Audi E85 Conversion — ECU: 8V0906259J / SW: SC800S5000000 — A dedicated E85 fuel conversion file to unlock the maximum performance potential of your S3.
This is a specialized E85 conversion file for the Audi S3 (8V), equipped with the 2.0 TFSI engine and a Siemens/Continental Simos 18.1 ECU. This is not a typical petrol tune; it is a full calibration designed to allow your vehicle to run safely and optimally on E85 ethanol fuel, unlocking significant performance gains beyond what is possible with regular gasoline.
This remap requires an upgraded high-pressure fuel pump (HPFP) to meet the higher fuel demands of E85. The software completely re-calibrates the fuel system, injection timing, and ignition maps to harness the high-octane, cooling properties of ethanol, resulting in a massive increase in horsepower and torque. This is the ultimate fuel solution for the serious enthusiast seeking the highest level of performance.
