The 4.2L FSI V8 is one of Audi's most celebrated naturally aspirated engines. Ecotune software for this platform is designed to sharpen the driving experience, providing a more aggressive throttle map and optimizing the fueling and ignition timing for 99 RON fuel. The result is an engine that feels more eager to reach its high-redline limits, with improved torque throughout the rev range.
