VKB-SIM

I bought a VKB MCG GF MKIII without Z axis and there is a "black" blackbox.In VKBDevCfg show origin firmware is "Twist".Which firmware I need to update?_BlackBox_MK2_ with TWIST or without TWIST firmware?

If the grip is a MCG Ultimate this is the file you'll have to flash: _BlackBox_MK2_GF_MCG_Ultimate_v2_09_0.vkb.
