Default RE: MVVS / Evolution 58 tach Readings please.

Is this the engine that has an "attachment" to count rpms electronically? I don' t own the engine but it seems that the technology should be there since the ignition system is "counting" how many times the sensor passes the magnet anyway. Maybe I am not expressing this correctly but hopefully, you know what I mean. Seems natural all electronically fired engines should have that capability sooner, rather than later.

I was getting around 5750 RPMs using big wide Top Flite 24x10 prop. I had converted the engine to use the CH-Ignitions system versus the old Valach ignition system. CH-Ignitions has a really nice CNC machined amuminum sensor carrier. Plus the sensor only works with the one magnet, ignoring the second magnet, if you have the oder two magnet Valach system.
