    Default External input

    Can someone tell me the sampling rate for the external ch?

    How fast can EFI track a changing voltage?

    Is there a configuration for a pulse counter?


    Thanks!

    Given that the quickest sample rate is 10 frames per second I wouldn't expect you to see any more than that in a log file. I think most WB02's sample at more than 10 fps but you don't get the extra resolution in the logs.

    What I like to use the input for is supercharger rpm.

    You could always use a frequency to voltage converter like nationals LM2907
    and run it to your analog input.
