Emtron Flex Fuel / Ethanol Content Sensor

The Emtron Flex Fuel Sensor (Fuel Composition Sensor) measures ethanol content in your fuel, allowing the Emtron ECU to automatically adjust fuel, ignition, and boost maps based on the ethanol percentage detected. This enables seamless operation on any ethanol blend from E0 to E100.

• Measures ethanol content 0–100% (E0 to E100)
• Frequency-based output compatible with Emtron ECU digital inputs
• Pre-defined calibration available in Emtune software
• Enables automatic fuel and ignition compensation
• Supports flex fuel operation — pump gas to E85 and beyond
