Table 508 Piston engine mechanical efficiency...
I can tune this table to match either...
a) power vs. altitude
b) power vs. manifold pressure
But, carefully matching either one leaves the other distorted.
It seems like the best solutions is a compromise…neither is ‘right’ but the sum is somehow least ‘wrong’.
So…
I can find a value that will match exactly how power drops with throttle at sea level.
But the power will then drop off too fast with altitude.
Or …
I can find a value that will match exactly how power drops with altitude.
But the power will then not drop enough with throttle.
There is no other method to tune efficiency (?).
Aye...what’s the solution? Any suggestions?

This chart just for illustration, but it is the one I'm trying to match.
