DIY Ethanol Content Gauge

Thanks to all that contributed to this project! I'm glad I found it. I had been looking into the arduino + nextion for a diy car gauge project collecting as much info as I can. I'm kind of a research-a-holic before I start doing anything project related. I'm no where near starting this diy project, just starting down the bolt-on path on my speed, but this is on my diy projects list.

 

Of course! If you have any questions or things to add, please comment! Unfortunately I never got to the point of installing it all (as I parted out) but I had the whole setup working outside of my car.

 

I'll definitely pick your brain once I get this started. Thanks

 

I have been lazy and not wanting to spend the 100$ on plumbing to get the e85 meter in the stock fuel line. The arduino and sensor all seem to work so really that is the last hurdle. I had posted what I think would be needed to route it into the stock system. if you have any genius ideas they are also welcome.
