Title: Bosch ME7.3H4 (0 261 208 206) – Immo Off / Clone to Identical ECU
Post by: Ampersent on March 02, 2026, 08:59:34 AM
Hello colleagues,
I need a tested immo off solution for the following ECU:
Bosch ME7.3H4
HW: 0 261 208 206
SW: ME73H4F022
Fiat/Lancia number: 0 055 195 272
The ECU is from a Lancia vehicle.
I am transferring the data to another ECU with identical HW and SW numbers.
Flash was successfully read via KESS.
EEPROM (95040) can be read in boot mode, but writing appears to be protected.
Full backup (flash + EEPROM) is available.
I am looking for a reliable immo off solution (flash or EEPROM based).

Thank you in advance.
