Can I use my Bluefin on more than one vehicle at a time?
The Bluefin is designed to become tied to one vehicle and, therefore, cannot be used on two vehicles at the same time. It is, however, possible to use the Bluefin to program one vehicle with the Superchip modification, then pay for the unit to be reset, at a reduced price from the RRP of a new unit, for use on a subsequent vehicle. This would, of course, mean that it could not be used again on the original vehicle as it will be tied to the current vehicle.
