This work concerns an Audi S3 with a 1.8-litre turbocharged engine and a Bosch ME7.5 control unit. The software service covers engine management calibration and burble/crackle-style sound settings.

These settings alter engine behaviour in certain operating conditions and can make the exhaust more pronounced when the accelerator is released. The specific result depends on the vehicle configuration and selected software.

No before-and-after power measurements are provided for this car, so a numerical power gain cannot be attributed to this calibration.
