So, time for a update on this Project since I have had some work done on it lately.

I have received the PCB and the Components and successfully assembled the protoype board. On this one, the Components was manually soldered. The next ones will be soldered in a reflow oven and not by hand.

This prototype is fully working and it contains a status indication LED as well as Bluetooth output. The next few Days will be spent on fine tuning the software and then its ready to be installed into my GT86.

As said earlier. This PCB provides the same functionality as others ECA:s on the market, but its much cheaper. This can be used in any flex-fuel or ethanol setup where you either want a output via Bluetooth AND/OR an 0-5V analog output that can be used by the ECU.

I will release the code and the schematic so if anyone want to build it by them selfs. I will sell some of the board prefabricated but I will need to add an additional cost for the assembly since it takes some time for me.

Here is my prototype module which is fully working (missing some of the wires for the Power input as well as the wires to the ethanol sensor):
