    Rotax Racing stock class 8300 ECU and knock sensor

    Does anyone know if this ECU actually has the knock sensor? It doesn't say "Without" on the label. This is an 07 ECU.

    i am 95% sure the rotax racing ones do not, its one of the big differences between the riva and rotax ecu's from memory.

    Can anyone confirm that the Rotax ecus do not have a knock sensor?

    Why would they omit a knock sensor?

    Thank you.
