Fabspeed XperTune Performance Software For E9X BMW M3

Achieve maximum power from the BMW M3 V8 engine without sacrificing drivability or reliability by optimizing the engine's performance. Fabspeed Motorsport offers an alternative tuning method for vehicles equipped with ECU's that traditionally required bench flashing. No longer do you need to remove your ECU and mail it in for a tune. The Handheld device interfaces with the OBD-II port on your vehicle and your computer to complete the tuning process. Simply flash your M3 with a Fabspeed ECU Tune utilizing the included handheld tuner. Performance ECU software upgrade improves horsepower, torque, and driving characteristics by reprogramming various sensor inputs, air/fuel ratios, and boost pressure (if applicable).
