    .
    The Arduino Nano co processor on a screw terminal breakout board and a 12 bit DAC for realistic analog output that is usable as a MAP signal for the EFI's CPU.

    Hopefully get to try this out on the bike in the next night or two. If it looks promising I will post the code, if not its back to the drawing board.

    Arduino Nano MAP co processor setup ready to test. Hopefully tonight.

    In case it might be of help, 55641075000 is the part number for the KTM TPI MAP/crankcase pressure sensor, US$39.31, (listed with the oil pump instead of the throttle body/ECU where I expected to find it). It seems like it should be some standard bought-in component. It may be worth your getting one to see if KTM specified something out of the usual range of sensitivity compared to MAP sensors sold for 4T use. Or if it matches up to what you are using you'll know you probably aren't too far off on your setup.

    There's a KTM/Husky TPI thread at advrider and the sensor seems to often get replaced when people's bikes are having problems running correctly.

    cheers,
    Michael
