    RPM signal from MSS54 ECU?

    If irc the RPM is to be found at X60004, pin17.

    Does anyone happen to know the frequency range (or conversion factor) for the RPM signal comming from the MSS54? Like 0-xxHz <=> 0-9000 rpm, the conversion factor in Hz/rpm or rpm/Hz?


    Thanks.

    I have tapped into that signal in the past using a RaceCapture Pro. Should be 3 pulses per revolution since S54 a 6 cylinder engine.



    However I use the CAN data now. At higher RPM the signal gets noisy. Needs some smoothing.
