Open source ethanol content analyzer that converts signals from Continental Flex Fuel sensors into 0 - 5V analog signals for ECUs.
Project built using PlatformIO and targets the Arduino Nano Every. You can learn more about the project on my blog
More details soon! For reference, check out these great tutorials on NASIOC and FT86Club.
This setup should work with other cars whose ECUs expect a 0 - 5V signal (as opposed to CAN input). This was tested on a Subaru BRZ.
