Fabspeed XperTune Performance Software for F90 BMW M5
Engineered for maximum power gains and drivability without compromising reliability, this solution uses Fabspeed Motorsport’s alternative tuning method for ECUs that once required bench flashing. Instead of removing and mailing the ECU, the included handheld programmer connects to the vehicle’s OBD-II port and a computer to complete the process, allowing the BMW M5 to be flashed with a Fabspeed ECU tune at home. The performance software recalibrates sensor strategies, air/fuel ratios, and boost targets to increase horsepower, torque, and overall driving refinement.
