Alcohol Density Reading from OBD app

Question for the OBD crowd using OBD fusion, Torque Pro, or other app.

I have been using OBD fusion for sometime, purchased the expansion pack for my truck, and built a dashboard I use on occasion. Yesterday I noticed I am no longer getting an Alcohol Density Reading. It stays at 0 and the "status of density learning" stays at 0 too. I used to get readings within a few minutes of driving so something has changed. The only event I can point to since I last used it was I had the Fuel Pump replaced under warranty and i think they reprogrammed something too.

Anyone else having the same issue based on cicumstances? Or thoughts about the issue?

2018 5.7 FFV

 

It seems to stabilize once you've ran a few tanks through. At least mine did after i reset to 0. Like it averages out with more data points maybe? Who knows...

 

Yes, the dealership would have reset it when they did the fuel pump.

I had mine reset a few months ago and I am still at 0. I never use e85

 

Good to know, thanks. Very strange as I used to watch it calculate every time I filled up and could see which stations had higher ethanol percentages. Better it sits at 0 than the other end of the spectrum.

 

Curious about this myself. Mine was at 18% even using non ethanol. Reset it and its still at 0% after 2 months using E10.

 

Hey Bro! Do you mind if you post or DM me the PID for those 3 alcohol readings? I also have FFV and would like to monitor the alcohol readings as well. Thanks!

 

From within the OBD app i use the "Alcohol Density Estimate" and the "Status of The Alchol Density Learning:
