Rolls-Royce models can be programmed on the Bench (Phantom and Drophead with 2 ECUs), or with ETG’s piggyback Performance Module (Ghost and Wraith). To Bench Flash, the ECUs have to be shipped to us Overnight, or we can come to you, remove the ECUs, flash, and reinstall. The Performance Module is essentially a secondary ECU that will serve up the modified engine maps and parameters.
