Bench / BSL / Boot Tool
BSL100 denotes a bootstrap-loader (BSL) bench tool used to access Tricore and similar microcontroller-based ECUs through their BSL/boot pins, the successor access method to the older BDM approach. In BSL mode the ECU's microcontroller is forced to accept an external loader, letting the tool read and write flash on modern Bosch EDC17/MED17-class and comparable units on the bench. Tuners use it for full firmware access, recovery of locked or bricked ECUs and reading protected areas that OBD cannot reach. It requires opening the ECU and connecting to the correct boot pins, typically via a frame or adapter, and pairs with software that manages the loader and checksum handling. Exact coverage depends on the supported microcontroller list.
A BSL tool provides the low-level read/write on modern ECUs, and Softechpro Solutions does not replace that hardware. Once the firmware is out, Softechpro applies DPF/EGR/AdBlue/DTC-off modules and corrects the Tricore checksum for you.
