Overview

The ScienceofSpeed E85 FlexFuel System is a computer and module designed for the Honda S2000. This system adds a composition sensor that communicates the percentage of ethanol in the fuel to your engine management system. The ECU can then automatically adjust fuel, ignition, and boost levels.
Show original supplier description
The ScienceofSpeed E85 FlexFuel System offers a plug-and-play solution for the Honda S2000 (2006-09 models) that enables the use of E85 fuel. E85 is favored by performance enthusiasts for its potential to generate significantly more power from supercharged and turbocharged engines at a lower cost than race fuel. As E85 fuel content can vary seasonally, this system's composition sensor relays the ethanol percentage to the ECU. The ECU then automatically and seamlessly adjusts fuel delivery, ignition timing, and boost levels to safely and effectively utilize the fuel, regardless of its exact ethanol concentration. The system integrates directly into the factory fuel system. It includes a stainless steel bracket for mounting the sensor in a factory-compatible location, requiring no drilling or modifications to the vehicle. All necessary AN and conversion fittings, E85-compliant hose, clamps, electrical connectors, wiring, and terminals are provided. A "return fuel system" conversion is required for 2006-09 S2000 models. **Required:** A FlexFuel-compatible ECU, such as the AEM Series 2 EMS or AEM Infinity, is necessary for operation. This specific SKU (ENPP-2675) is a kit that includes all components except the fuel composition sensor itself.
