The latest Magic Motorsport Flex V8.26.0.0 software update adds Korhex support for Bosch MD1CS069 and MD1CS089 engine control units used in commercial and industrial vehicles. Both ECU families are based on the TriCore TC299 processor.
The main change is the addition of a Boot Glitch connection method that does not require direct work on the ECU’s printed circuit board. For technicians working with compatible units, this can simplify the setup process and reduce the time needed to establish a connection.
Boot Glitch or Bench: Two Available Workflows
The new protocol uses a glitch point identified through the relevant mask in the technical manual. Technicians can use this information to position Korhex tool and establish the connection.
After the connection is complete, there are two possible workflows. Users can continue operating in Boot Glitch mode or unlock the ECU and move to Bench mode.
The protocol requires an FLS0.20 Boot Glitch license or a Flex Full FLS0.5M configuration/FLS0.5S configuration.
What Can Be Read or Written?
For supported Bosch MD1CS069 and MD1CS089 ECUs with TC299 processors, the listed memory functions include:
- Reading and writing internal Flash
- Internal Flash checksum operations
- Reading and writing EEPROM
- Full backup
The reported operation times are approximately 30 seconds for connection and glitch, 2 minutes 30 seconds for reading, and 2 minutes for writing.
Actual times may depend on the specific setup and working conditions.
Vehicles Included in the Compatibility List
Examples of supported vehicle applications include:
- FIAT Ducato (V), 2021 model year, with a 2.2L MultiJet III 16v engine rated at 138 HP
- Dr Motor PK8 (I), 2023 model year, with a 2.0L Turbo 16v engine rated at 134 HP
- John Deere 5G Series (5115G), 2022 model year, with a 3.6L 16v engine rated at 114 HP
- Massey Ferguson MF 3xx (I), 2023 model year, with a 3.6L 16v engine rated at 104 HP
- New Holland T5 Series II, 2021 model year, with a 3.6L L4 engine rated at 99 HP
These examples identify vehicle applications associated with the new protocol. Compatibility should still be checked against the exact ECU model and configuration.
What Changed in Flex 8.26.0.0?
The update notes report improved reliability of the Boot Glitch connection.
Combined with the new Korhex Boot Glitch tool support for Bosch MD1CS069 and MD1CS089 TC299 ECUs, this gives technicians another supported workflow for compatible commercial and industrial vehicle applications.
