Bosch ME7.7.0 Immobilizer Data Reading & Emulator Setup for Smart 451 ForTwo

Bosch ME7.7.0 ECU Service for Smart 451 ForTwo — Immobilizer Data Reading & Emulator Setup

This service is specifically designed for Bosch ME7.7.0 ECUs used in Smart 451 ForTwo vehicles. It is intended for situations where the original immobilizer system has failed, the ECU has been replaced after damage (overvoltage, short circuit, water damage), or when the vehicle no longer recognises the keys.

By sending us your Bosch ME7.7.0 ECU, we will:

• Read and verify all data from your ECU (95080 EEPROM and ST10F275 internal memory)
• Decode immobilizer synchronisation data unique to your unit
• Configure and adapt our UNICAN 2 immobilizer emulator specifically for your ECU
• Wire and install the emulator on the CAN bus connection of your ECU
• Thoroughly test the complete assembly on the bench to ensure flawless operation
• Return the ECU + emulator ready to install in the vehicle

The service includes the cost of the UNICAN 2 emulator. Once completed, you will receive your Bosch ME7.7.0 ECU with the emulator properly configured and ready to start your Smart 451 ForTwo, assuming all other components (engine, sensors, wiring, immobilizer module, etc.) are in proper working order.

Why an emulator and not IMMO OFF?

• ✅ No internal modifications to the ECU — EEPROM, firmware and calibration data remain 100 % original
• ✅ Fully reversible — remove the emulator and the ECU returns to its original state
• ✅ Emulator programmed using real synchronisation data extracted from your ECU
• ✅ Bench-tested on an actual Smart 451 ME7.7.0 unit before shipping
• ✅ CAN-based solution — works on Smart 451 where K-Line solutions cannot
