FERRARI GTC4 LUSSO T 3.9 V8 F151M Engine Control Unit+Key

In 2026, the Engine Control Unit (ECU) and Key Set for the Ferrari GTC4Lusso T (F151M) is a highly sensitive “Security Set” that must be handled as a matched pair. Because of Ferrari’s anti-theft protocols, the ECUs (there are two for the V8 Turbo) are electronically “married” to the vehicle’s keys and the BCM (Body Control Module).

1. Technical Identification & Components

A full replacement set for a “lost key” or “fried ECU” scenario typically includes:

• Primary ECUs (Pair): Two Bosch units (typically part numbers in the 327042, 348122, or 334907 series).

• Key Fobs: Two Ferrari-branded smart keys (typically the square-style fobs introduced in the 488/GTC4 era).

• BCM (Body Control Module): Sometimes required if the security handshakes cannot be reset.

• Lock Cylinders: The physical emergency key cylinder for the driver’s door and glovebox.

2. 2026 Market Pricing (Estimated USD)

Purchasing these brand new from Ferrari is the only way to ensure they can be programmed to the car. “Used” ECUs from cannot be “un-married” from their donor VIN without specialized (and often unauthorized) software.

3. Installation & “VIN-Coding”

• Ferrari DEIS Programming: In 2026, installing these parts requires an active connection to the Ferrari factory servers in Maranello via the DEIS diagnostic system. The technician must perform a “Proxy Alignment” to sync the new ECUs with the car’s existing dashboard and gearbox.

• Key Learning: The keys must be introduced to the car’s immobilizer system. This usually requires a security code card that was delivered with the car when new. If you don’t have this card, the dealer must request the code from Italy (approx. $500 fee).

4. 2026 ECU “Cloning” Strategy

If your GTC4Lusso T has a physically damaged ECU (e.g., water damage) but you still have your original keys, many specialists in 2026 offer an ECU Cloning service.
