Spool Wireless Ethanol Analyzer Kit (N55 FXX 2/3/4 series & s55 F8x M3/M4

This ethanol analyzer is for a N55 F3x or can be used on a S55 F8x

The Spool wireless Ethanol Analyzer kit is a very cost-effective and robust ethanol content and fuel temperature monitoring solution. With the included smartphone app, the analyzer paired with a GM ethanol sensor can display the in-tank fuel's ethanol concentration percentage and fuel temperatures in Fahrenheit. The Analyzer module incorporates the latest Bluetooth 4.0 low energy protocol which means very little battery usage on your smartphone and also leaves regular Bluetooth functions and connectivity on your smartphone untouched. 

Ethanol Sensor App

Unlike competitors, our Ethanol Analyzer Apps are truly free of cost and features an Ethanol Mix calculator to make sure you get the perfect blend every time. With an ethanol analyzer kit, the App can automatically populate the in-tank fuel's E-content required for the calculations. The app can be downloaded and used even if you do not have our Analyzer kit and will let you estimate your mixes.
