BMW E9X, E8X & E6X N54 & N55 Spool Wireless Ethanol Analyzer Kit

The Spool wireless ethanol analyzer kit for E-series BMW N54 and N55 cars 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, so knowing the exact content lets you blend and tune with confidence.

Fits

• BMW E90 / E92 / E93 3 Series (N54 / N55)
• BMW E82 / E88 1 Series (N54 / N55)
• BMW E6X models (N54 / N55)

Features

• GM ethanol sensor with Spool Bluetooth 4.0 low energy analyzer
• Ethanol content and fuel temperature (Fahrenheit) readouts
• Free Spool app with ethanol mix calculator
• 6AN PTFE-core fuel lines with braided stainless and black nylon coating
• Anodized aluminum PTFE fittings

Good to know

Pick your chassis (E9X/E8X or E6X) and line version at checkout. The long line runs from the high pressure pump to the tank, for cars with an upgraded fuel line; the short line connects the high pressure pump to the OEM line. The app is free and its mix calculator also works without the kit.
