Magicmotorsport has added Korhex support for a group of Jaguar and Land Rover Bosch ECUs, listed on its site as the Bosch MD1CP007, MD1CP017 and MG1CS028 with a TC298 processor. Korhex unlocks the ECU and Flex then reads and writes it on the bench. These were previously dealt with using voltage fault injection, so this is a cleaner route. We hold the Korhex hardware and the Flex licence level it needs, so it is a protocol our tools can use. The source does not call it Beta.
Which ECUs
The release comes with Flex software 8.31.0.0. Magicmotorsport says the Korhex unlock needs no modifications to the PCB, and the work is then done in Bench mode. It lists a read, write and checksum of the internal flash, read and write of the internal EEPROM, and a full backup. The quoted times are about 30 seconds to connect, about 2 minutes 30 seconds to read and about 2 minutes to write. The licence needed is FLS0.20 or the Flex Full FLS0.5 configuration. The new protocols are not named in the source, and it gives example model years of 2020 to 2022.
Cars this opens up
Magicmotorsport shows five example vehicles and links to a longer supported list on its own site:
- Jaguar XF (X260), 2020 model year, 2.0 litre D200 mild hybrid
- Land Rover Discovery Sport (L550), 2020 model year, 2.0 litre D200 mild hybrid
- Land Rover Defender (L663), 2021 model year, 3.0 litre P400 mild hybrid
- Land Rover Range Rover (L460), 2021 model year, 3.0 litre D350 mild hybrid
- Land Rover Range Rover Sport (L461), 2022 model year, 3.0 litre P440e plug-in hybrid
These are examples, not the full list, so check the exact vehicle and ECU against the Magicmotorsport release first.
What it means
For owners of these larger Jaguar and Land Rover models, a calibration is usually about stronger, smoother delivery and better pull when the car is loaded or towing. Mild hybrid and plug-in systems add complexity, so a proper read and backup of the original file matters first.
For dealers, bench access without PCB work means a safer job and a quicker turnaround. Owners can look at the tuning builder, dealers can use our file service, and the Magicmotorsport Flex page has the tool detail.
