Description

The Spool Performance BMW Gen 1 B58 Wireless Ethanol Analyzer Kit is a cost-effective solution for monitoring ethanol content and fuel temperature. It provides real-time tracking of ethanol concentration and fuel temperature directly to your smartphone via Bluetooth 4.0. The kit includes a GM ethanol sensor and is designed for easy installation, making it ideal for those running E85 or higher ethanol blends.

The analyzer is crucial because ethanol blends can fluctuate in actual ethanol content (e.g., E85 can range from 51% to 85%). Running a lower ethanol content than your vehicle's tune is calibrated for can potentially lead to engine damage. This analyzer ensures you know the precise ethanol content, allowing for correct fuel mixture adjustments and preventing potential harm to your engine.
