What settings did you have to change to accommodate the AGM battery, please?
At first I didn't make any changes, but then realized I should edit the battery CCA/Capacity that the car is set to using Forscan to be closer to what the new battery is. Forscan didn't have an exact match (800 and 80 in this case) so I just went for whatever was closest, I think it's currently at 700/80 or 800/70 or something...I would have to check.
It literally just worked once I physically made the change, the settings I changed would be more for proper charging during use/driving.
EDIT: Oh and did a BMS reset which you can easily do without the need for any tools/software.
EDIT #2: Added a picture showing the remaining gap between the leading edge of the battery to the airbox, plenty of room left!
