    Bumping this thread and posting that the flex fuel pin is pin 4 on the bottom connector on the E40.

    Again, Pin 4, C3

    Relay on IAT works rather well.. you could use our LPE Signal generator/switcher for E85 pin. Works rather well.

    If there was enough interest I could do a nitrous custom OS for this.

    So i installed a flex fuel sensor on an e40, turned the switch on and set dtc fault codes and everything worked as expected.

    the only thing I needed to take into consideration is we are missing a couple of extra tables inputs for transition between percentage changes, if you install the sensor close to the fuel pump it's probably not much of a concern. but on this particular car i installed the sensor on the outlet of the rail before the reg & with the default transition values it took some time before the ecu started compensating for the ethanol change.

    In the end i just chewed up a credit with my hpt cable to zero it out, so it changed instantly.
