ECU Tune for 2000-2004 BMW 5 Series E39 M5

Through custom ECU tuning we are able to provide more usable horsepower and torque outputs by modifying BMW’s dual variable cam timing (VANOS), throttle, and fuel and ignition maps. Better part-throttle drivability is also obtained. The engine rev limiter is raised to 7200 RPM’s and the vehicle’s top speed governor is removed.  Custom software modifications for headers or other modifications are also available. Rear O2 sensor and other emission monitoring can be disabled upon request for race cars and/or off-road use only vehicles.


E39 M5
