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
I deciced also to create my own motherboard to bring the system more stable dans a bunch of welded cables
Bought some aliexpress boxes
Put some solid connectors (1 for power and 2 for ECA)

Did my own loom measured for the Mazdaspeed6 bay
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 !
