The Spool Performance Wireless Ethanol Analyzer 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.
With the help of a GM ethanol sensor and the included Bluetooth module, you can easily check whether the fuel is suitable for your tune. This prevents engine damage caused by a low ethanol percentage and ensures you always know exactly which fuel mix is in the tank.
