Yes, i aggree on that. This Piece of hardware provides the same functionallity as other ECA:s on the market do. It only helps with transforming the 50-150HZ output from the ethanol sensor to a 0-5 volt that can be read by the ECU.
With this opensource hardware you still need a custom flex-fuel tune that is coded to to read the 0-5 volts that the ECA outputs. But, since this hardware works in the same way as for example the Zeitronix ECA does then you should be able to use the FlexFuel tunes that Moto-East and other sells.
I have drawn two basic diagrams on how this one can be used.
- Option 1, Use it as a standalone ECA.
- Option 2, connect it to an existing FlexFuel installation if you want to have the Ethanol Content output available via Bluetooth instead of a additional display.
