The LEO ACTIVE SOUND generator is unique in the world, as data acquisition is carried out wirelessly via the OBD-II interface. The adapter transmits this data to our sound module via Bluetooth. In its latest version, the LEO 6.0 has a complex audio engine that is able to reproduce recorded engine/exhaust sounds. If desired, additional effects such as "Realistic Mode", an accelerator pedal or load-dependent volume as well as simulated "misfires" can be activated.
