IMMO OFF, Flash and EEPROM, automatic
MasterX recognizes the antistart structure automatically and applies the matching solution on Flash and EEPROM ECUs, file ready to write in seconds.
Flash and EEPROM, recognized automatically
No need to know in advance whether your antistart structure lives in Flash or EEPROM. MasterX identifies it from the binary and applies the correct treatment.
Structure recognition
MasterX reads the file and identifies the immobiliser structure automatically, no manual lookup needed.
Flash & EEPROM
Both storage types are covered on supported ECUs, with the matching solution applied for each.
Ready in seconds
Once your ECU shows as supported, the file is generated automatically, immediately ready to write.
Original backed up
The original file is automatically saved locally and in your cloud space before any change.
Clear compatibility, no guesswork. A solution is marked as supported the moment MasterX officially recognizes it for the exact ECU and software version you loaded. From there, its processing is fully automated under the MasterX strategy for that file.
Check your ECU before you buy
Search the free, public database, brand, ECU family and IMMO OFF availability, before spending a cent.
