Great news for shops working on commercial and industrial vehicles: Magic Motorsport has released Flex version 8.26.0.0, and it brings KORHEX support to Bosch MD1CS069 and MD1CS089 ECUs running the Infineon TriCore TC299 processor.
Boot Glitch Without Touching the PCB
With this update, technicians can run the Boot Glitch procedure without working on the ECU's circuit board. That makes connection simpler and cuts down on working time.
Just use the mask shown in the manual to find the right glitch point, then place the KORHEX quickly and accurately. Once you're connected, you can choose to keep working in Boot Glitch or unlock the module and carry on in Bench mode.
