Epic Street Software - E36 M3, MZ3 S52

Through custom ECU tuning Epic Motorsports is able to provide more usable horsepower and torque outputs by modifying your 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 and the top speed governor is removed.

Custom software modifications for larger camshafts or other modifications are also available. Rear O2 sensor and other emissions monitoring can be disabled (see related items) for race cars and/or off-road use only vehicles.

Our software is installed via a D-CAN cable (included) and your Windows laptop (compatible with XP, Win7, Win8, and Win10). The D-CAN cable is included at this price. Read and email your stock file and a tuned file will be returned to you. This is better than off-the-shelf tunes that never look at your original software.
