Flex version 8.31.0.0 introduces Korhex unlock support for Bosch MD1CP007, MD1CP017, and MG1CS028 ECUs used in Jaguar and Land Rover vehicles.
With the UOBDII Black Friday promotion also underway, workshops can explore the new capabilities while saving on selected FLEX software, hardware, and Korhex packages.
Unlock JLR ECUs Without PCB Modifications
Previously supported through Voltage Fault Injection (VFI) technology, these ECUs can now also be unlocked using Korhex without modifying the PCB, reducing operation time and simplifying the procedure.
Once unlocking is complete, you can continue directly in Bench mode for reading and programming operations.
