Angier,
Your prop did not over speed. Note that while the pump was running
the voltage was lower than during the time the pump was not running. While
13.2 VDC is not that low, the MVP may be sensitive to that or to an unusual
ground loop relative to the pump ground. The same may
be true for the fuel flow sensor. Check it out.
I like the hydraulic pressure included in the data logging.

PS do not worry about 2710 rpm.. You may want to change the limit
values slightly. Then again, why did the mstr wrn go away or did you reset
it.

Today's
2hr flight was normal in all respects with the single exception that
immediately after liftoff, the MVP-50 began screaming 'check RPM'. The RPM
display was close to 4000 and fuel flow spiked.
Nevertheless engine sounds
remained normal. Sure got my attention.
At 6:29:28 and just as the gear
started to come up is when the RPM indication spiked for all of about
5
seconds. Haven't seen this before.
What would the common, everyday prop
overspeed sound like?? not that I ever want to hear it....
