With the latest FLEX update, version 8.17.0.0, Mercedes Bosch ECUs equipped with SPC5777 processors are now supported via Korhex and the EMFI — Electromagnetic Fault Injection technology.

This procedure simplifies access to the unit: no need solder the PCB nor to remove components.

Less steps, more autonomy in your workshop.

Place Korhex, follow the Flex-guided procedure and access the SPC5777 microprocessor.

To perform these operations, you need the FLS0.20 license or the Flex Full FLS0.5 configuration.
