P3Gauges ESVA Ethanol Sensor Voltage Adapter/Adaptor - 0-5V Converter for Ethanol Content & Fuel Temp - Works with Continental/GM Flex Fuel Sensors - For 0-5V Gauges or ECU - E85 Compatible - P3ESVA

P3Gauges ESVA Fuel Composition Interface 0 to 5 Volt Output

Get live fuel composition and fuel temperature into your gauge or ECU with the P3Gauges ESVA. This compact signal conditioner sits between a GM or Continental flex sensor and any device that accepts a 0 to 5 volt analogue input, translating the sensor’s frequency signal into two clean, stable voltage channels for precise monitoring and tuning. Perfect for E85 builds, flex-fuel mapping and data logging where accurate fuel blend information matters.

We run ESVA modules on our own projects and our customers love how consistent and easy to integrate they are. Clear readings, tidy wiring and rock solid stability make it a go-to choice for performance cars running ethanol mixes.

What it delivers

• Channel 1 - linear 0 to 5 volt output representing fuel ethanol percentage for gauge or ECU analogue input
• Channel 2 - linear 0 to 5 volt output representing fuel temperature for display or logging

The ESVA converts the pulse frequency from a GM or Continental flex fuel sensor into reliable voltage signals your instrumentation understands, giving you real-time blend percentage and temperature without guesswork.

Why enthusiasts choose ESVA

• Know your blend - verify E85, E50 or any mix for safer calibration and power consistency
• Protect your engine - temperature insight helps with cold starts, hot fuel and heat-soak awareness
• Seamless integration - straightforward wiring to signal, ignition power and ground
• Trusted performance - proven stability on road, track and dyno

Key highlights

• Works with GM and Continental fuel composition sensors
• Two independent analogue outputs - ethanol percentage and fuel temperature
• Designed for any 0 to 5 V linear input gauge, logger or ECU analogue channel
• Compact module for a tidy, discreet installation
• Made by P3Gauges for accuracy and reliability
• Sensor not included

Compatibility

• Ideal with P3 V3 OBD2 Gauge for on-dash display of blend and temperature
• Suitable for most aftermarket ECUs and data loggers that accept 0 to 5 V inputs
• Supports GM and Continental style flex-fuel sensors commonly used in E85 conversions

Who is it for

• Ethanol conversion builds in need of a fuel blend reader
• Flex-fuel setups requiring an analogue interface to gauges or ECUs
• Turbo and supercharged cars chasing consistent power on varying pump mixes
• Tuners and enthusiasts wanting dependable, loggable fuel composition data
