Monitor your ethanol content and fuel temperature with precision and confidence using the Spool Performance BMW Gen 2 B58 Wireless Ethanol Analyzer Kit—an essential tool for any enthusiast running ethanol-blended fuels. Designed specifically for Gen 2 B58 engines, this analyzer kit provides real-time ethanol percentage and fuel temperature data directly to your smartphone using a high-accuracy GM ethanol sensor and a Bluetooth 4.0 LE-enabled analyzer module.

Whether you're dialing in a custom tune or verifying the ethanol content of your fuel, this compact and powerful kit eliminates the guesswork. The wireless Bluetooth module transmits fuel data to the Spool Ethanol Analyzer App, which includes an E85 mix calculator to help you blend fuel accurately and avoid the risk of running too lean or rich. With ethanol pump blends ranging anywhere from E51 to E85, this tool is a must-have to ensure your vehicle is running safely and efficiently.

The analyzer is fully E85 compatible, features a plug-and-play installation, and consumes minimal power thanks to Bluetooth 4.0 low-energy technology, allowing full compatibility with all existing smartphone Bluetooth functions. The app is completely free of charge and does not require subscriptions or in-app purchases, offering unmatched functionality right out of the box.

As part of the kit, you can optionally include the Spool Performance 10-Micron High-Flow Fuel Filter, constructed from high-quality aluminum and stainless steel. Designed for durability and long service life, this filter is washable, 100% E85 safe, and rated to flow over 6 GPM, far exceeding the fuel demands of even the most aggressively modified B58 platforms.

Why Use an Ethanol Analyzer? Ethanol fuel variability is a major concern for performance builds. Pump E85 can range from 51% to 85% ethanol content depending on region and season. Without knowing the actual ethanol percentage in your tank, you run the risk of misfueling a car tuned for higher ethanol content—potentially resulting in serious engine damage. This analyzer gives you real-time visibility and control over your fuel system.
