Except for ECU/ TCU cloning, VVDI Multi Prog could write modified files to certain ECUs.
All ECU options marked by “C” support checksum.
Here comes a review of IMMO OFF using Multi Prog:
Success in reading and writing immo off for med9.1 vw Passat
Search for BOSCH number and confirm ECU type.
Connect ECU to device by diagrams.
Read original data.
Write modified data file into module and checksum okay.
Done! Simple and nice!
