Fabspeed XperTune ECU Software for BMW M5 (F90, 2017–2020)

XperTune recalibrates the F90 M5 engine management for the car’s fuel and hardware. This listing uses a handheld OBD interface, with a production-date cutoff that must be checked before ordering. Based in Fort Washington, Pennsylvania, Fabspeed Motorsport designs exhaust, intake and ECU-tuning products for Porsche and other sports cars. Development includes evaluation on a dynamometer, on the road and at the racetrack.
