Realtime Ethanol Content Data - Via OBDII Or Dedicated Device?

YamahaRick · Mar 27, 2026

I plan to get an E30 tune when I buy a tune for my 2015 SHO. Only mod will be exhaust, probably full SSW.

Since I will rely on unreliable gas stations for a mix of 93 octane and E85 (which can vary in ethanol content) to achieve E30, I want/need to monitor exactly what I have.

Is real time data available via the OBDII port? How about a dedicated standalone device?

TIA.

The cars don’t have a ethanol sensor so a lot of people run the fuel it Bluetooth set up which uses the GM sensor

been running fuel it since Matt at GH recommended it. Eventually I will get around to wiring it into my aeroforce gauge instead of connecting to the app. The app does use you current e content to calculate what to mix to fill up
