learned that what is advertized isn't always what the tool can do. So I contacted the manufacturer of the tool. They tell me one thing, yet other sites tell me otherwise - "Battery registration (for the same battery type and capacity with the original)". That tells me as long as I replace the old battery with the same. And what if I want to install a higher capacity battery? The 991 can take three battery sizes and therefore capacities.
Foxwell put me onto this YouTube site from Pelican Parts. Unfortunately, the video does not show use of the diagnostic tool, so it does not tell me anything.

Foxwell also included this screenshot in the email. Now I may be wrong, but that screen looks a lot bigger than the screen of a NT510 Elite. And as it should, it lists 4 windows to enter battery data in: Capacity - Type - Serial Number - Part Number.
Has anyone used one of these on a 991 and if so have they done a BMS Battery Registration and an ABS Brake Bleed?
