ECU Tune for 2006-2008 BMW Z Series E85 Z4M

Through custom ECU tuning we are able to provide more usable horsepower and torque outputs by modifying BMW’s dual variable cam timing (VANOS), drive by wire tables, and fuel and ignition maps. Better part-throttle drivability is also obtained. The engine rev limiter is raised to 8200 RPM’s. Rear O2 sensor monitoring can be disabled upon request for race cars and/or off-road use only vehicles.


E85 Z4M

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.
