Frequently asked questions
Can every control unit be recovered?
No. The outcome depends on the hardware, the type of failure and the available data. You receive an assessment before any work is charged.
Which files help with ECU recovery?
Every file you have read from the unit, including backups saved by the tool before the write, and the log of the failed write.
