Korhex is a Magicmotorsport accessory for supported direct MCU access and ECU unlocking procedures used with Flex. The manufacturer describes electromagnetic fault injection (EMFI) and Boot Glitch procedures followed by Flex read/write operations.
Requirements
Magicmotorsport lists Flex Full or the separate Flex Boot Glitch licence as eligible configurations. Support depends on the exact ECU, MCU, vehicle and Flex protocol; consult the live Flex vehicle list and instructions. Do not assume a listed processor makes every control unit with that processor compatible.
