From the developer:
The NIStune hardware and software solution provides a means for the car enthusiast to retune their
vehicle whilst retaining the factory ECU and its default programming.
This solution provides many advantages over aftermarket ECUs in that the factory default tuning is
maintained once the NIStune board is installed. Upon installation of the board the vehicle will be
operational as usual.
