Show original supplier description

The Weistec M278 ECU Tune is a reflash of your original ECU, engineered to significantly enhance the performance of the M278 engine. This performance upgrade delivers a substantial increase in power, reaching up to 540 horsepower and 715 ft-lbs of torque on California's 91 octane pump fuel, all while remaining street legal. The tune meticulously optimizes boost, fuel delivery, and spark timing, leading to increased throttle response and the elimination of the factory top speed limiter. Developed in-house after extensive dyno and road tuning, this ECU tune represents the most powerful upgrade available for the M278 engine. It is CARB Exempt with EO# D-691-1, ensuring compliance. The process involves reflashing your original ECU. Optional recommended products for further enhancement include the Cypher Handheld Programmer, High Flow Air Filters, and one-step colder spark plugs. Compatibility is key; this ECU tune is specifically designed for the Mercedes-Benz M278 engine family. Vehicle applications include the 2015-2019 Mercedes-Benz SL500 Roadster (R231) with the Twin Turbo 4.7L V8 (M278) engine. Please note that the Cypher Handheld Programmer, an optional accessory, is not compatible with 2020 and newer models.
