BMW N63 W.2 ECU Tune

The Weistec BMW N63 W.2 ECU Tune is a performance flash software engineered to unlock greater potential from your vehicle's N63 engine. Through extensive street and dyno testing, this upgrade reliably extracts substantial power increases, particularly in the mid-range and top end of the powerband, providing a more engaging driving experience. Key features include the elimination of the factory top speed limiter, a noticeable improvement in throttle response, and optimized fuel, spark, and boost parameters. To ensure proper operation and longevity, the installation of upgraded spark plugs is required. It is important to note that actual power gains can fluctuate depending on the specific vehicle model, any existing modifications, the type of fuel used, and current running conditions. This product is not for sale or use in the state of California on any pollution-controlled vehicle, as per the California Air Resources Board regulations. Additionally, all 2020 models require bench flashing. Customers are advised to call to verify compatibility with the Cypher Hand Held Tuner.
