RPM signal from MSS54 ECU?

[racing-iot]

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.
