    Hi fellows, here to talk about my DIY Ethanol Sensor Interface...

    First I create a worbench lithe you can see below

    This simulate the car's fuel circuit (even if we have returnless fuel circuits)


    The I used an ESP32 dev board with a 0,96mm QLED display and write my code, adding also bluetooth capabilities and Wifi AP to connect from my car's Android headunit and see the values in a gauge style html page

    And the final result in a video (Android Application coded by myself)




    P.S. Have an explanation video but in French, I think that is not pertinent to pot here

    Cheers fellows !

    Long life mazdaspeeds !
