Overview

The Gen 3 Continental GT V8 shares the modern EA825 twin turbo V8 architecture used across high performance VW Group platforms, but Bentley calibrates it for smoothness and luxury first. That leaves very useful ECU tuning headroom, especially in the midrange and upper rpm range. Because the car is lighter over the nose than the W12, gains feel especially immediate and responsive. Stage 2 suits this platform well with downpipes and intercooling support.

Key Features

  • quick turbo response
  • strong power to weight feel
  • modern EA825 tuning headroom
  • improved part throttle urgency
  • excellent Stage 2 potential

Programming Instructions

The Bosch MG1CS008 ECU requires bench flashing — direct connection to the ECU outside the vehicle. The ECU must be removed and shipped to AMT Tuning for programming.

  1. Remove the ECU from your vehicle (refer to your workshop manual for location and procedure)
  2. Package securely and ship to AMT Tuning at the address below
  3. AMT will read your stock file and flash your custom tune directly on the bench
  4. Turnaround is typically 3–5 business days from receipt
  5. Reinstall the returned ECU — the tune is active immediately on start-up
