Bench / BSL / Boot Tool
BitBox is a modular ECU tool combining hardware adapters with software modules, each sold separately for a specific ECU family. It focuses on bench and boot/BSL reading and writing — including BDM, JTAG and boot connections — for Bosch, Continental, Delphi, Marelli and other controllers, with some OBD support. Popular for its per-module pricing and coverage of locked units, it is used by tuners who buy only the modules they need. BitBox handles low-level reading, programming and, in some modules, integrated checksum and decoding helpers; calibration edits are typically done in WinOLS or similar editors. It is favoured for chip-level access to protected ECUs.
Softechpro Solutions edits the images BitBox reads on the bench, auto-applying DPF/EGR/AdBlue/DTC-off and Stage modules with checksum correction across ~1,400 firmwares. It complements BitBox's low-level read/write and does not replace the bench hardware.
