Do you have the right license? I was going through the menu items on my BUDs, but unless you have the Mechatronics Expert license, I don't think you can't mess with DESS or SPARK settings.
i have the Mechatronics Expert licence so should be able to boost from 60 to 90hp but i can only find the info for using BUDS on older sparks(pre 2017) and not BUDS2. the spark i want to re power is a 2020 model.
