RACING ECU TUONO RR/FACTORY MY -CM281708

Dedicated engine control unit for track use, pre-programmed with racing ECU mappings. For use on bikes fitted with aftermarket exhaust systems (complete systems or slip-on muffler) NOT supplied by Aprilia. Recommended for use in combination with exhausts with no catalytic converter, with or without Db-killer. Dedicated ECU mapping (with three R/S/T settings) to exploit the full potential of the exhaust. Unlike the standard ECU mapping, all three R, S and T maps deliver unlimited power - the S ECU mapping offers smoother response, whereas the R ECU mapping limits torque in the first three gears. After installation of ECU by an authorised Aprilia service centre, later updates may be downloaded and installed. For track use only.
