What does this mean in the workshop?
EEPROM stores controller data and settings. Reading creates a copy; writing changes the stored content. Check the chip identifier and keep a readable original backup before writing, rather than relying on a file from another controller.
Application scope
- Work on memory data for the specified EEPROM or CPU versions.

Before ordering
This is an ACDP expansion, not the base programmer. Operation requires a compatible host, the appropriate interface and an activated licence for the selected function. We check your existing equipment and the additions required before ordering.
Compatibility review
Send the vehicle model and year, ECU, TCU or IMMO identifier, required function and the serial number of your existing ACDP unit. Support depends on the specific controller, hardware and activated authorisations; the vehicle brand alone does not establish compatibility.
