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.
You may either ship your ECU for programming or upload your tune with the optional ECI cable. The ECI cable requires a separate "OBD to 9-Pin" adapter available from many online retailers (not from BimmerWorld). This will allow communication through the round diagnostic port in the engine bay.
