Immo & Key Programming
Xhorse Multi Prog is a bench programmer for reading and writing ECU, EEPROM and MCU memory across a broad range of automotive control units. It supports engine ECUs, immobilizer components, dashboards and microcontrollers through adapters and in-circuit/ISP connections, and is designed to speed up bench work with pre-defined menus for many modules. Specialists use it to read original ECU data for cloning or immo adaptation, extract EEPROM dumps and program replacement units. It integrates with the wider Xhorse ecosystem and receives ongoing software updates adding module coverage. Multi Prog requires its dedicated device and Windows software. Its focus is chip/ECU-level reading and writing on the bench rather than in-vehicle diagnostics or calibration editing.
Multi Prog reads ECU/EEPROM/MCU memory on the bench; Softechpro then works on that engine-ECU firmware image to auto-apply DPF/EGR/AdBlue/DTC-off modules and correct checksums for supported files. Softechpro edits the file rather than reading the chip.
