DIY Ethanol Content Gauge

[JFSpeed3]

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.

Got my 16x2 screen in the mail and it seems to fit perfectly in the place I was initially planning. With it here I don't need to worry about dinning the screen at night time. I'll probably make it a little bezel out of aluminum or lexan and then mount it all up!

Yeah I definitely followed that when he was in development. Very neat little device to grab if you often run ethanol.

I am updating the layout to add a sensor with cheaper parts and line that is easier to work with.

What about using this with a flex fuel tune so that it will adjust your tune on the fly depending on your ethanol content. I know there are other after market setups that are doing that.

Not possible on this platform.
