I'm told its the same box as the euro4 but different internals, but the euro4 is more than capable of running the lotus and it has very similar specs..
The usa efi uses similar hardware (same processor) but different design and software.
The FIA GT Lambo uses an earlier euro unit , more like the 05, i'd posted a list of cars a while ago that used EFI tech, i probably just didn't make it clear it was the italian company.
