ECU Tune for 1997-1998, 1999-2000 BMW 5 Series E39 528

Through custom ECU tuning we are able to provide more usable horsepower and torque outputs by modifying BMW’s cam timing (VANOS) and fuel and ignition maps. Better part-throttle drivability is also obtained. The engine rev limiter is raised to 7000 RPM’s and the vehicle’s top speed governor is removed.  Custom software modifications for larger cam shafts or other modifications are also available. Rear O2 sensor and other emissions monitoring can be disabled upon request for race cars and/or off-road use only vehicles.

You may either mail your ECU to us for programming or upload your tune with the optional ECI cable. Other options include: disable rear O2 sensor monitoring, remove air pump, disable emissions faults, delete EWS (M52 only).
