- Five short guides cover cable setup, backup reads, flashing, DME identification, and recovery after a failed write.
Field notes
The guide list gets into concrete setup details, including cable chip choice, Windows drivers, COM-port configuration, and a 1 ms latency setting. It also treats flashing as the risky step, advises keeping an original file, and includes a recovery guide. The maker describes the software as untested and warns that modifications can affect the engine or gearbox.
