Ethanol blends or full E85, those are the magic words when tuning the BMW engines with high compression ratios. The mixture of E85 can vary from time to time, and especially when using blends such as E20 or E40 – filling up and keeping track of the current ethanol content can become a nightmare.

For safe tuning and choosing the correct ECU map for current mixture, real-time analyzing of ethanol content is critical.

With Spool wireless bluetooth sensor, you’ll be able to keep track with your (free) Spool mobile app whenever needed.
