BMW N55 F22 235i, F30 335i & F32 435i Spool Wireless Ethanol Analyzer Kit

The Spool wireless ethanol analyzer kit for N55-powered BMW 2, 3 and 4 Series models 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.

Fits

• BMW F22 M235i (N55)
• BMW F30 335i (N55)
• BMW F32 435i (N55)

What's included

• Spool wireless ethanol analyzer module (Bluetooth 4.0 low energy)

Good to know

The lines fit the OEM high pressure pump or Spool FX-150 and FX-180 pumps and are fully ethanol compatible. 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.
