Open the app. Then click on the gear icon and go into the settings area. Then go down to the "Manage extra PIDs/sensors and click it.

Click on the 3 dots in the right corner and click "add custom PID"

I hope this next part makes sense. One each of these sections in the custom PID fields add the data I have for each section. If there is nothing in the section, leave it blank.

- OBD2 mode and PID - 220052
- Long name - Ethanol %
- Short name - E85
- Minimium value - 0.0
- Max value - 100.0
- Scale Factor - 1x
- Unit type - %
- Equation - (A/255)*100
- OBD header - Leave blank
- Diagnostic start command - leave blank
- Diagnostic stop command - leave blank
- Overrides PID - Does not override any PID
- Remember equation function data - I used store value globally

That should be it, then you just need to add one of the graphs to your screen and choose the one you named E85.
