BMW F10 M5 & F06, F12, F13 M6 Spool Wireless Ethanol Analyzer Kit

The Spool wireless ethanol analyzer kit for the BMW F10 M5 and F06, F12 and F13 M6 shows your in-tank ethanol percentage and fuel temperature live on your phone.

Why you need it

Under ASTM guidelines, fuel sold as E85 can contain anywhere from 51% to 85% ethanol. Running a lower ethanol blend on a tune built for more can damage your engine. Knowing your exact ethanol content lets you blend and tune with confidence.

Good to know

The lines are fully ethanol compatible and built to fit the OEM high pressure pump setup. The analyzer uses Bluetooth low energy, so it barely touches your phone battery and leaves your other Bluetooth connections alone. Fuel temperature reads in Fahrenheit. The app is free and its mix calculator also works without the kit.
