The Spool performance Wireless Ethanol Analyser Kit allows you to monitor the ethanol percentage and fuel temperature of your fuel in real time via a smartphone app. This is an essential upgrade for vehicles running on E85 or ethanol blends, as the actual ethanol percentage at the pump can vary significantly.
Using a GM ethanol sensor and the included Bluetooth module, you can easily check whether the fuel is suitable for your engine tune. This helps prevent engine damage caused by an ethanol percentage that is too low, and ensures you always know exactly what fuel blend is in your tank.
