BMW Gen 2 B58 Spool Wireless Ethanol Analyzer Kit

The Spool wireless ethanol analyzer kit for the BMW Gen 2 B58 shows the real ethanol content and fuel temperature in your tank on your phone.

Why you need it

Fuel sold as E85 can contain anywhere from 51% to 85% ethanol, so a pump marked E85 might be closer to E55. Running less ethanol than your tune expects can damage the engine. The kit pairs a GM ethanol sensor with a Bluetooth 4.0 low energy module that barely touches your phone battery and leaves its normal Bluetooth connections alone.
