Has anyone actually verified the rpm readings from the
EM-2?  I have no particular reason to question it, but it would be good to
know that the EM-2 readings are accurate within some factor.

Hi Mark,

I'm assuming that you also have an EC-2.  If that's the case, I'm pretty sure the EM-2 is getting it's RPM data from the EC-2.  If the EC-2 doesn't know the exact RPM of the engine, we're all in trouble :-)   

Seriously, I never questioned it for a second, but you can call Tracy and see if there's any way it could be wrong.
