This service provides a complete plug-and-play ECU replacement solution for BMW Motorsport vehicles equipped with the Bosch ME17.2.5 engine control unit. This ECU is used on the high-revving S65 V8 (BMW M3 E90/E92/E93) and S85 V10 (BMW M5/M6 E60/E63/E64), both of which are known for strict immobilizer synchronization requirements and sensitivity to flash corruption.

The ME17.2.5 ECU can suffer from internal hardware faults, corrupted flash data, failed tuning attempts, or no-communication issues. Using professional BDM-style bench tools, all operational data from your original ECU is transferred to your replacement module, including:

• EEPROM data

• Flash memory

• ISN (immobilizer synchronization)

• VIN transfer

• Software configuration and coding

• Adaptation data when supported

Your replacement ME17.2.5 DME will function exactly like your original and install as a true plug-and-play module without dealer programming.
