The Spool Wireless Ethanol Analyzer Kit offers a cost-effective and reliable way to monitor ethanol content and fuel temperature in your vehicle. Paired with a GM ethanol sensor and our free smartphone app, the analyzer provides real-time data, including ethanol concentration percentage and fuel temperature (in Fahrenheit). Utilizing the latest Bluetooth 4.0 Low Energy (BLE) protocol, the analyzer ensures minimal battery usage while leaving your smartphone's standard Bluetooth functions unaffected.
Why Do You Need an Ethanol Analyzer?
According to the latest ASTM guidelines, ethanol blends labeled E85 can contain anywhere from 51% to 85% ethanol. This variability means the E85 at your pump might actually be E55 (55% ethanol), which can pose serious risks to vehicles running performance E85 tunes.
Using a tune optimized for higher ethanol content with fuel containing less ethanol can lead to engine damage. With the Spool Ethanol Analyzer Kit, you’ll know the exact ethanol content in your tank, ensuring your engine runs safely and efficiently.
Ethanol Sensor App
Our app sets a new standard by being completely free and packed with features, including:
- Ethanol Mix Calculator: Helps you achieve the perfect fuel blend.
- Automatic in-tank ethanol content readings with the analyzer installed.
- Standalone use for estimating ethanol blends without the analyzer.
Upgraded Fuel Lines
The kit includes 6AN PTFE-core fuel lines with black nylon coating and braided stainless steel construction. These lines are designed to handle extreme pressures and are fully ethanol-compatible, providing the durability and reliability required for high-performance applications.
Available fuel line options:
- HPFP to Fuel Tank [Long Line]
- HPFP to OEM Line [Short Line]
All lines come with anodized aluminum PTFE fittings, ensuring a secure and leak-free connection.
Lifetime Warranty
As with all Spool Performance products, the Ethanol Analyzer Kit is covered under our Lifetime Warranty Program, guaranteeing the quality and reliability you expect.
