Alan said, That
is why it would need to be tested which should be pretty simple in run-up,
etc.
Alan, I agree with your LOGIC concerning how the
system SHOULD work.
However, I totally disagree with what you propose
here for testing the high boost on TO option. You would want to know that your idea works through the range of fuel
temp, rpm, deck angle, outside air pressure, outside air temp, engine temp,
variations in engine fuel pump mfg tolerances, wear
etc. That's a sizable testing
proposition.
Meanwhile, the few data points I have say that
the system is sensitive to input pressure. e.g. there have been
conditions where my engine was fine without boost but very unhappy with
it. In this case the idle mixture was out of adjustment but it
still proves that the fuel is NOT
correctly metered no matter what the input pressure.
Also, coupling even a tested policy to a computer
would then require extensive software testing also.
...at least if I were going to bet my life on it. (I've spent too
many late nights wondering why my program "DID THAT" to take software testing
lightly)
My solution is going to be to learn where the
high boost button is and be cocked to hit it if necessary.
