A: No. It is primarily for European vehicles, and not every ECU within a brand is supported. Always check the detailed ECU list before purchasing.
If a vehicle's original ECU suffers water damage or hardware failure, buying a brand-new ECU from a dealer can cost thousands. Buying a cheap, identical used ECU from a salvage yard is a great alternative. However, a used ECU will be locked to the donor car's immobiliser code. Alpha immo decoding allows a technician to virginise or "clone" the original data onto the donor ECU so the car will start.
