ECU Tune for 2003-2005 BMW Z Series E85 Z4
E85Z4
Through custom ECU tuning we are able to provide more usable horsepower and torque outputs by modifying BMW’s dual variable cam timing (VANOS), DISA, 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 headers or other modifications are available.
